An indispensable stage in the life of a perennial, the division of perennials restores the plant’s vigour and multiplies it at the same time.
It is the most economical solution to enhance your garden with new plantings.
Why divide the plants?
A perennial that has been in the same place for years tends to grow strongly and take up a lot of space.
The space that was originally reserved for him is becoming too small. Division will give the plant air and improve flowering.
An old clump becomes important and the richness of the soil is often insufficient to provide the needs that are then needed.
The division will give your plant a new youth and gives you the opportunity to plant it in different places in your garden.
The best time to split the clump
It depends on the plants and varieties involved.
Generally speaking, it is carried out after flowering. Summer flowering perennials should be divided in the fall. Fall flowering perennials will be divided in the spring, usually in April. The perennial condiment plants will also be divided in the spring.
Frequency of division of perennials
There are no rules. It depends above all on the development of the plant and what you want to do with it.
However, it may be appropriate to provide for a division every 2 to 3 years.
For perennial plants aromatics and condiments …plan to divide it up every year.
Technique for dividing perennials
Point your spade in the middle of the clump you wish to divide.
For smaller, more fragile perennials, the use of a smaller tool is recommended. Slice frankly and precisely at the desired location. Leave the clump of the original plant in place. Remove by hand the clump you are going to move, separating the roots from the other part. Plug the hole thus created with a mixture of loam and soil from the garden. Plant the new clump in the chosen location in a mixture of soil and garden soil.
