Planting and caring for Daurian rhododendron

Daurian rhododendron is unpretentious in cultivation and care. Subject to agrotechnical rules, the shrub will delight you with abundant, lush flowering, which occurs in the last days of April.

Selection and preparation of the landing site

Before planting a young rhododendron, it is necessary to prepare the site 3 weeks in advance. Site preparation for landing:

  1. A landing hole 50x70 cm in size is dug at the selected place.
  2. The bottom is covered with expanded clay, broken brick by 10-15 cm.
  3. For mass plantings of Darsky rhododendron, the planting rate should be 2 plants per 1 sq. m.
  4. Next, the pit is 1/3 filled with nutrient soil. If the soil is clay, then use a purchased substrate for azalea or independently prepared from peat, leaf turf and needles, mixed in a ratio of 2: 3: 1. 70 g of complex mineral fertilizers are added to the finished soil.
  5. The well is covered with dark plastic and left for 2 weeks.
  6. After the earth warms up well, the film is removed, and the hole is spilled until the earth absorbs moisture.

Seedling preparation

It is better to purchase dahurian rhododendron seedlings in a nursery, at the age of 2-4 years. Before buying, you must carefully inspect the seedling. You need to choose strong, viable young plants that have whole roots without signs of rot and healthy, brightly colored shoots. The seedling should not show signs of rot and mechanical damage.

If the seedling is purchased with a closed root system, it is spilled abundantly before planting. And specimens with open roots are kept for 12 hours in water at room temperature with the addition of a root formation stimulator.

Planting rules for Daurian rhododendron

A seedling with a straightened root system is placed in the prepared hole. The plant is carefully sprinkled with nutritious soil, tamping each layer so as not to leave an air space. The planted plant is spilled abundantly, the trunk circle is mulched. Coniferous sawdust, straw, foliage are suitable as mulch. It will stop the growth of weeds, oxidize the soil, retain moisture and become an additional organic top dressing.

Important! In a properly planted seedling, the root collar should barely protrude above the soil surface.

Daurian rhododendron is unpretentious in care. To obtain a lush and abundant flowering, you must follow simple rules:

  • watering;
  • top dressing;
  • weeding;
  • pruning;
  • preparation for winter;
  • prevention of diseases.

Important! Due to its cold resistance, Daurian rhododendron can be grown in the North-West region and in the Moscow region.

Watering and feeding

Watering the rhododendron is done as the top layer of the earth dries out. In hot dry summers, irrigation is carried out 2-3 times a week with warm, settled water. Hard water negatively affects the root system, so experienced growers recommend softening it with citric acid or vinegar (100 g per bucket of water). In order for the plant to be saturated with moisture, up to 20 liters of water are consumed under each bush.

Important! To maintain the acidity of the soil, sulfuric acid must be added to the water.

After watering, do a superficial, neat loosening and weed removal. Weed grass takes up nutrients and is a carrier of diseases and pests.

For abundant and lush flowering, root feeding is necessary:

  1. For the first time, 10 kg of rotted manure or compost is introduced at the beginning of the growing season. Organic matter is necessary to build up the green mass, for the formation of buds and the formation of flower buds of the next year.
  2. The second feeding is carried out immediately after flowering. To do this, use phosphorus-potassium fertilizers, diluted strictly according to the instructions.

Important! When using complex mineral fertilizers, it is necessary to give preference to those that contain a minimum amount of chlorine, lime and phosphoric acid.


Daurian rhododendron does not need to form a crown, since the plant has a genetic basis for the development of the correct decorative form. Pruning is carried out sanitary and anti-aging. Shoots from old bushes are shortened, leaving a length of 30-40 cm from the soil surface.

After flowering, all faded brushes are promptly removed. Since they spoil the decorative effect and interfere with abundant growth and future flowering. Pruning must be done keeping the axillary bud on the top sheet. In order to avoid the attachment of diseases, pruning is carried out with a sharp, sterile tool, and the cut points are treated with brilliant green or covered with garden pitch.

Preparing for winter

Daurian rhododendron is a frost-resistant culture that can easily withstand frosts down to -40 ° C. An adult plant does not need shelter, except for abundant watering, mulching of the trunk circle and feeding with phosphorus-potassium fertilizers. In order not to lose a flowering variety, it is only necessary to cover a young seedling for 2-3 years, until the bush gets stronger and grows a powerful root system. For this:

  • the seedling is spud with peat or rotted compost, while closing the root collar;
  • spill abundantly with warm, settled water;
  • fed with wood ash;
  • the crown is tied with agrofibre or roofing material;
  • the shelter is removed in the spring, only after the soil has warmed up.

Is it possible to keep the Daurian rhododendron at home

Dahurian rhododendron is not recommended to grow at home. Since the plant is poisonous and exudes a strong, sweet aroma during flowering. Regularly inhaling the smell of flowers, the nervous system loosens, regular headaches and dizziness occur.

Advice! As a home plant, flower growers recommend purchasing a flowering azalea, which is considered a relative of the rhododendron.

Reproduction of Daurian rhododendron

When you purchase one plant, seeing its beautiful flowering, you always want to propagate it in order to turn the garden plot into a spring, blooming carpet. It is not difficult to root a Daurian rhododendron, even a novice florist can cope with this. There are 3 ways of propagation: by seeds, cuttings and branches.

  1. Seed reproduction is a laborious and long-term occupation. Therefore, it is not suitable for beginner florists.
  2. Offsets are an affordable and effective breeding method. In spring or autumn, the strongest, healthiest shoot located closer to the ground is chosen on the bush. The lower leaves are removed, the upper ones are shortened by ½ the length. The prepared shoot is laid in a trench, leaving the top above the surface of the earth, to a depth of 4-6 cm. To speed up the process of emergence of roots, the earth must be moistened and mulched. For 2 years, the young plant can be separated from the mother bush and planted in a permanent place.
  3. Cuttings - in June, after flowering, cuttings 10-15 cm long are cut. The lower leaves are removed from the planting material, and the cut is made at an acute angle. The stalk of rhododendron is set at an angle of 30 ° into the nutrient soil and removed to a warm room, regularly making sure that the soil is always moist. After 1.5 months, the cutting is transplanted into a large container and transferred to a cool but bright room. 2 years after the seedling gets stronger and grows the root system, it can be transplanted to a prepared place.

Diseases and pests

Daurian rhododendron has strong immunity to diseases. But if the agrotechnical rules are not followed, the bush often affects the following diseases:

  1. Chlorosis - the disease appears with stagnant water, lack of nitrogen and potassium. The first signs of a fungal disease are the appearance of yellow spots on the leaf plate. Treatment consists in spraying the shrub with ferrous sulfate solution.
  2. Necrosis - the disease often appears on young plants, with sudden changes in temperature and humidity.
  3. Root rot - the shoots become soft, the leaves acquire a dull ash tint, dry out and fall off. The disease often appears when growing a bush on clay, poorly drained soil. In order not to lose the plant, it is transplanted into a light, nutritious soil.

  2. The foliage turns yellow and falls off, these signs indicate nitrogen starvation.When growing a shrub on sandy soil, the foliage becomes smaller and brighter, the growth of the plant slows down, flower buds are not laid. At the end of summer, the leaf plate acquires a lemon color, dries up and falls off. To prevent the appearance of this problem in the spring, the bush is fed with nitrogenous fertilizers.

In order not to face serious problems and not to lose the Daurian rhododendron, it is necessary to eliminate some factors:

  • increase acidity;
  • carry out regular watering and feeding;
  • plant the plant on light, drained soil, in a well-lit place;
