Height

. The stems of indoor Hoya reach a length of 3 m and grow quickly.

Temperature conditions

. Choose a room with a normal room temperature of 18 – 22° C to grow the plant throughout the year. In the winter months, the room temperature should not fall below 10 - 12 ° C. A cool dormant period is not a prerequisite, but is desirable for the onset of flowering.

Growing Hoya - Lighting

. These plants require a lot of sunlight to develop properly. If they grow in poorly lit areas, they become thin and develop less colorful flowers. Direct sun can burn the foliage. Variegated varieties require brighter lighting than green varieties. When grown in partial shade, the leaf color often becomes dark.

How to care for pruning Hoya

. If you create favorable conditions for your hoya, then in the summer on a sunny windowsill it will bloom with beautiful, large inflorescences. After flowering, do not cut the flower stems - next year new flowers will appear on them again. Provide vertical support for the plant or wrap the stems around a rounded trellis.

Soil for hoya

. You need very porous, well-drained soil with a slightly acidic pH. As a top layer, it is better to surround the caudex with small pebbles or coarse sand to avoid rotting.

Fertilizer for hoya

. When growing, use fertilizers with a high potassium content (or balanced), feed every 2 weeks, the plants respond well to feeding! During the dormant period, feeding is stopped.

Purpose

. Great for both vertical gardening and hanging pots.

Hoya flowering time

. Flowering lasts throughout the summer, but occurs only with proper care.

Air humidity

. High, regular spraying is required.

Watering

. In spring and summer, watering should be plentiful, but between them the soil should dry out to a depth of several centimeters. The indoor plant Hoya easily tolerates short-term drought, but will not tolerate stagnant moisture in the soil. If the flower grows in a warm room where the temperature is above 15 C, it should be watered regularly, even during the winter months. When kept cool, Hoya should be in almost dry soil.

general information

Hoya is a genus of evergreen tropical vegetation consisting of vines and shrubs. It belongs to the subfamily Lastovnevye, the Kutrovye family, and the natural habitat of representatives of the genus is the territory of South and Southeast Asia, the western coastal zone of Australia and Polynesia.

The scientific name of the genus is associated with the English gardener Thomas Hoy, who worked in the greenhouses of the Duke of Northumberland, where he grew a variety of vegetation, primarily tropical. It was named after him.

The type specimen of Hoya obovata was discovered on the island of Butung, located near the southeastern part of Sulawesi (Indonesia). This vine can also be found in the flora of Indonesia (Sulawesi), India, Thailand and Fiji.

Description

Obovata is a vine that has climbing shoots and grows quickly:

• It has thick, fleshy foliage, round in shape, without noticeable veins.
• The color of the leaf blades is rich green, with light specks randomly located on the main background. There is a form of Hoya obovata - splash, the leaves of which are abundantly covered with splashes and variegata - the center of the plate is much lighter.
• Foliage diameter – 6-8 cm.
• In abundant light, obovata blooms luxuriously, and it produces umbrellas consisting of 2-3 dozen star-shaped flowers. They are fluffy, soft pink, with a dark crown in the center - pink or dark pink.
• The main flowering time is late spring.

Like other hoyas, obovata produces a large amount of nectar, only it is not dark in color, but colorless.

The flowers are fragrant, their aroma is sweetish, honey, with a slight echo of a fresh cut of radish. The smell intensifies noticeably at night.

A number of researchers believe that Hoya obovata is a hybrid species obtained by crossing Hoya carnosa and Hoya kerry.

Description of Hoya Obovata species with photos

Variegata

The flower grows and develops very quickly . The stems are large, climb well, and over time acquire a light brown tint. The leaves are large, lobed, light green, with a wide yellow-green stripe in the middle of the leaf. The leaves are voluminous in shape, round, dense, shiny, up to 8 – 9 cm in diameter.

Additional leaves are light green, covered with a silver scattering of small spots. The flower itself is two-tiered, the base is milky white, the crown is bright crimson. The main petals are pointed, slightly curled down, the crown has the shape of a five-pointed star.

On a note! The variegated variety of the flower has a tart, sweetish aroma, produces transparent nectar, and blooms quickly in May - early June.

With proper care, flowering continues for several months. Shape-forming pruning is required. Propagated in most cases by cuttings.

Splash

The variety is very popular and does not grow very quickly. The stems are long and require support to maintain the integrity of the root system . The stems are up to 0.5 cm in diameter, at the very beginning the shoots are reddish in color, then they acquire a woody structure and a brown tint.

The leaves are thick, dense, fleshy, shiny, round in shape, up to 6–8 cm in diameter. The leaf plate is covered with silver spots - stains, the leaf veins are practically not visible. The inflorescences are lush, rounded in shape, containing 25 - 30 small flowers.

The flowers are five-pointed, the petals are pointed, pale pink. The crown of the flower is darker - a rich pink - crimson hue. The flowers have a distinct sweet aroma. Blooms profusely in late spring.

Important! Regular pruning of stems is required.

To preserve variegated foliage, bright lighting without direct sunlight is required .

Features of the care and maintenance of hoya are obovovat

The liana is unpretentious, however, we must not forget about its exotic origin and climatic preferences. The owner should take care of the following aspects:

Suitable soil mixture

The substrate should be light, nutritious, and well-permeable to water and air. You can purchase it at a flower shop or prepare it yourself by mixing the following products:

• 1 part of turf land.
• 1 part leaf soil.
• 4 parts peat.
• 1 part sand.
• 1 part humus.

You should definitely place drainage material at the bottom of the pot - sand with expanded clay, clay shards, brick chips, vermiculite, agroperlite. In extreme cases, pieces of foam plastic can be used for these purposes. Drainage will not allow moisture to stagnate at the root system of the flower and eliminate the likelihood of it rotting.

Temperature

Hoya obovata is a heat-loving plant that does not tolerate drafts and sudden temperature changes. In summer, the optimal indicator should vary in the range of +18 - +25 degrees; in hot weather it is recommended to spray the flower regularly.

In autumn and winter, obovata prefers to rest in the cool air. This means that, starting in autumn, the room temperature should be gradually lowered to a stable level of +12 to +15 degrees. It should not be allowed to drop to +10 degrees; such cold is destructive for obovata.

Watering mode

All hoyas need moisture constantly, regardless of the season. You can adhere to the following recommendations:

• Water the obovata when the top layer of the soil mixture dries out.
• In the warm season, water is added regularly, but little by little, and the foliage of the vine is also sprayed once a day.
• It is recommended to wipe the hoya leaves weekly with a soft, damp cloth.
• Purified or settled water is used, at room temperature. If it is hard, then it is advisable to soften it by adding sphagnum moss, charcoal or activated carbon.

Lighting requirements

Light is necessary, but it is desirable that it be diffused. If the vine is located on a south window, then in summer it should be shaded, protecting it from direct sun. Otherwise, the foliage may lose its brightness, become covered with burns or brown pigmentation.

This flower has a negative attitude towards change, both movement and sudden changes in light conditions. This may cause the plant to stop flowering or lose its leaves.

Trimming

It is recommended to cut off vines that are too long. This should be done with a disinfected instrument. The best time for the procedure is March. And since obovata is a fast-growing flower, you will have to trim the shoots and pinch out new shoots every year.

After the event, the plant acquires lateral buds, the bush becomes thicker and blooms more luxuriously.

But you shouldn’t touch the peduncle, as new inflorescences appear on it.

How and what to feed obovata?

The flower is fertilized during the active growing season, when it grows and blooms - from early spring to late summer. 2 times a month is enough.

Complex mineral mixtures are suitable for these purposes. Blooming Hoya can be fed with a nutrient solution for flowering succulents, just dilute it in more water.

Landing Features

Several seedlings can be planted in one container; they form a dense, beautiful shrub. Long stems require additional support so that the root system is not damaged under the weight of the heavy above-ground part of the plant.

Care

Temperature

The variety is heat-loving and does not tolerate drafts and sudden temperature changes . In summer, the optimal temperature is 18 – 25°C. To reduce air temperature and increase humidity, regular spraying is required. In the autumn-winter period, Hoya Obovata enters a dormant state, the optimal temperature is 12 - 15 °C.

Avoid overcooling the flower; temperatures below 10°C are detrimental to this variety.

Watering

The soil should not be allowed to dry out even in winter . Watering should be done after the top layer of the substrate has dried. In summer, regular watering in small doses is required, preferably daily spraying, once a week the leaves should be wiped from dust with a damp swab.

Note! Watering should be done with warm, purified or settled water. To reduce water hardness, add a little sphagnum moss to the water.

Light

Hoya Obovata prefers bright places, but in summer, southern windows should be shaded so that direct sunlight does not fall on the leaves.

Excess light causes the leaf plate to lose its brightness, and burns and pigmented brown spots may appear. Also, the flower does not like frequent movements or changes in light conditions; exotic flowers can stop flowering or shed leaves.

Trimming

For good growth, the plant necessarily requires pruning of long stems .
The procedure is usually carried out in early spring. Hoya Obovata grows quite quickly; this variety requires annual renewal - pruning and pinching new shoots.

After trimming the long stems, lateral buds appear, the flower becomes thicker, the flowering is more lush and bright.

It is not recommended to remove the peduncle itself ; new inflorescences develop on it.

Feeding

During growth and flowering, Hoya Obovata needs to be fed with complex mineral fertilizers. Typically, fertilizers are used for blooming succulent flowers. From March to the end of August, regular fertilizing is applied once every 2 weeks. Fertilizers are added to water for irrigation. When using universal fertilizers, the dosage must be strictly observed, especially for young flowers.

Pot

Pots, flowerpots, hanging flowerpots should not be too large; drainage holes should be made to allow excess water to drain out and air to enter. Before planting, the pots are treated with boiling water or other disinfectants. A drainage layer must be laid on the bottom - broken brick, expanded clay or pebbles.

Important! Several seedlings are usually planted in one pot for density. Long stems must have strengthening support so that the roots are not damaged by the weight of the voluminous stems.

How to propagate Hoya obovata at home?

There are several methods for propagating tropical vines at home, and each of them has both its advantages and disadvantages.

Planting seeds

Gardeners usually do not use this method for growing indoor Hoya obovata. They resort to it when growing vines in greenhouses, where there is a humid microclimate suitable for sowing. The sowing process is as follows:

• The seeds are dried in air.
• Burlap or some artificial fibers are added to the soil.
• Within a week to a week and a half, the seeds germinate.

Growing methods

Seeds

Note! Growing Hoya Obovat in an apartment is not practiced by gardeners.

In wet greenhouses, the variety is propagated by seed sowing in the spring.

Seed planting procedure:

1. The seeds are dried.
2. Burlap or artificial fibers are added to the soil.
3. Within 7–10 days, the seeds germinate.
4. Seedlings are kept warm; additional lighting and regular watering are required.
5. Seedlings are grown for up to 3 months.
6. When several leaves appear, the seedlings are transplanted into pots.

Seed viability is 1 year.

Leaf

Hoya Obowata is grown with leaves, but the effectiveness of this method is quite low . The process is lengthy; leaves only from natural mother varieties are required. Leaf propagation process:

1. The sections are treated with a rooting agent.
2. The leaf must retain its petiole.
3. Leaves are planted in a light substrate at an angle of 45°
4. Good lighting is required.
5. The temperature of the sprout is up to 22° C.

Cuttings

Hoya Obowata is propagated at home only by cuttings . The reproduction procedure is simple:

1. 
   Cuttings of 4–5 cm are cut.

2. Cuttings that have leaves and nodes are used.
3. The pot is wrapped in foil - during germination, light should not enter the substrate.
4. The cuttings are treated with a root growth stimulator and lowered into a sandy substrate.
5. The pot is transferred to a warm place – 22 – 24°C.
6. For a greenhouse effect, the seedlings are covered with foil.
7. After 2 weeks, roots appear.

Important! You should not overexpose the cuttings in the substrate - roots that have grown too long are brittle, brittle, and easily damaged when transplanted into the ground. The flower takes a long time to adapt and may get sick. When replanting, it is important to preserve the earthen ball.

You can use a simpler method of reproduction:

1. It is necessary to place the cuttings in a dark, non-transparent container.
2. Place in a warm place – temperature up to 25°C.
3. Irrigate daily with a fine mist.
4. You can add root hormone to the water.

Root germination occurs after 10 – 12 days.

Composition of the substrate for Hoya Obovata:

• Turf soil – 1 hour.
• Leaf soil - 1 tsp.
• Peat – 4 hours.
• Sand – 1 hour.
• Humus – 1 hour.
• Drainage - a mixture of sand, expanded clay, clay shards.

Diseases and pests are common

Most of all, the vine is afraid of stagnant water and waterlogging of the soil. These maintenance violations can lead to the development of root and stem rot. The flower is especially vulnerable during the winter holidays; excess moisture against the background of cold can greatly harm it.

Hoya can be cured of these fungal diseases using fungicidal drugs.

To prevent fungus and other infections, it is recommended to periodically treat the soil and foliage with a solution of Bordeaux mixture. In summer, you can bathe the obovata under a warm shower and then remove excess moisture. Hoya obovata can be affected by scale insects, spider mites, whiteflies or aphids. They are removed manually, the foliage is treated with a solution of laundry soap or diluted alcohol. In case of severe damage, the use of insecticides will be required.

Diseases and pests

Improper care weakens the plant and can be affected by bacterial and fungal infections.

In such cases, treatment with fungicides , such as Bordeaux mixture, helps.

As a preventive measure, it is recommended to wash the leaves in the shower and optimize the living conditions.

Red spider mites, aphids, and scale insects settle on insufficiently cared for specimens As a first aid solution, a soap solution or cotton wool soaked in alcohol is used to remove pests. Only systemic insecticides can completely get rid of them.

Give it a permanent bright place, provide it with a cool winter, do not over-water it, prune it in a timely manner - and it will grow quickly, produce new glossy round leaves and bloom regularly, exuding one of those unusual aromas that the distant jungle smells of.

2. Hoya care at home

2.1.Reproduction

Most often, vegetative propagation or cuttings .

Propagated by stem cuttings 8–10 cm long , each of them should have two pairs of leaves.

1. The bases of the cuttings are rinsed with running water to remove any released juice.
2. The cuttings in the lower part are dusted with rooting powder.
3. To reduce moisture loss, remove the lower leaves.
4. For planting, prepare small cups or pots with drainage holes.
5. A drainage layer about 3 cm high is placed at the bottom of the pots.
6. Fill the containers with nutritious and loose substrate.
7. The bases of the cuttings are immersed in well-moistened soil with a high sand content. Instead of soil, you can use moistened perlite or vermiculite.
8. Young plants are placed in a warm and well-lit place without access to direct sunlight under a cover made of transparent plastic or polyethylene.

The first roots can be noticed within a few days, and at a temperature of about 20°C, rooting will take 1.5 - 2 months .

The tops of young plants are pinched 4 leaves appear .

Plants obtained from cuttings will bloom only at the age of 4 years .

You can root Hoya cuttings even in a glass of water .

Leaf cuttings can also be used for vegetative propagation . For this method, the leaf is separated from the mother plant along with the petiole and the base of the petiole is dusted with growth hormones.

Leaf cuttings take longer to root than stem cuttings.

Rooting also takes place successfully in plain water, but plants that are then planted in the ground experience stress from sudden changes in conditions and are inhibited in growth.

by air layering works well ; for this, the long stems of the plant are pinned to the surface of the soil and lightly sprinkled with soil. The top of the shoot should be above the ground.

After some time, roots will appear in the leaf node. The successful completion of the rooting process will be indicated by the appearance of new growth.

Young cuttings are separated from the mother plant when they have already formed a good root system and have a sufficiently developed above-ground part.

Small plants are planted in cramped pots - in such conditions they develop faster and are less likely to rot. Several such transplants will be required for each plant.

You can get hoya from seeds , but for this you will have to be patient; in addition, only fresh planting material has good germination.

Seeds are sown in spring using a transparent plastic container with a lid.

1. Drainage holes are made at the bottom of the container.
2. The first layer is laid out with expanded clay drainage.
3. Fill the container with a loose and nutritious, light substrate - a mixture of peat and river sand in equal quantities is suitable.
4. The soil is well moistened from a spray bottle with water at room temperature.
5. Containers with seedlings are kept in a warm place, shaded from direct sunlight.
6. The container with seeds is covered with a lid to maintain uniformly high air humidity.

In such greenhouse conditions, the first shoots can be noticed within 1 - 2 weeks .

With the appearance of the first shoots, the cover is removed daily for a few minutes and condensation is removed from it. Gradually, the ventilation time is increased, hardening the seedlings.

Young plants develop rather slowly.

Picking into separate cups is carried out with the appearance of the first true leaves - when the seedlings are about 3 months .
