Location and Lighting

A pot with hoya is best placed on the southern windowsill, as this flower is photophilous. Thus, you will provide the plant with the desired level of lighting. But keep in mind that direct sunlight adversely affects the hoya, so they should be avoided. With insufficient lighting, the hoya will not bloom.

Important! Do not change the location of the hoya and do not rotate it after the buds appear, because it will reset them. Protect the plant from drafts.

Temperature and humidity

In the summer, the room temperature (+20 ... + 25 ° С) is quite suitable. In winter, you need to lower the room temperature for the flower to + 15 ° C. Hoya needs high humidity (80% and higher). This is due to the fact that the plant in the wild lives in areas with a humid climate. To increase humidity, it is helpful to spray the hoya. This should be done so that water does not fall on the buds and flowers.

Home Care

Hoya is unpretentious in leaving. But still you need to know the basic recommendations that will allow the plant to grow and develop well.


Hoya is poured with water at room temperature using the root method. In summer, the plant needs more water than at other times of the year, so watering should be plentiful, necessarily as the topsoil dries. In the cold season, watering should be reduced. Hoya tolerates a lack of moisture better than its excess.

Important! After watering, drain the water from the pan of the pot, otherwise the roots of the flower will begin to rot.

Fertilizer application

Hoya fertilizers must be applied throughout the year, except for winter. Once a month, use Osmokot top dressing. Spray the flower twice a month with liquid humus, such as Biohumus. Use these products according to the instructions on the packaging.


Hoya carnose cannot be cut, as this will be stressful for the flower, because of which it can become sick. You can not even remove old peduncles. After a while, they will bloom again. Only damaged leaves can be removed.


It is recommended to transplant the hoya in April every 2-3 years, not more often, since frequent transplants are stress for the plant. Hoya is transplanted into a special soil consisting of leafy, soddy ground and humus (3: 2: 2). You can buy special soil for palm trees or add moss-sphagnum, crushed tree bark to the prepared soil.

Find out when you need to transplant indoor plants.

Hoya is transplanted into the pots. It should be slightly larger in diameter than the previous one. A plant begins to bloom only when the roots fill the entire pot. Hoya blooms profusely in a tight container. Too large a pot will slow this process down. Make sure that there is a drainage hole in the pot to let out excess moisture and allow oxygen to flow to the roots of the plant.

The flower is transplanted in the following sequence:

  1. First, carefully remove the plant from the old pot, tilting it slightly.
  2. Free the roots from the ground. See if they are healthy. Remove damaged parts.
  3. Fill most of the new tank with pre-prepared soil.
  4. Put the flower in a new pot.
  5. Pour the rest of the soil into it, ram it on top.
  6. Water the hoya and set it in a sunny place.


Propagate the plant using cuttings and seeds. Consider each of the methods in more detail.

For this, apical cuttings are used, which are cut at a level of 10-15 cm from the top. There should be several buds on the handle. To root a new plant, plant it in peat mixed with sand in a 1: 1 ratio. Moisten the soil. Keep a pot with a planted handle in a very warm place.

Important! The higher the temperature in the room, the faster the root will take root.

Another way is to place the stalk in water and put in a warm place. After about two weeks, roots will appear. Having noticed them, the cuttings are immediately planted in the soil.

Seed cultivation

Hoya seeds resemble dandelion seeds. They need to be collected from flowers and dried. After that, the seeds are planted in the same soil as the cuttings. To seed quickly sprouted, put the pot with them in a warm place. Water the soil regularly as soon as its top layer dries. At the same time, avoid waterlogging of the substrate.

After 3 months, healthy plants are selected from all seedlings and planted in a separate container. You can sow the seeds also in moistened sphagnum moss, wrapped in a nylon net and placed in a warm place. In this case, the seeds will sprout faster. As soon as they germinate, small plants are planted with a moss in a pot.

Growing difficulties

During the cultivation of hoya, flower growers may encounter difficulties that are represented by diseases and pests:

  1. Fungus. You can get rid of it by spraying the plant with a 1% solution of Bordeaux fluid. For prevention, wash the hoya regularly in the shower.
  2. Thrips and scale insects. You can get rid of pests with the help of special drugs ("Doctor Foley", "Fitoverm", "Trichophytum"). They are used according to the instructions. As a preventative measure, wash the plant from time to time in the shower.
  3. Mold on the surface of the soil. Appears from excess moisture. In this case, reduce watering.
  4. Dark spots on the leaves. Appear as a result of exposure to the plant in direct sunlight, which should be avoided.
  5. Lack of flowers. This occurs when there is insufficient lighting, if the room temperature is too high in the winter, if the hoya grows in a very close pot and lacks nutrients. Find out the cause of the lack of flowering, and eliminate it.
  6. The leaves are dry. This is a sign of low humidity. It needs to be increased.
