An essential step in the life of a perennial, dividing perennials restores vigor to the plant and multiplies it at the same time.
It is the most economical solution to decorate 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 reserved for him at the start is becoming too small. The division will restore air to the plant and improve flowering.
