The best soil is a riding sour peat or a mixture of sand with sand . The general requirement is an acidic soil reaction, which indicates the growing of such plants like a mint of a dog, sowless small, Veronica.
Then it is necessary to prepare a landing hole for the bush. It usually makes a 60-70 cm wide, a depth of 30-40 cm. On clay soils - less deep by 20-25 cm, but wider (1.0-1.2 m). Fill the pit peat (horse) or a special soil mixture purchased in the store.
It is best to acquire a three-year rhododendron seedlings with a closed root system. Spring plant plant (mid-April - the first decade of May) or autumn (September). We put a com from the ground into the water so that it would be good in moisture, and then lower it into the prepared pit.
We plant so that the top of the coma with the roots was at the level of the pit, not blocking the root neck. I fall asleep the pit and water the bush. After a couple of days, the soil should be closed with sawdust (layer 5-7 cm).
If you want to plant a few plants nearby, then the distance between them should be at least 1 m. But still it is worth focusing on the size of the bush itself. For example, per quarter. m can be placed one r. Yellow or 4 R. Canadian.
