The division consists in cutting or tearing the dug up plant into several or a dozen parts.Most perennials reproduce this way every 4-6 years, while plants with a short life, such as . firletka, great pyrethrum, large-flowered recess, every 2-3 years.
The division date depends mainly on the flowering time.The general rule is that perennials that bloom in late summer and autumn should be divided into spring before they start growing or just after they start growing, whereas, flowering in spring and summer, we divide the autumn, or more precisely from mid-August to September, so that they can take root well before winter. It is not difficult to notice that we separate plants outside the period of flower bud formation and flowering.In full vegetation, we divide sedum, colony and saxifrage.
We can also start dividing perennials very late in autumn (in November).However, provided that we have rooms for the winter for divided plants and that the temperature in them does not drop below 0 ° C.First, dig up the selected he althy perennials, preferably with a pitchfork, and then separate them.
If they are species with compact carp, such as paniculate or funkies, do it with a sharp shovel, knife or a small hand saw (effective for thick and hard roots or rhizomes), while the plants have loosely connected roots, e.g. carpets, we will divide them with our hands.Large wounds formed during such an operation should be slightly dried and covered with charcoal dust.Dividing one 3-6-year-old plant will yield 5-10 new ones on average.
There must be at least one bud and he althy roots on each separated section. Too long roots can be shortened to 10-20 cm (depending on their size).Shorten the above-ground parts (leafy shoots) by 1/3 to even 2/3 of the length just before or immediately after digging out the perennial to maintain the balance between the damaged root system and the organs transposing water, i.e. leaves and stems.However, we do not trim the shoots when dividing in the spring, because then the plants start to grow.
