The flowers themselves are like intricate bells or funnels with elegant rainbow stamens. Inflorescences can be voluminous, or 2 to 3 flowers can be collected, it all depends on the variety cultivated.

Differences from other species

The main feature of this species is blooming so large and plentiful that during flowering it turns into a flowering meadow, completely covered with bright colors, because of which leaves are not visible. In autumn, a wonderful metamorphosis with leaves begins - they turn into bright yellow, red, burgundy lights, transforming gardens and front gardens.

How to determine which subsort belongs?

First of all, deciduous rhododendrons are classified according to the color of the flowers:

• Yellow deciduous rhododendrons - these are hybrids of Klondike, Narcissiflora, Anneke, Glowing embers and other subsorts.
• Rhododendron Ghent - numerous hybrids - mixes have a wide variety of flowering colors.
• Pink - Homebush, Ghent subcategories.
• Reds - Nabucco, Kamchatsky and other sub-grades show varieties of the red color palette.

Features

The most important sign of deciduous rhododendron is its frost resistance. There are varieties that are best bred only in the southern climate, or for them a winter shelter is required. For example, the rare and finicky variety Narcissiflora or Anneke rhododendron, which does not tolerate frosts, requires protection - shelter.

There are more hardy varieties - Kamchatsky, Klondike and others. They perfectly tolerate both the sun and frost, easily adapt to any climate and take root in simple garden soils.

Growing conditions and care

Deciduous rhododendron is easy to handle and does not require too much effort. Tropical resident prefers partial shade. There are varieties that can only survive in the southern latitudes; they tolerate summer heat up to 30 ° C.

ATTENTION: In summer, daily watering and spraying. The procedure is preferably carried out in the early morning or after sunset. In winter and autumn, watering is reduced.

Watering should be on the entire surface of the substrate so that the roots are not washed out. In late autumn and winter, you can only water in dry weather. Deciduous rhododendrons must be sheltered in winter from frost and wind. It is advisable to mulch the soil around the root.

Hybrid species of deciduous rhododendron from northern varieties are more frost-resistant, they withstand a temperature drop of -25 ° C. In snowy winters, you can not close them. But mulching the soil is necessary. Fertilizing deciduous rhododendrons is necessary from the moment of flowering. Fertilizers should be intended only for acidic soils.

It is not recommended to feed and transplant deciduous rhododendron during kidney formation - there is a risk of shedding.

It is advisable to fertilize the substrate 1.5 to 2 months before the onset of frost. Almost all varieties of deciduous rhododendron are best covered for the winter, bending the branches to the soil so that the buds do not touch it, you need an air cushion. It is important in winter to make an outflow for incoming moisture in order to avoid dangerous snow ice.

In summer, garden weeds must be removed. Mulching is preferably carried out 2 times a year, adding small coniferous bark or fallen conifer needles. Such a shelter helps preserve the moisture of the substrate, preserves nutrients, and resists the growth of weeds. The mulch layer should be 5 - 6 cm thick. The root neck is usually covered with dry leaves, preferably oak.

Transplantation is carried out in early spring, can be transplanted before and after flowering.. When transplanting, the seedling is surrounded by a rim of moss and coniferous needles, 10 cm tall. Thus, snow is delayed, which protects the roots from freezing.

When and how to plant rhododendron?

When planting, acidic soil is used, consisting of peat and heather land. For planting, dig a deep half-meter hole with a diameter of 60 - 70 cm. Drainage is put at the bottom, 10 - 15 cm.

Half the pit is filled with moss - sphagnum, then filled with a mixture of loose soil and humus leaf. It is imperative to form a drain for excess accumulated water.

Breeding methods

1. Seeds. Deciduous rhododendrons reproduce by seed. Sowing is done in early spring. Germinate in a cool room at a temperature of 12 - 15 ° C. Seeds are sown in a sand - peat mixture, slightly pressing them. Moisturize regularly. When the first leaves appear on the sprouts, they are dived and placed in a small greenhouse, aired 2 times a day. Such seedlings bloom only for 5 - 6 years of cultivation.
2. Cuttings. This species can be propagated by cuttings. In the middle of summer. When the buds begin to be laid, cuttings are cut with a length of 7 - 9 cm, leaving 3 to 4 leaves on them.

When grafting at the top of the handle, leave leaves. Before planting, the cuttings are dipped for a day in a solution with any root growth stimulator. Then, for rooting, they are planted in a ready-made special substrate. Provide circulation of warm air from below - usually lift containers with cuttings on supports or on a bench.

Rhododendron seedlings take root very slowly. After rooting, such seedlings cannot be immediately planted in open ground. They should winter in a cellar or cool room with a temperature of 2 - 5 ° C. In the southern regions, you can plant directly in open ground, while a dry shelter is required, seedlings are still too weak and fragile to withstand wind and frost.

3. Layering. The easiest way to propagate deciduous rhododendron is layering. The procedure is carried out in early spring, using last year's shoots. They are instilled and fixed with wire, slingshots or hooks on the ground. The earth is moistened regularly all summer, watering a solution of a growth stimulator once every 3 to 4 weeks for better rooting. Young shoots are separated next fall. Flowering will occur 2 years after the separation of seedlings.
