Varieties, planted early, in early may, already covered with flowers on the background barely emerged leaves and grasses.
A place to land
In the sun rhododendron will feel uncomfortable, and in a shaded place will not give abundant flowering. Flower bed with shrubs it is better to break on the North side so, at noon the plant was closed from the scorching sun. Barrier from the heat can serve not only the wall of the building, but the tall trees, fence. The rhododendron gets on well with trees with a deep root system: larch, oaks, firs, Apple, pears.
Requirements to the soil
Bush does not tolerate a neutral or alkaline soil, the soil must be acidic, rich in humus, free of impurities lime, well-aerated. The best part – a mixture of clay and peat.
The procedure for planting
- Dig a shallow pit to 40 cm, width – 60 cm;
- drainage – sand-and-shingle, layer 10 – 15 cm;
- to fall asleep a pebble with a mixture of top or sphagnum, with a slight acidity, peat and loam, peat should be twice the;
- the soil is compacted, to make a hole beneath a seedling;
- seedling to fill the soil to the root collar, it should be on the same level with the soil;
- the plant is watered;
- do mulching with peat, moss, rotted pine needles, shredded bark and oak leaves to a depth of 5 – 7 cm.
Before planting, the roots can be wet, dropping in a container of water. Keep until then, until no bubbles appear. Another piece of advice from experienced gardeners, how to achieve better development of the root system. If flowering plants to cut the lush buds of the seedling more effort spent on early rooting.
Many varieties of rhododendrons are not afraid of frosts up to – 30 degrees. But still better to be safe and to cover up the plant with spruce branches, lutrasilom or matting. Before the onset of winter the bushes well watered. A bright spring sun can burn the foliage, it is necessary to make a shade.
Landscape design and care tips
The roots of the rhododendron are close to the surface, loosen the soil to be very careful, the digging is eliminated. Weeds also better to remove manually, a garden hoe or knife can harm.
To moisture the shrub is twofold: he does not tolerate waterlogging, but it requires spraying and watering specially prepared water. For 12 – 20 hours before watering in the tank is placed sphagnum peat to acidify. The best option is rainwater, you can use water and, but her need to defend. The need for watering "tells" the plant itself: as soon as the foliage loses its glossy Shine – it's time to water procedures. On the site, where planted rhododendron, should not be groundwater, close matching to the surface, otherwise, the roots can die.
Look spectacular rhododendrons, if they are groups. Planting shrubs can be placed near the tracks, paths, on the edges of lawns, close to pools and fountains, where in summer the humidity is increased. The tallest plants are planted in the center of the group, low – on the edges. The rhododendrons look good and grow near conifers, such as spruce, pine, thuja. Soliternyh landing on nice green lawns, from the bushes to create a hedge.
Bush does not need the formation of the crown, but sometimes it is necessary to thin out, remove old stems. Pruning is done in early spring, prior to the beginning sokodvizhenija. Strong and thick branches with a diameter in 3 – 4 cm are cut gardening shears, wounds are treated with resin or garden pitch. A month should start the process of rejuvenation: begin to grow the buds, hatch new shoots.
Rhododendrons bloom unevenly: this summer, they can please a lush color, and next year the results can be very modest. To minimize these processes, withered buds must be removed.
The plant must maintain from the beginning of planting and during the flowering period. To preserve the acidity of the soil applied potassium sulfate, superphosphate, nitrate potassium, ammonium minimum concentration, calcium sulfate or magnesium. Early spring make nitrogen fertilizers, a second feeding in July. The ideal way is fertilizing liquid solution of natural fertilizers: cow manure, Horny flour. Rotted manure is diluted with water at a ratio of one to fifteen, insist four days.
In a year or two after planting, the top soil update. Humus or compost in equal proportions mixed with peat and sprinkled with a mixture of areas around the roots. In the filling you can add superphosphate, ammonium or potassium sulfate.
The types of reproduction

For propagation by cuttings take half lignified shoots, cut them into cuttings 7 – 8 cm long. From the bottom remove leaves, the end is placed in a container with a growth stimulant, planting material is kept in the solution for 12 – 15 hours. It was then placed in peat soil, the cuttings should root within 2 – 4 months. The following procedure transplantation in boxes with peat coniferous soil, it is better to put in a cool greenhouse. In spring the rooted cuttings are planted together with other plants directly into boxes, two years later, they can be transplanted to a permanent place.
The fastest and most convenient way of propagation of rhododendron – pinning cuttings. Flexible bottom escape is placed in the excavated groove 12 – 15 cm deep. Strains poured, sprayed, rooted plants are separated from the parent Bush, dug and transplanted to a permanent place. This method is the most good for the deciduous species of rhododendron.
