In the first year after transplanting, it is better to cut out all the buds, flowering can weaken the fragile root of the transplanted bush.

In snowless winters in cold climates, mulching is required and shelter for the winter bushes with coniferous branches or burlap.

Mulch is updated every spring around the base with a layer of 5 - 7 cm.

Breeding

Propagated by layering or cuttings.

Propagation by cuttings is carried out in July - August:

1. Cuttings of 6 - 7 cm are cut.
2. Planting processes are soaked for 12 hours in a solution of a growth stimulator.
3. Cuttings are planted in small boxes in a sand - peat mixture, covered with a film or glass.
4. Aeration of greenhouses regularly - 2 - 3 times a day.
5. After 4 weeks, the cuttings will take root.
6. In autumn, seedlings are transferred to the cellar, where they grow up until next spring.
7. The grown seedlings are planted in open ground in the garden or in large boxes.

Reproduction by layering is a simple procedure that does not require much effort:

1. Choose a branch that grows low to the ground.
2. An incision is made on the stem.
3. Lay the branch in a small hole, fix it with hooks from the wire, and add it.
4. When the shoot takes root, the bush is separated.

Diseases and Pests

• A mealybug, a rhododendral bug and a weevil can attack the Rhododendron Blumbux. Timely spraying with insecticides is necessary - actar or phytoerm. If the damage is strong, the treatment is repeated after 10 days.
• They attack bushes and garden snails and slugs, they are usually collected manually.
• A soap solution will help get rid of the spider mite. It can be sprayed with a fungicide solution. Usually, a single treatment is sufficient to kill the pest.

TIP! It is better to change drugs from time to time to exclude parasites from getting used to them.

Prevention of various problems

• Problems usually arise from dampness, waterlogging of the soil, improper doses of fertilizers or fungal diseases.
• Due to the sun or insufficient watering, leaves and stems may turn brown - watering needs to be adjusted.
• Damaged leaves should be collected, diseased stems cut, sometimes, when the flowers are completely infected, culling of the bush is required. By collecting and burning damaged foliage, performing sanitary pruning and treating plants with fungicides, many diseases and problems can be avoided.

For the prevention of diseases and the appearance of pests, it is necessary to treat the bushes with Bordeaux liquid in late autumn and early spring , before the appearance of bees and insects - pollinators.
