The perennial tree plant Yucca is part of the Agave family. This genus unites about 40 species that are naturally found in the subtropical zone of North America. In the homeland of such a plant, it is used in various fields. From cut flowers, juice is extracted with a high sugar content. Strong fibers are made from filamentous yucca, they were used to make the first jeans, and then cotton replaced them. However, even today in the United States, yucca is added to the fabric used to make jeans, making it stronger and more durable. In addition, yucca fibers are used to make rope and paper, plus all this plant has healing properties.

Yucca features

Yucca is an evergreen plant with a low stem, which may have little or no branching. In some species, the stem is impossible to discern, while large spectacular leaf plates rise immediately above the soil surface, which are placed in a spiral. Large erect inflorescences reach about 200 centimeters in length, they grow from the middle of the leaf rosette and have a panicle shape. The bell-shaped drooping flowers reach about 70 mm in length, they have a white color. The fruit is a ten-centimeter box, inside of which are black seeds, reaching up to 10 mm in diameter.

When grown at home, the tree is recommended to be placed in a hall or a large room, because it can reach a height of about four meters. Such a plant looks very similar to a false palm tree. It should be borne in mind that flowering is observed only in an adult yucca, during which white flowers appear outwardly similar to bells. Such a plant is often used as a decoration for a large room, while those bushes that have several points of growth (branching trunk) are of the greatest value.

Brief description of cultivation

  1. Bloom... Yucca is grown at home as a decorative deciduous large-sized tree.
  2. Illumination... Needs bright light, which must be necessarily diffused.
  3. Temperature regime... In the spring and summer, the plant feels comfortable at temperatures from 20 to 25 degrees, in the autumn and winter, the room should not be warmer than 12 degrees.
  4. Watering... Immediately after the top layer of the substrate in the pot has dried to a depth of 50 mm, the plant is watered abundantly.
  5. Air humidity... Air humidity requirements depend on the type of yucca. Some species need systematic humidification from a spray bottle, a regular warm shower, and it is also recommended to pour moistened expanded clay into the pallet. However, some of the species grow under normal air humidity typical of living rooms.
  6. Fertilizers... In the spring-summer period, feeding is carried out 1 time in 15–20 days for this, a mineral complex fertilizer is used in half the dosage recommended by the manufacturer. The seamy surface of the leaf plates is moistened with a nutrient solution.
  7. Dormant period... Not pronounced.
  8. Transfer... It is carried out only if necessary after the root system becomes very cramped in the pot. This procedure is best done in the spring, while in the summer it is transplanted only when absolutely necessary. It is not recommended to replant very large bushes, but they need to replace the top layer of the substrate in the container every year.
  9. Soil mixture... The substrate should be neutral with a pH of 6.0–6.5. If possible, it is better to buy a ready-made soil mixture for yucca, while adding 30 percent of the sand (of the total volume) to it.
  10. Reproduction... Trunk sections, cuttings and seed method.
  11. Harmful insects... Whiteflies, spider mites, scale insects and mealybugs.
  12. Diseases... If the plant is improperly looked after or not provided with suitable conditions for growth, then its foliage may lose its decorative effect.

Yucca care at home

Illumination

When grown indoors, yucca should be provided with very bright lighting, since it is photophilous. However, despite this, the flower should be shaded from the direct rays of the sun, especially if it stands near windows with a south orientation. It grows best on the west and east windows. If natural lighting is too scarce, then the bush must be illuminated for at least 16 hours a day with fluorescent lamps, for this they are installed at a distance of 0.3–0.6 m from the plant. In the warm season, if desired, the yucca can be moved outside, while for it you need to choose a place that will be protected from direct sunlight, as well as from rain. If in the summer it is in the room, then it should be systematically and quite often ventilated.

Temperature regime

In the spring-summer period, make sure that the room is no colder than 20 degrees and not warmer - 25 degrees. If the tree has been exposed to direct sunlight for a long time, then it must be rearranged in a shaded place, and after it has cooled down, it is moistened with a sprayer. In the autumn-winter period, the air temperature should not be higher than 12 degrees.

If, during a warm winter, the lighting in the room is too poor, then the bases of the stems may stretch out, and the foliage will become thin, faded and lethargic. If the yucca weakens, it can cause an invasion of harmful insects, while the foliage turns yellow and flies around. If you cannot provide the plant with a temperature of 10 to 12 degrees in winter, then in the fall it is kept outside until the coldest days, and in the spring it is transferred to fresh air as early as possible. If a bush on the street is placed in a protected place, then even short-term frosts cannot harm it.

Watering

The following factors affect the frequency and abundance of watering a crop:

  • temperature and humidity level;
  • the size of the pot and the material from which it is made;
  • bush size;
  • characteristics of the substrate.

In the spring-summer period, watering should be abundant, it is carried out immediately after the top layer of the soil mixture dries out to a depth of about 50 mm. If the weather is hot in the summer, then watering should be more frequent, but still between them, the surface of the soil mixture should have time to dry out. If the yucca is cool, then the amount of watering is reduced, otherwise liquid will stagnate in the soil mixture, which will cause rot on the plant, and this can lead to its death.

Air humidity

Some yucca species when grown at home must be systematically moistened from a sprayer. To do this, use boiled water at room temperature. To maintain high air humidity, moistened pebbles or gravel can be poured into the pan. When wetting the bush, it should be protected from direct sunlight, otherwise burns may form on its surface. In order to remove dust and dirt from the foliage, the bush can sometimes be washed under a warm shower, while the surface of the substrate must be protected from liquid ingress.

Fertilizer

In spring and summer, such a crop should be fed regularly once every 15–20 days. For this, a diluted mineral complex fertilizer is used. The plant responds well to feeding with infusion of mullein, leaf humus or horse manure. However, experienced florists recommend spraying the seamy surface of the leaf plates with a solution of a complex mineral fertilizer. If the plant is sick or it was transplanted not so long ago, then feeding should be suspended, since at this time they can only harm it.

Pruning

As a rule, a yucca has only 1 trunk, but with proper pruning, it can form several trunks. To do this, you will need a young bush, which should be healthy and strong, while its height should be at least 0.3 m. In the last spring or first summer weeks, cut off the upper part of the bush, for this you need to use a very sharp tool. You need to cut off only 50-100 mm, but so that as much foliage as possible remains on the bush. Be sure to process the cuts, for this they are sprinkled with coal powder.

Yucca transplant

It is better to transplant the yucca in the spring, but it can also be done in the summer, if the need arises. At the bottom of the container, before planting, you need to make a good drainage layer; for this, use expanded clay, pebbles or broken brick. The substrate should be medium neutral with a pH of 6.0–6.5 if it contains peat. About 30 percent of the sand (of the total volume of the substrate) should be poured into the finished soil mixture.

It is recommended to transplant the yucca using the transshipment method, while trying to keep the clod intact. If rot appears on the root system, for example, due to stagnation of liquid in the substrate, then the plant must be transplanted as soon as possible, while the decayed areas are cut out. Yucca is well suited for hydroponic cultivation.

Reproduction methods

Growing from seeds

If desired, yucca can be grown from seeds. For this, freshly harvested seeds are sown in a substrate consisting of sod and leafy soil, as well as sand, which are taken in equal parts. Crops should be systematically watered, ventilated, and condensate must be removed from the surface of the shelter. The first seedlings should appear after about one month. After the seedlings grow up and get stronger, they will need to be cut into individual pots, reaching about 60 mm in diameter. Then they begin to gradually accustom them to the same care that an adult plant needs. After 12 months, the plants will need to be transferred to larger pots (20-30 mm larger in diameter than the previous ones).

Reproduction by a segment of the trunk

Since such a plant grows very much at home, it is propagated by a piece of the trunk, if there is such a need. In the summer, several parts must be cut off from the trunk, while in length they must reach more than 20 centimeters. Sections are planted for rooting in a slightly moistened soil mixture consisting of peat and sand, while the cut should be at the bottom. Then the box is transferred outside to a shaded place. On the parent bush, all the places of the cuts are covered with garden var. The planted sections must be covered with a film on top, it will help maintain the required level of air humidity, while the air temperature should be from 20 to 24 degrees. Make sure that the soil mixture is slightly damp at all times. Rooting of the segments will occur after 4–8 weeks.

Home plants. Part 1.

Cuttings

For reproduction of such a plant, apical cuttings are also used. Using a very sharp tool, cut off the top of the plant, while the cuts are treated with charcoal powder. The cutting should be left in the open air for 2 hours so that the cut sites have time to dry out. Then it is planted for rooting in moistened sand or placed in a container with boiled water. When rooting cuttings in water, a piece of charcoal is placed in a container, it should protect the cuttings from bacteria. Before the roots appear, rot may appear on the lower leaf plates. If this happens, then the leaves are removed, and the water in the container is changed. After the roots grow, the cutting is planted in a pot filled with soil mixture.

Possible problems

  • Yucca turns yellow... When the lower leaf plates turn yellow in yucca, you should not be intimidated, as this is a natural process. The fact is that green leaf plates can be found only at the top of the bush. The unusual appearance of such a plant is due precisely to the fact that it sheds the lower leaf plates.
  • Leaves fall... If part of the foliage flew around after the flower was bought and brought home or after transplantation, then this is his quite expected reaction to a change in the usual conditions. In the event that the foliage flies around in large quantities, then this may be due to hypothermia of the plant or to the fact that it was exposed to a draft.
  • Leaf tips dry and turn brown... Due to the extremely low air humidity, the tips, as well as the edge of the sheet plates, dry out and turn brown. It can also happen due to a draft or due to excessively rare or poor watering.
  • Brown spots on the leaves... If brown spots form on the plate, this indicates that the clod of earth in the pot is dry.
  • Leaves curl... If the room is very cold, then the edge of the foliage turns brown, and the plates themselves curl. In especially delicate species, this can happen if it is cold at night and you forget to remove the flower from the windowsill.
  • Spots on foliage... Sometimes, due to the scorching sun rays, dry spots of a light color are formed on the surface of the leaf plates.
  • Harmful insects... The plant is most often occupied by such pests as: whitefly, spider mites, scale insects and mealybugs.

Types of yucca with photos and names

Yucca aloifolia

In nature, this species is found in Jamaica, Central America, Bermuda, and also in the south of North America. The plant is extremely slow growing, but in height it can reach about 8 meters. The tree-like stem in adult plants is highly branching. Rosettes with fibrous foliage are formed on the tops of the branches. The length of the lanceolate leaf plates is about 50 centimeters, they are dark green with a spike at the top and with a serrated edge. In an adult bush, flowering is observed in the summer, at which time a paniculate inflorescence is formed, reaching half a meter in length. It grows out of a rosette and includes many bell-shaped flowers in its composition, reaching 30 mm in diameter, they are painted in a whitish-cream shade with a purple tint.

Yucca whipplei

In nature, this bushy, slow-growing plant is found in California, Mexico and Arizona. Its stem is short, and rigid and fibrous leaf plates are collected in rosettes, which reach about 100 cm in diameter.The leathery greenish-gray foliage of a lanceolate shape is about 100 cm long, has a thorn at the top, and teeth along the edge. The inflorescence of this species is practically the same as that of the aloe-leaf yucca, only it is longer (about 200 cm), and the flowers of the same color have a pleasant smell and are 5 mm larger. When flowering ends, the rosette dies off, and many shoots form at the base of the plant.

Yucca beak (Yucca rostrata)

The plate narrows to the base, its top is pointed, there are small grooves. The narrow white edges of the foliage are covered with a large number of fine threads. The length of the inflorescence is about 2 meters, at the top of it there are flowers collected in a panicle.

Yucca filamentosa

This plant comes from the east of North America. Its stem is practically absent. The root system goes into the deep layers of the soil. Such a plant is capable of growing strongly due to root suckers. It can withstand a short-term temperature drop down to minus 20 degrees. The leaf plates pointed at the top have a greenish-bluish color, along the edge they are densely pubescent with thin curly white threads. The foliage is about 0.7 m long and up to 40 mm wide. To get viable seeds, the plant must be artificially pollinated. On a two-meter peduncle, a lot of drooping eight-centimeter flowers of a yellowish-white color are formed. After flowering, the fruit is formed - a rounded box.

Yucca lipped-leaved (Yucca recurvifolia)

The trunk of such a plant is short (height is about half a meter), in some cases it is highly branching. At its top, rigid fibrous sheet plates are assembled into a rosette. The grayish-green drooping foliage, leathery to the touch, has a lanceolate shape and is about 100 cm long, has a thorn at the top, and a jagged edge.

Yucca glauca

Such an evergreen plant reaches a height of about 200 cm, and is native to the western United States. Its stem is short. Meter rosettes consist of densely packed leathery fibrous foliage. Lanceolate bluish-green leaf plates with a white edge are about 0.6 m long. The edge can also be gray with peeling fibers. In adult plants, in summer, a panicle-shaped inflorescence grows from the rosette, reaching a height of up to 100 cm. It consists of many bell-shaped flowers of a creamy white hue.

Yucca gloriosa

Densely growing dark green leafy plates, leathery to the touch, have a length of about 30 centimeters, and a width of up to 3 centimeters, their edge is covered with threads. During flowering, a branched, hanging two-meter inflorescence is formed, which consists of a large number of cream-colored flowers.

YUKKA! Pruning, grafting, planting in a Zeoflora capsule!


Yucca is unpretentious; a bright room is required for its maintenance. The yellowing of the leaves and their pallor are most often explained by a lack of lighting. The optimal daylight hours are about 16 hours, regardless of the season. In the cold season, it is better to illuminate the yucca with fluorescent lamps.

The temperature is needed moderate - from 15 to 25 ° C in summer, in winter it is recommended to provide the yucca with a cool content at + 3-5 ° C, but it will not die in a room. From the beginning of autumn, it is important to protect the plant from drafts, which can cause soft areas on the stem and leaves.

Sudden changes in temperature and humidity, as well as changes in conditions of detention, for example, when moving, can lead to peeling of the bark and shedding of leaves. However, with the further correct maintenance, this will not interfere with the normal growth of the plant.

If the smell of rotting comes from the bark, the leaves droop and become soft, then the temperature regime has been violated and an urgent need to carry out restorative procedures. In this case, you should transplant into fresh soil, remove the damaged parts of the root, dry the sections and treat them with charcoal.


Common types

As noted above, about thirty varieties of yucca are known, some of which are grown as indoor plants. The most popular are:

  1. Yucca is elephant. Caring for the plant at home will not cause any special problems, since it is highly unpretentious and has strong immunity. The table is powerful, it can reach a height of up to 1.5 meters. The leaves are palm-shaped and grow to a length of 75 centimeters.
  2. Aloe yucca. A perennial plant with an erect shoot and a lush spherical crown. A characteristic feature of the species is the olive elliptical-lanceolate leaves, located on the trunk in a spiral. Their length can reach 55 centimeters.
  3. Filamentous yucca. A unique variety with virtually no stem. Its long, pointed leaves grow directly from the roots. The rhizome is well developed and deeply embedded in the soil, thanks to which the shrubs are able to withstand even severe frosts, which greatly simplifies the care of the yucca at home. Leaves with a sharply pointed soft or hard top are blue-green in color and complex shape, and also reach a length of 70 centimeters.
  4. Gray yucca. In this variety, the stems are completely absent. Leaves are linear, with sparse, thin, curled filaments along the edge, have a bluish-green color and grow up to 70 centimeters.

Yucca (home care and transplantation will be described in detail later) is a perennial plant that differs from other members of the family in high endurance and good health. Breeding it does not cause any particular problems, so even novice growers will be able to cope with everything. With a little effort, you can grow an incredibly beautiful exotic plant that will diversify the interior and make it more cozy and attractive.


Yucca pruning

Yucca grows very slowly and rarely, if ever, needs pruning. Although they grow at a minimal rate, they become very large in both height and width, so you should be prepared for this when growing yucca indoors. If the plant grows too large, you can reduce the frequency of replanting by leaving three or four years between each replanting.

If the yucca is already taller than you would like, the only option is to trim off some of the height. To do this, you will need to saw off the main trunk, reducing it to a size that suits you. A little unattractive stump will remain, but over time, new shoots will grow from it. Do this with caution, in some cases pruning the yucca is an injury that the plant cannot recover from.


Pests

In addition to diseases, garden yucca can be damaged by insects. If the bushes have good immunity, then they are not afraid of pests. Damaged plants become targets for insects.

  1. Mealybug... Most often appears during a period when the plant is under stress from temperature changes. Outwardly, it looks like cotton balls. The worm is harmful to bushes, it feeds on the sap of leaves and branches, and multiplies very quickly. Getting rid of the worm is quite difficult. It is necessary to wipe the leaves with a sponge soaked in soapy water. In the end, you need to treat the bushes with an insecticide.
  2. Shield... Another dangerous pest that can destroy flowers. He looks like a little turtle. Attaches to the leaves and sucks out all the juices. If sticky discharge appeared on the bushes, then the scabbard made itself felt. Getting rid of insects is difficult. To begin with, you should remove adults with a sponge dipped in vodka. And then treat the bushes with an insecticide. You can repeat the procedure three times.
  3. Spider mite... On plants with weakened immunity, it will be possible to notice a spider mite. First, light spots appear on the back of the leaves, then a cobweb forms. Insecticides such as Fitoverm and Vertimek will help protect flowers.

Proper care is what is needed for the normal development of the bushes. If all activities are carried out in a timely manner, then the yucca will not hurt, and will soon delight the summer resident with stunning flowering. The flower bed will be transformed before our eyes, it will become a cozy corner on the site.
