Growing up rhododendron

For reproduction of rhododendron, seed reproduction and vegetative reproduction are used.

To grow a plant from seed, the following is necessary. In early March, seeds are sown in picking boxes. Usually the seeds are mixed with sand, as they are very small. Contain crops at a temperature of 20 ° C. They are covered with film or glass and aired every day for several minutes (remove the film or glass) so that mold does not appear. Water is poured over with rain or thawed snow at room temperature, carefully, as necessary. At the stage of unfolded cotyledons, seedlings dive at a distance of three centimeters. After three weeks, the seedlings are fed with physiologically acidic mineral fertilizers (potassium sulphate or ammonium, superphosphate).

You can take out all summer boxes on the balcony. Seedlings are fed twice a month until the second picking. The second pick is done in August. Plants are placed at a distance of four centimeters. The composition of the soil should be sour, bezvesvestkovym. For the winter, the boxes are transferred to the premises, kept at a temperature of 8 ° C. By spring, it is gradually increased to 20 ° C. In late May, seedlings are planted in the open ground.

For cultivation of rhododendron in the open field use the following soil mixtures: heather, leaf earth and coarse sand (3: 1: 1) or peat moss peat, turf ground and coarse sand (4: 1: 1). The mixture must be sifted through a large sieve. If you sift through the shallow, then such a land when watering will not pass air.

Rhododendron is propagated by vegetative means. There are four such methods: cutting, dividing the bushes, grafting and reproduction by layering. To learn how to propagate rhododendron in any of these ways, read the article "Plum".
