Distinctive features
Based on the harsh conditions of its natural habitat, the shrub has some differences from its counterparts in appearance:
- Rhododendron Ledebour is resistant to severe frost. It easily tolerates winter frosts down to -32 degrees. But during the winter thaws, the plant quickly wakes up, so subsequent frosts can harm the already activated rhododendron.

Growing
The shrub is not picky about care, but there are points that must be considered when growing the Ledebour rhododendron.
Site and soil selection
For planting Ledebour seedlings in open ground, certain conditions are needed:
- The soil for seedlings is preferably stony, with a high acid content. It is in such a soil that rhododendron grows in its natural environment.
- He does not like winds and drafts, so the site for seedlings must be protected from them.
- For active flowering, the shrub needs sunlight, but the plant does not like direct rays. The land plot for planting a rhododendron should be slightly shaded.
- Plants with a deep equine system are chosen as neighbors of rhododendron. The roots of the shrub are close to the surface, so the same neighbors will become a great obstacle to the growth and development of the shrub.
- The plant grows well and develops on the shores of small bodies of water. It can be a decorative garden pond or a stream.
Important! Large inflorescences require additional sunlight on the plant.
Selection of seedlings and planting dates
Although the rhododendron is distinguished by its viability, the choice of planting material must be carefully and carefully. It is best to buy young seedlings in specialized nurseries or garden centers. There professional consultants will offer really healthy and robust plants.
To purchase planting materials at exhibitions, you must have the knowledge of an experienced gardener:
- A 2-3 year old seedling has a large number of dense shoots.
- Leaves without damage or knots. Also, they are free of spots, streaks and irregularities.
- The root system is not overdried, without nodules and damage.
- Low seedlings, 15-20 cm., A guarantee that they were grown in the open field, so the process of planting a young plant will be easier to transfer.
Plants grown in greenhouses are higher, but they get used to open ground more difficult and longer. The shrub is planted on the site in early spring or autumn, the main thing is that the work does not take place during the active flowering phase.
Planting
To plant the Ledebour rhododendron, a hole is pulled out to a depth of 50 cm, 60 cm in diameter, into which peat and clay are laid. Before planting, the seedling must be held in water for 2-3 hours, if the root system is overdried, then the period is increased to 10 hours.
The seedling is inserted into the hole, the root system is neatly laid out and sprinkled with soil mixture. There should be no empty land areas between the roots. The soil around the planted plant is compacted and watered abundantly.
Important! The shrub has thin roots that are close to the soil surface. Therefore, it is advisable to support young plants with supporting pegs before rooting..
Temperature
The shrub is distinguished by its frost-resistant qualities.He easily survives the winter at -32 degrees. But in extreme heat, rhododendron requires shading and additional moisture. Especially, the temperature regime is important when forming buds. During this period, the most comfortable temperature for the plant will be 15-17 degrees.
Watering
Ledebour's rhododendron is a moisture-loving plant, therefore irrigation work is carried out often. The flowering of a shrub directly depends on its watering. The first sign that the bush lacks moisture is withered, yellowed leaves.
Irrigation works are carried out with settled water. Also, to increase the acids in the soil, a little peat is added to the water. In drought and hot weather, it is advisable to shade the bush and spray it. Active watering of the shrub is necessary from spring to autumn; in the winter season, rhododendron is not watered.
Top dressing and loosening
The Ledebour rhododendron shrub, like other plants, needs additional feeding. Fertilize it from the first year of planting in open ground. In early spring, they are fed with organic fertilizers. Next, small doses of nitrogen and phosphate fertilizers are added. Mineral fertilizers are used with caution, because they sharply reduce the acidity of the soil.
The root system of the shrub is located close to the upper layers of the soil and suffers greatly from weeds, which take away moisture and nutrients from it.
Weed and loosen the soil under the bushes carefully, without damaging the roots of the plant. To protect the rhododendron from external influences and weeds, the soil is mulched with sawdust, pine needles or garden mulch.
Pruning
Rhododendron bushes are able to keep their beautiful shape for a long time on their own. Therefore, formative pruning is carried out as needed and only the central branches. But every spring and autumn, they do sanitary pruning of dried, broken and damaged branches.
Transfer

If it was not possible to transplant the plant in the spring, then the work is postponed to September or October. After transplanting, the plant will grow faster and gain new strength for vigorous flowering.
Wintering
Rhododendron tolerates mild winters down to -10 degrees. At such temperatures, the shrub does not need additional insulation. After snow falls, small drifts are created around the plant, which protect the rhizome from freezing. In regions with severe winters, the shrub is insulated with spruce branches or burlap. Warming is removed with the first spring thaws.

- When propagated by cuttings, strong, viable plants are obtained, which, after aging in a greenhouse or at home, are planted in open ground.
- Layers. Adult bushes have many young shoots, which are buried in the ground in the spring and left there until autumn. At the end of the autumn period, the layers are dug up and cut off from the mother bush along with the formed root system. As a result, they get independent shrubs that can survive wintering in the open field.
Prevention of various problems
To prevent the plant from dying, preventive treatments with special preparations are carried out every spring and autumn. If the procedures are not carried out in a timely manner, then fungal and putrefactive diseases can destroy a beautiful, flowering bush.
