It is the best of all to replace perennial plants or in the spring when the soil has already got warm, but still quite damp, or at the very end of summer. If the plant has the deep and compactly located roots, it is necessary to dig out it carefully not to damage root system.
Experienced gardeners at first cut the earth around perennial to take out it together with root lump. It is the best of all to dig out plant together, standing opposite to each other.
The taken-out perennial should be replaced to the new place as soon as possible, then he will better take root. For this purpose holes on the chosen place for change should be dug in advance. Surely remove from root lump weeds and also all the old, sick or damaged sites of rhizome. Then separate perennial into quantity of parts (allotments) necessary to you. It is the best of all if you separate bush sharp shovel in two in its central part which the oldest, and then you will already choose planting stock from extreme young parts.
Do not forget that the size of the dug-out holes has to be sufficient in order that there roots of allotments freely were located. If it turns out that holes are small, expand and deepen them. Then fill a little prime quality land mixed with humus in the center and place allotment on this hillock, having tried to distribute roots evenly. Fill up from above with thin layer the earth, slightly stamp to record plant, and well water. When water is absorbed, dosypta the earth to edge of hole. In order that the plant has better taken root, recommended to zamulchirovat hole. It will keep moisture in the soil and will reduce the probability of emergence of weeds. It is very important to choose correctly the place for landing of perennials. It concerns not only conditions of the soil and the neighbourhood with other plants, but also illumination level. There are photophilous perennials which badly transfer even partial shadowing, and is shade-loving which need to be put from North side of lodge, the shed or gazebo. Therefore take away for photophilous plants open areas on South side of your garden so that on them the shadow from tall neighbour's trees or constructions did not fall. And then they will well take root, pleasing your look with beautiful blossoming.
