Perennial plants division

The division of perennials

Perennial plants are said to be herbaceous plants which, year after year, develop new shrubs and new flowers, but which winter without visible aerial part; these plants tend to turn yellow and dry with the onset of cold; from the bread of roots, however, in spring we will see new shoots, which will quickly bring us a new plant. They are very common plants in gardens, also because they allow us to have a series of plants already ready in the garden every year, without having to wait for the development of the annuals, when the climate is still cold. Most perennials in fact do not fear the cold, and the roots bread is left directly at home, expanding from year to year.

Many perennials are self-seeding from seed, this means that the flowers of the dwelling plants produce seeds that, once fallen into the ground, germinate there, giving rise to new plants the following year; this type of propagation is not always the best, especially in the case of hybrids or particular varieties: in fact the seeds of a hybrid do not always produce plants identical to the mother plant, very often instead they give rise to plants of inferior quality, with smaller flowers or less colorful.
The best method to obtain plants identical to the one we have planted is to divide the bread of roots; this operation is carried out at the end of summer-beginning of autumn, or when the plant has begun its vegetative rest and the aerated part is totally, or partially, dried.
In this period of the year, in fact, the plant will suffer less than the operations necessary to divide it.
We proceed by eradicating the entire bread of roots that is found at the base of the plant, trying not to ruin the outer and subtle roots; once this is done, the bread is divided into several portions, keeping a good amount of well-developed roots for each part. At this point the small portions are buried up to the depth to which the entire plant was before, leaving a good amount of space between one portion and another. If necessary we proceed to water, but with the approaching winter it will not be necessary to water again.

This method of propagation, as we said before, offers the primary advantage of guaranteeing us to obtain other plants identical to the mother plant, with the same foliage, equal vegetative growth and equal flowering.
Moreover it seems that many species of perennial plants have a real rejuvenation from the division: with the passing of the years in fact some species of perennials tend to develop less and less and to bloom in scarce way; the division allows us to rejuvenate even these plants, which will therefore be more luxuriant and floriferous in the following spring.
This type of operation is also carried out to produce new plants to be placed in pots or in other parts of the garden, not only to expand the already existing flowerbed.
