Features of flowering indoor rhododendron

Blooming azalea will leave few people indifferent. This beauty blooms in winter, when it is cloudy, sad and so you want warmth and colors. The whole bush covered with inflorescences looks like an elegant festive bouquet.

The duration of flowering depends on the room temperature:

  • at +12 azalea can bloom for more than two months;
  • at +20 - only two weeks.

When to expect the buds to appear?

If you choose the right azalea varieties, you can enjoy flowering from November to May:

  • early flowering varieties bloom in November-January;
  • medium flowering in January-March;
  • late blooming - from February to April.

Prerequisites for a set of buds

Getting a chic flowering bush is not easy. In order for the azalea to bloom, it is necessary to provide it with comfortable conditions:

  1. lighting;
  2. room temperature;
  3. correct watering.

The best place in an apartment for an alpine rose is east and west windows. She doesn't like direct sunlight. In winter, it is advisable to use additional lighting to increase daylight hours.

During the budding period (starting in September), it is ideal to keep the pot on a glassed-in balcony or loggia at temperatures from +5 to +8 degrees. Water in moderation.

Important! Azalea lays flower buds in the autumn-winter period, at this time it must be kept in a bright, cool room at a temperature not higher than +8 degrees.

When the first buds appear, the plant can be transferred to a warmer place.

After the end of the flowering azalea, you need rest to gain strength for the new season. At this time, pruning, pinching, feeding are carried out, watering is reduced.

Alpine rose loves abundant watering, preferably with settled water or rainwater with a low lime content. The ground should be slightly damp all the time.

Azalea absolutely does not tolerate stagnant water in a pot, the roots may begin to rot and the flower will die.

When planting, be sure to use drainage. Make sure that no water accumulates in the pan after watering.

Why doesn't it bloom?

If a year has passed, and the rhododendron has not bloomed for some reason, we must try to understand why there are no buds for so long.

Improper care

  • High room temperature. Azalea does not like warm dry air, especially if there is a battery next to it.
  • Lack of lighting.
  • Direct sunlight.
  • Watering with warm water or water directly from the tap.
  • Lack of moisture in the soil. Dried earth is death for the plant.
  • Pruning the bush during bud formation.
  • A large number of young shoots take away the strength from the flower.
  • The presence of drafts.
  • Small or too large pot size. In the first case, the plant cannot develop. In the second, the roots grow vigorously and the azalea does not have the strength to bloom.

Diseases and pests

A capricious beauty often suffers from fungal and viral diseases. (all kinds of mosaics, alternaria, etc.) They appear when:

  • violation of the irrigation regime and temperature;
  • improper lighting;
  • low air humidity.

Reference. For the prevention of diseases, it is recommended to spray a 1% solution of Bordeaux liquid over the bush every 10-12 days.

Azaleas and pests can annoy:

  1. aphid;
  2. spider mites;
  3. azalea moths.

In the fight against them, spraying with a 0.15% solution of Actellik or rubbing the leaves with a soapy sponge is well suited.

We offer you to get acquainted with the possible pests of azaleas and how to deal with them:

Is it possible and necessary to stimulate the process?

Azalea blooms can and should be stimulated. For this, the plant is given a special feeding:

  • during the period of bud formation, fertilizers containing phosphorus and potassium are used;
  • to accelerate flowering - special fertilizer azalea, zircon;
  • after flowering, for rest and development of the plant - fertilizers containing more nitrogen (Uniflor-micro).

Reference. Experienced flower growers, in order to make the azalea bloom profusely, water it with very cold water and even spread dry ice around the pot.

What to do to make the rhododendron bloom?

If the azalea does not bloom, do not get upset ahead of time and assume that the flower is gone.

Following our instructions, you will return the plant to a normal rhythm of life and the result will not be long in coming.

Changing care conditions

Consider how to care for a potted plant so that it begins to bloom:

  1. In mid-September, transfer the plant to a cool, bright room with a temperature of +5 - +8 degrees and reduce watering to moderate. Soon, new buds will appear on the tops of the branches.
  2. In winter, when the buds begin to swell, the azalea can be transferred to a warmer room with temperatures up to +20 degrees. At this time, watering must be increased.
  3. After flowering and until mid-May, keep the alpine rose in a cool room. Reduce watering and do not fertilize. Azaleas need to be given a rest and gain strength.
  4. In summer, it is advisable to take the flower to a shady part of the garden or to the balcony, increase watering, fertilize once every 2-3 weeks
  5. Make sure that the soil in the pot is constantly slightly damp. But don't fill the flower. The water must not stagnate.

Pruning and pinching

It is important to do the pruning and pinching of the azalea on time and correctly. They influence the future formation of buds and the splendor of the inflorescences.

After the end of flowering:

  1. remove wilted flowers;
  2. prune all dried, weak, overgrown shoots and shoots near the buds;
  3. it is better to pinch young shoots to form a beautiful bush.

Attention! Azaleas can be pruned until mid-June. But not later. At this time, the formation of already new flower buds begins. And cutting them can damage them.

If suddenly full-fledged buds appear in azaleas in the summer months, professionals advise to pinch them. They take away the strength from the plant and still will not bloom.

We suggest that you familiarize yourself with the rules for pruning and pinching an azalea:

Top dressing

Azalea loves mineral fertilizers, which contain phosphorus and potassium:

  • During the post-flowering period from May to June, feed the plant with fertilizers containing nitrogen. It promotes the growth and development of the flower. Sprays - antistress elin and HB-101 are also well suited.
  • During the period of azalea growth and flower buds (from June to September), feed the plant once a week with a complex fertilizer for azaleas or flowering plants.
  • During the budding period (from September to the beginning of flowering), zircon will be the best fertilizer. It stimulates flowering. And it is a good tool for building and growing roots.

Reference. During the flowering period of azaleas, it is forbidden to use sprays. Top dressing is not recommended.


If the azalea grows in a pot that is too small, in the spring after flowering, transplant it into a pot about 5 cm higher than the previous one.

Alpine rose loves loose, acidic soil. Special azalea mixes or heather substrates work well.

We suggest that you familiarize yourself with the rules for transplanting an azalea:
