However, experienced growers still insist on spring planting, which continues, depending on the region, from April to May 10-15.

Varieties planted before that period, the May holidays are already covered by a dense color - against the backdrop of barely hatched foliage and fresh grassy green they look very impressive.

Rhododendron Mezitt

One of the early flowering rhododendron variety is P.J. Mezitt - a magnificent plant with pink-lilac buds. The beginning of his flowering accounted for the last ten days of April - early May

It is important to choose a landing site, as in bright sunlight the plant will be uncomfortable, but in a completely dark place does not give a lush flowering.

Flowerbed with rhododendrons best to breakthe north side of the building, on the site poluzatenennom to noon, when the sun's rays reach the maximum power, the plant was completely concealed from them.

Rhododendron in the shade

Shadow barrier for the flower garden can not serveOnly the walls of the building, but the fence or tall trees. Rhododendron is quite compatible with the trees, whose roots go deep into the soil and does not hinder the development of plants - the oaks, larches, firs and fruit - pears or apple

Flowers absolutely not tolerate alkaline orneutral ground - it must necessarily be acidic, humus-rich, well-aerated, without lime impurities. One of the best materials for the cultivation of a mixture of peat and clay.

Rhododendron planted in the following order:

  • dig wells, shallow (35-40 cm) and wide enough (55-60 cm);
  • the lower part is drained sandy-pebble layer (10-15 cm);
  • poured a mixture thereof loam and peat (or upland sphagnum, low acidity), the peat should be approximately 2 times greater;
  • slightly tamped the soil inside the pit and make it the size of the hole under the earth com seedlings;
  • seedling roots dipped into the hole and covered with soil mix to the very root collar, which as a result must be flush with the ground surface;
  • abundantly watered the plant if the soil is dry;
  • produce mulching (to a depth of 5-7 cm), which are suitable for peat moss, rotted pine needles, leaves and shredded oak bark.

Mode and features watering

Drinking rhododendron moisture very interesting. On the one hand, it does not transfer completely waterlogged, on the other - requires constant irrigation and spray the specially prepared water.

Even during the site selection for the landing check,Does not fit close to the surface of the ground water. The fact that when a large amount of moisture in the soil root simply "choke" and the plant will die. It is therefore necessary drainage layer to drain excess water.

Pruning is carried out in early spring, has not yet begunsap flow. Choose strong, thick branches with a diameter of 3-4 cm, carefully cut off the ends of the clippers and cuts treated specially prepared garden pitch or resin. About a month will start the update process, which lasts for a year - and hatch new shoots begin to grow dormant buds.

Then placed in soil and covered with peat asin the case of seeds. Depending on the type of cuttings take root in 2-4 months, after which they were transplanted into boxes of peat-pine ground and take out in a cool greenhouse. The optimum temperature - 10 ° C?. Planted in the spring, along with other colors, just in boxes, and only a couple of years they can be transplanted to the main locus.

The most convenient way of reproduction - cuttings pinning. Take a flexible lower escape, beside him dig the groove depth of 12-15 cm, and the process is laid into this groove.

Reproduction processes

That he did not get up, the middle part of the stem prishpilivayut and sprinkle on top of peat. The upper part is necessary to bring out and bind to the support - wooden peg stuck into the ground

For layering care as well as for allbush - watered, sprayed. When he is rooted (in the late autumn or spring), it is separated carefully, dig and transplant for permanent growth. This method is especially good for the propagation of deciduous rhododendrons.
