Organic Christmas waste: how can it be useful for your garden?

Did you eat a lot this Christmas too?

But what have you done with apple peels, orange peels, cheese peels, fish flakes, olive pits, meat fat and all those leftovers you haven't eaten?

In this article, we explain how to use Christmas organic waste.

Compost and organic matter

The organic substance it is nothing more than the set of organic compounds (compounds in which carbon is present) of animal or vegetable origin. It is in a sense "The soul of the soil", the one that allows the growth of our plants. The organic substance, in fact, is full of useful elements: Nitrogen, Phosphorus, Potassium, Calcium, etc. All components that the plant feeds on and which therefore cause its growth.

The compost, on the other hand, also called compost or compost, it is the set of earth and the result of humification of the organic substance. In other words, once the organic substance has decomposed (that is, it has been reduced to small elements, after the chemical bonds between them have been broken), a set of earth and nutrients highly assimilable by all plants is created.

Who decomposes organic matter?

Imagine you are sitting at the table, ready to eat. If I hand you a pan of lasagna in front of your eyes, would you eat it all in one bite? No, right? What would you do?

What we would all do is take a piece, put it on the plate and, with a fork, divide it into other small pieces which then will be our morsels. Here, unfortunately, plants cannot do this.

Plants, in a sense, they are like children: we must be the ones who divide their food and make them as assimilable as possible. But how?

There are gods microorganisms, especially fungi and bacteria, which decompose the organic substance. Some can be purchased commercially and could be very useful if you want to speed up the decomposition process.

Humic acids, for example, are one of the results of the decomposition of organic matter.

Organic Christmas waste: how to make compost

To use organic Christmas residues in your garden, you can put them both whole and after composting.

Usually, I suggest you avoid throwing them whole directly on the ground because animals could go there to feed on it, and because, in any case, it would take much longer to decompose, especially now that temperatures are low and the ground may be covered with snow or ice. So here is where it comes in handy to compost. But how? Is simple!

  1. Just take it a large container, depending on the amount of compost you want to create. There are many on the market which were built specifically for that purpose.
  2. Before you put the organic Christmas waste in the compost bin, remember to put also a little soil and a few balls of expanded clay.
  3. Bacteria that break down organic matter need oxygen to live. So it's important DO NOT compress organic Christmas waste when placed in the container.
  4. Once the composter is ready, you can put the waste organic Christmas. To obtain a good composting it is better to use kitchen leftovers: vegetables, peels, skins, tea grounds, coffee grounds, pasta, sauces, oil, etc. You can also place the twigs and dried leaves that you have collected in your home garden.
  5. At least 2-3 times a week, that's fine open the composter and mix everything. This helps the decomposition of organic matter and the creation of humus. In particular, you will need to mix the wettest scraps with the less moist ones.
  6. At the time of mixing, it must control the humidity: the right humidity occurs when, after picking up a little compost, droplets of water come out. If this does not happen, it is good to pour a little water into the container, approximately 15-20% of the total volume.
  7. Also make sure that there is the constant entry of air. Many purchasable containers already have entry holes. If they don't have them, you can do them yourself.
  8. Also check the temperature. At the beginning it will rise, and then slowly lower towards the end of decomposition until it reaches room temperature.
  9. Remember that a good composting does not give off unpleasant odors.
  10. To add Phosphorite or Superphosphate, to increase phosphorus levels, e wood ash, potassium sulphate or potassium chloride, to increase potassium levels.
  11. Now you can wait for spring, so you can see how useful your Christmas organic waste has been for your garden.

Separate collection of staff at Christmas: CIC helps us to clarify

Share this article

The Christmas period is always a chaotic time, in which more waste is produced and often a lot is wasted. Below we got help from CIC - Italian Composting Consortium to understand how to deal with organic waste.

Christmas and New Year are two critical moments when it comes to waste, especially those organic, whose production tends to increase. A first step is therefore to reduce food waste, starting from what you put in the shopping cart, then thinking carefully about the portions, but also paying attention to what you throw in the bin. For this, the Italian Composting Consortium (CIC) has drawn up a handbook for the separate collection of quality organic waste and without waste, to be kept at hand during all holidays.

  1. Prevention is better than recycling!: when shopping for Christmas lunch or New Year's dinner consider the amount of food you actually need. Consult the storage instructions and - above all - the expiry dates. The wording "preferably consume by" means that after that date the food is still edible, in some cases even for months, and eating it does not risk any stomach ache.
  2. Donating can be a concrete gesture: in Italy, initiatives for the recovery and redistribution of food products from the distribution and / or catering sector have spread, in cooperation with non-profit structures or social services. Look for those active in your city and contact them to see if you can send them the food still packaged, or if you can support them financially. If you organize banquets or dinners with a large number of guests, you could also donate part of the cooked meals.
  3. Zero waste in the kitchen: before throwing leftovers in the humid dish, ask yourself how to reuse them: leftover or overripe fruit can be used in excellent fruit salads, while small leftovers of vegetables can be mixed in a rich salad. Tomatoes that are starting to wrinkle can be dried in the oven, sprinkled with oil and herbs and then stored in an oil-covered jar.
  4. Use the right bag: organic waste must be disposed of using bags in biodegradable and compostable material certified to UNI EN 13432 in paper or bioplastic. To recognize a bag that complies with the law, you need to check if it says "biodegradable and compostable"The wording of the European standard" UNI EN 13432: 2002 "and the logo issued by the certification body, such as the" Compostable CIC "mark. Traditional plastic bags, which by law cannot be used for the collection of organic waste, should be avoided.
  5. What to put in the organic basket: what can be thrown away in the workforce? During the holidays at home fruit and vegetables will almost inevitably increase: with the humid all the food preparation waste, both vegetable and animal, can be collected, while care must be taken never to throw non-compostable materials such as glass objects. metal, plastic. A tip: before throwing the organic waste into the bag, drain it and instead of pressing it, reduce the larger ones to small pieces. Also, allow cooked foods to cool down to room temperature to prevent compostable bags from melting. A correct collection of organic waste, both cooked and raw, allows to transform these leftovers into biogas (renewable fuel) and compost, a natural fertilizer that returns organic substance to the earth.
  6. Compostable tableware: don't want to put good service on the table? On the market there are crockery (plates, glasses, cutlery) in certified compostable material (pursuant to the EN 13432 standard) that can be transformed into compost, in industrial plants, without constituting waste to be disposed of. Before collecting these artifacts together with the wet waste, check with the manager or the collection company if this path is feasible in your municipality.
  7. Pay attention to the collection calendar: on the occasion of Christmas and New Year it is possible that the separate collection times may be changed: consult the calendar carefully!
  8. Christmas tree if you have purchased a coppice tree (without roots) you can start it for recovery with the separate collection of the green waste of your municipality. Find out about the correct collection methods and check if you can deliver it directly to the Collection Center of your municipality. It can be sent for recovery in a composting plant, returning energy to the earth in the form of compost, an organic fertilizer.

We thank CIC - Italian Composting Consortium for these valuable tips and we hope that you can follow them avoiding unnecessary waste and above all harmful to the environment!

The production of humus or worm compost

Earthworms are producers of an extraordinary natural soil conditioner, which is called vermicompost or humus. This humus is a fertilizer with multiple properties: it improves the structure of the soil, making it soft to work and increasing its water retention capacity, and makes all the nutrients they need available to the root system of crops.

The fact that the vermicompost is 100% natural makes it possible to avoid using chemicals and makes crops healthier, and is also allowed in organic farming. Humus is a very interesting product on the market, it can be sold to farms, especially organic ones, to gardeners and nurserymen, but also to those who cultivate a vegetable garden as a hobby.

Separate collection of organic waste

Separate collection of organic waste

Organic waste, or wet waste, is sometimes even called wet / organic, make up about half of the total waste that is produced in a family, and all of that are part of it biological materials, and therefore not synthetic, which can never be missing at home, if only because, for the most part, they are represented by leftovers such as fruit peels, meat fat, etc.

Organic waste can also be recycled, and the most common use made of it is the creation of compost, the fertilizer for plants. If you have a garden, a vegetable garden, or plants, you can bury this kind of waste to make it fertilizer, or you can create real compost.

How to separate organic waste

Wet / organic waste must be disposed of in the appropriate bin which is brown in color. The waste that can be included in this case are:

  • Fruit residues, including peels and shells
  • Kitchen residues such as coffee grounds
  • Deteriorated foods, such as pastas, bread, or expired meat, including fish bones and bones
  • Soap
  • Remains of gardening (grass, leaves, cuttings, soil, etc.), known as the "green fraction"
  • Non-hazardous waste
  • Chimney ash (make sure it is extinguished!)
  • Cat litter.

On the other hand, waste from other materials that can be otherwise recycled (glass, plastic, etc.), used diapers, oil and medicines, cigarette butts or fabrics should not be placed in the appropriate container.

Once these wastes are created, they must be carefully separated from the others, the green and wet fractions must be divided into different bags which must always be biodegradable. At this point it is possible to dispose of everything in the appropriate bins.

Disposal of waste

The ecological function of the earthworm is to transform organic waste into humus, this can allow the company that practices earthworms to add a profit by charging for the waste disposal service.

Dispose of manure

Earthworm farming is a perfect solution to comply with the Nitrates Directive, which regulates the obligations that livestock farms have to meet. Earthworms can therefore be used as an ecological method to recover manure from various farms (rabbits, cattle, pigs, horses, poultry,…).
The value for those who raise earthworms is double: on the one hand you get feed for your worms, on the other you get income for disposal.

Organic waste transformation

Earthworms are able to transform not only manure but in general any organic material: foliage, paper, cardboard, shredded pruning residues, vegetable, garden and kitchen waste, weeds, residues from the food industries, sewage sludge, ...

Treatment of waste from separate waste collection

Given the earthworm's ability to transform organic waste, it is possible to use worm composting as part of separate collection, to treat the wet fraction (FORSU). This is the least expensive way to recover this type of waste, which is why some public administrations have introduced this system as innovative as it is simple and cheap. Some examples: Marzi, San Cipriano Picentino, Paterno Calabro and Saracena.

Congratulations on your work which is understood to be the result of so much passion and professionalism.
I recently resumed running the small family farm located in the Tuscan Apennines, exactly in the Casentino, about 800 meters above sea level. In my very small business I would like to always move with the principle, (once so obvious in the common activity of peasants, and today, alas, declaimed and little practiced) of circularity and complementarity of the different activities. This is why I am already practicing natural fertilization using the compost produced from the vegetable waste and manure of my 24 hens. I would now like to start humus production with a first litter in order to be able to adequately integrate the fertilization of the soil. for this I would have some questions:
1) are there any contraindications for earthworm farming in relation to the altitude, which in my case is 800 meters above sea level and the presence of snow and cold in the winter season?
2) currently I have grown about 1000 square meters of soil as a vegetable garden. These are well-drained terraces and non-clayey soil of good fertility. But I don't know the ph…. How many square meters of litter do I need to prepare in relation to the square meters of cultivated land and to fertilize? (I specify that the crops are for family purposes and include all types of vegetables as well as a plot of potatoes).
Thank you!

Hi Luca. I share your principle of circularity, so I fully support you, you do very well to try to create a self-sufficient system. In biodynamics, the farm is conceived as a single organism and it is believed that manure and compost derived from the place where it is grown are more suitable. On your first question I believe you can raise earthworms without a problem. For a more authoritative opinion you can try to contact Luigi Compagnoni, through the website of Lombricoltura Compagnoni, he is the person who helped me on the technical side of earthworm farming and is one of the leading Italian experts in the sector. On the second question: you can measure the ph in a very simple way, with a little distilled water and a litmus paper, the square meters of litter I would not be able to advise you exactly, if I were you I would start on a small scale, gradually expanding until you can dispose all your waste and to produce enough humus.

Already with the first spring sunshine in the garden, the work begins. Plants need to be prepared for the summer season, cut, whitewashed, treated with pests. Towards the end of March, right along the ice crust, the first fertilizers are introduced. The choice of them is huge, and novice gardeners may find it difficult to understand what and when to do. In this article, we will talk about proper garden nutrition.

  1. Mineral fertilizers for the garden
    • Phosphate fertilizers
    • Potassium fertilizers
    • Nitrogen fertilizers for the garden
  2. Organic fertilizers
    • manure
    • Bird droppings as a fertilizer for the garden
    • fertilizer
    • ash
    • sapropel
    • A variety of organic fertilizers for the garden
  3. "Healthy garden" homeopathic fertilizer

  5. Mistakes that cannot be made when applying fertilizer

Mineral fertilizers for the garden

Phosphate fertilizers

The most common fertilizers with phosphorus content are phosphorus flour and superphosphate.

  • Most summer residents choose superphosphate tested over decades as granules, with a phosphorus content of 48%. The moment of its introduction into the soil depends on a certain culture, but nevertheless it refers to the autumn fertilizers that are introduced under the excavation of the soil. This is due to the fact that phosphorus is needed to form a good root system, which is so important for the successful wintering of plants.
  • With the application of the spring, the number of flower buds increases, stimulates the formation of fruits.

Tip: Phosphoric mineral fertilizers are not recommended to be applied simultaneously with lime, as it interferes with the assimilation of phosphorus by the roots.

  • The fertilizer consumption is always indicated on the package, for example for double superphosphate it is 80-100 g / m2.
  • For faster assimilation of phosphorus by plants, it is recommended to prepare a liquid top dressing. To do this, superphosphate is soaked in water for three days. For irrigation, only liquid fertilizer is suitable, and the sediment can be poured into the compost pile.

Potassium fertilizers

  • Potassium increases the resistance of plants to unfavorable external factors, such as frost, drought or pests. Experimentally, potash fertilizers have been shown to help significantly reduce the degree of plant damage from fungal diseases. But it is quickly washed off by rain, so its regular introduction into the soil or spraying is required.

  • It is better to introduce potash fertilizers along with phosphorus fertilizers. However, it is recommended to exclude the combination with nitrogen. This is due to the fact that potassium increases the amount of carbohydrates in the root system that are so necessary for the formation of mycorrhiza, but nitrogen fertilizers begin to use them to form their organic compounds.

How to use potash fertilizer correctly:

  • It should not be used when growing seedlings and when transplanting garden plant seedlings to a permanent place
  • for arid areas or for fertilizing plants in greenhouses it is better to use granular potassium sulfate, and for regions with frequent rains, potassium nitrate or potassium chloride will be produced
  • for acid soils it will be better to use potassium chloride
  • they are compatible with almost all fertilizers
  • potassium fertilizers arrive at the roots of the plant only after dissolving with water, so when you do it it is important to water them, but not too much. Otherwise, the potassium will simply dissolve without having to suck up the roots
  • it is recommended to make them in a small amount, but often. This gives a better result than twice as high a dose per season
  • it is impossible to pour top dressing directly on the stem of the plant, it is necessary to retreat by 15-20 cm

Nitrogen fertilizers for the garden

Popular fertilizer containing nitrogen, which is suitable for fertilizing the garden in the spring:

  • all types of saltpetre (sodium, potassium, calcium, ammonium)
  • urea, the second name is urea
  • NPK.

The highest percentage of nitrogen is in ammonium nitrate, where it is 1/3 of the fertilizer. But taking it into the ground should be taken into account that it significantly acidifies the earth, so together with it it is recommended to make lime.

How to use nitrogen fertilizers correctly:

  • It is not recommended to introduce it together with fertilizers containing phosphorus (superphosphate or phosphorus flour)
  • for watering seedlings in the spring or rooted seedlings in the summer, it is better to use a liquid solution. To make it at home, you need to dilute 10 g of ammonium nitrate per 10 liters of water. Ammonia solution is not only poured under the root, but also sprinkled with foliage. Hence, organic substances are quickly absorbed by plants
  • with a dry application, it is recommended to apply nitrogen fertilizers in spring or in the first half of summer, as they stimulate the accumulation of green mass. The exception is the garden strawberry, it needs nitrogen at the end of the summer, so that it will have time to grow more leaves in the winter, which will protect it from winter frosts
  • with the exception of food, nitrogen-containing solutions can be used to combat plant diseases. For example, urea with a high nitrogen content (46%) is perfectly suitable for the prevention of scab or mold
  • for acid soils, it is advisable to discontinue the choice on calcium or sodium nitrate. Although their nitrogen content does not exceed 15-16%, they perfectly stimulate plant growth without acidifying the soil
  • Do not use in your garden nitrogen fertilizers, which contain chlorine additives. Not only do they worsen the composition of the soil, but they can also adversely affect the physiological development of many garden crops
  • under fruit trees and bushes, nitrogen fertilizers are introduced 2 times per season. First in the spring, when the ground warms up and there is no likelihood of reverse frosts. And the second time - in the early summer. If the soil is clayey, fertilizer, such as ammonium sulfate, can be introduced until the fall. But necessarily bury in the ground, otherwise they quickly lose useful properties
  • to get them into the logs, they should be evenly distributed. If the soil is dry and rain is not expected, then water it. This will prevent a root system burn.

Organic fertilizers

You can not only buy fertilizers for the garden, but also make them yourself.


  • This is undoubtedly the most popular organic fertilizer in vegetable gardens and villages. Depending on who (cow, horse) depends on the dosage and how it is introduced into the soil. But in any case, it cannot be used fresh, since all the substances necessary for the plant are still in an unused form.
  • When manure settles, decomposition processes begin, forming a large amount of toxic gas for plants. In addition, the risk of germination of weed seeds is considerable, which did not have time to fade.

How to properly use manure as a fertilizer:

  • before application, manure must necessarily be turned over. To do this, put it in a pile, sprinkle the top with a layer of peat 20-25 cm and leave it for the whole summer. But this method is not suitable for horse manure, it will run out. It is recommended to leave it for a short time (no more than 2х3-3 weeks)
  • for a higher concentration of fertilizer, manure can be added to mineral fertilizers. Thus, 100 kg of manure requires 1-2 kg of superphosphate. It is desirable to add this fertilizer to the soil once in 2 seasonal seasons. The cost depends on the fertility of the soil and on average is 5 kg / m2.

Bird droppings as a fertilizer for the garden

Bird litter is worth mentioning separately, insofar as the concentration of nutrients for plants is significantly higher than cow and horse fertilizer.

  • In its pure form, it cannot be applied to plants even from those that have rotted, only for the autumn or spring digging of the soil. On average, consumption per square meter of land should not exceed 250 g.

  • Use it to fertilize plants in the summer it can only be in liquid form. To do this, fill the tank with bird litter a third and fill it with water. To make the solution mature, it should be mixed for 3-4 days. But even in this case the concentration remains too high, so before the direct application of a solution under a plant, it must be diluted with water 4 times.


This is an excellent organic fertilizer, which practically does not require financial investments.

  • It is done in many ways, each of which has its advantages and disadvantages. For example, many dig a compost hole and add organic waste, sloping grass, and other unnecessary vegetation during the summer season (except for weeds that may eventually sprout). This method is the cheapest, but to make compost you have to pull the entire heap. And due to the lack of air access, the decomposition process is a bit slower.
  • The second way - compost boxes. They are sold already made of plastic or made by themselves. The main thing is to provide a door at the bottom, through which it will be convenient to take compost in the future. To accelerate the ripening of fertilizers, it is recommended to use special compounds, for example, "Baikal". In addition, the compost pile can be periodically watered and covered with a film. Some gardeners add bird droppings to the compost pile.
  • To prevent an unpleasant odor due to the ripening of the compost, each layer of new waste must be covered with peat.
  • If shredded branches or sawdust were added to the compost, then in this case it will not be suitable for fertilizing the soil until after 1-1.5 years.


Hardwood ashes make an excellent addition to mineral fertilizers. It is rich in phosphorus, potassium, calcium and a number of other microelements, which are easily assimilated by plants.

How to make ash correctly:

  • In the place protected from moisture, the ash can be stored for years, while the calcium, phosphorus and potassium will be preserved. But it is more convenient to do it during the entire vegetative period directly from the stove
  • The ashes are always poured into the plantation pit, along with fertilizer or overripe manure. The soil filled in this way within 3-4 years will give the plant useful micronutrients, which means that it will no longer need additional fertilizers
  • under the young plants, the ash is dispersed in early spring. Together with the melted snow, it will penetrate into the surface roots and will be fed already at zero temperature
  • ash is good in that it contains a large amount of calcium, but there are no substances containing chlorine.


  • This is also a type of organic fertilizer. Sapropel is a deposit from the bottom of tanks, which rotates with the silt and thus accumulates useful trace elements. It can be added to compost or mixed with mineral fertilizers when planted.

A variety of organic fertilizers for the garden

  • "Darin" - this is a whole series of drugs, but they are all made on the basis of sapropel. They also added a complex of mineral fertilizers, such as nitrogen, humic acids, phosphorus, potassium. Significantly affects the increase in yield.
  • EM It is the name of the fertilizer, which stands for effective microorganisms. It is added to the compost, which significantly speeds up its preparation (1-2 months). Most effective when done through composting in the fall. Suitable for poor soils and economical to use.
  • TMAU- Peat and mineral ammonia fertilizers. They are produced on the basis of peat, ammonia water, potassium chloride, superphosphate and a number of trace elements. It is suitable for dressing all fruit and berry bushes and trees. For the season, it is enough to add 1 kg of the mixture to the stem of the adult plant.
  • Top herb dressing. For this purpose, blunt garden grass, dandelion, nettle, plantain, mustard and mocryca are excellent. They fill a third of the container and fill it with water. A few days later the fertilizer will be ready. It is suitable for all garden plants, but has an extremely unpleasant smell.

  • Eggshell. Il guscio d'uovo schiacciato è ricco di calcio, inoltre aiuta a ridurre l'acidità del terreno. Si raccomanda di usarlo per nutrire bacche di olivello spinoso, ciliegie, prugne, perché queste colture reagiscono molto acutamente all'elevata acidità del terreno.

Fertilizzante omeopatico "Giardino sano"

  • Questo farmaco, inventato a San Pietroburgo e non ha analoghi nel mondo. È ecologicamente sicuro, poiché è costituito da granuli di zucchero raffinati, che sono strutturati sotto l'influenza di magnesio, potassio, sodio e persino oro.

  • Il fertilizzante "giardino sano" purifica le verdure dai nitrati, protegge le piante da parassiti e malattie. Si consiglia di utilizzarlo per coloro il cui orto si trova vicino alle autostrade.
  • Nel sito "giardino sano" viene utilizzato durante l'irrigazione o la spruzzatura di piante giovani e adulte. Poiché è venduto sotto forma di granuli, sarà necessario realizzare una soluzione in modo indipendente. Per fare questo in 1 litro, è necessario dissolvere 2 granuli.

  • le piante diventano più resistenti alla maggior parte delle malattie, tra cui la crosta e l'oidio
  • la loro resistenza alla siccità aumenta
  • è particolarmente efficace per i meli, dopo l'applicazione del farmaco il deciduo diminuisce più volte, a causa del fatto che le piante non sono affette da afidi, tignola della mela, mela della sega
  • l'accumulo di vari veleni da parte delle piante è ridotto. Che può entrare nel terreno insieme ai fertilizzanti
  • I fiori recisi durano più a lungo nell'acqua.

Concimi complessi

Sviluppati appositamente per i preparati vegetali contengono tutti gli oligoelementi necessari nelle giuste proporzioni. Sono scelti in modo tale che tutti siano assimilati con il massimo beneficio e rispettosi dell'ambiente.

  • "Il gigante" - fertilizzante granulato per tutti i tipi di colture orticole. Dopo l'applicazione, il terreno viene arricchito per 3-4 anni. Non richiede la dissoluzione in acqua. Quando piantare cetrioli o un pomodoro nella fossa di impianto, fare 1 cucchiaio. un cucchiaio di granuli.
  • "Berry" - come suggerisce il nome, è adatto per l'applicazione sotto cespugli di bacche. Soprattutto è piaciuto da fragole e fragole, che è danneggiato dall'eccesso di fertilizzante minerale. Non solo aumenta la resa, ma accelera anche la maturazione delle bacche. Per portarlo in primavera per 1 cucchiaio. cucchiai sotto la macchia e in estate, ancora una volta durante la maturazione del raccolto. Si consiglia inoltre di utilizzarlo per lamponi, caprifoglio, ribes e altri cespugli di bacche.
  • "Ideal" venduto in forma liquida in 1,5 litri. bottiglie. Questa preparazione altamente concentrata è adatta per la medicazione superiore di tutte le colture da giardino. Colpisce l'aumento della resa e la resistenza delle piante a malattie e parassiti, ad esempio, alla gamba nera e all'oidio. Viene anche utilizzato per l'alimentazione attraverso le foglie, previamente diluendo 50 ml della soluzione in 10 litri di acqua. Lo spray dovrebbe essere fatto due volte a stagione, spendendo 5 litri / m2.

La stella di Natale teme i marciumi e i ristagni idrici, che possono causare il deperimento delle radici e la morte della pianta stessa. Le radici in buona salute non devono essere troppo sottili, devono essere di colore bianco e piuttosto numerose. Si tratta di una caratteristica che è necessario tenere sotto controllo al momento dell’acquisto della piantina, in modo da non optare per una stella di Natale che risulti troppo debole e che fatichi a sopravvivere dopo le feste.

Come già sottolineato, il liquido contenuto negli steli della stella di Natale può essere urticante. Per questo motivo la pianta natalizia deve essere tenuta lontano dalla portata non soltanto dei bambini, ma anche degli animali domestici. La stella di Natala infatti, se ingerita da parte degli animali, produce una linfa molto irritante per il loro apparato digerente ed è causa di vesciche dolorose nella bocca, accompagnate da spasmi allo stomaco. (LEGGI anche: (Se si comporta così, il tuo gatto (o il tuo cane) ha mangiato la Stella di Natale e deve essere portato subito dal veterinario

I fusti e le foglie della stella di Natale contengono una sostanza denominata triterpene che risulta velenosa se ingerita o se entra a contatto con la pelle. Può causare irritazioni e problemi all’apparato digerente. Il contatto con la pelle può provocare prurito o bruciore temporaneo. In caso di contatto accidentale, è necessario consultare il proprio medico.
