Tips for dividing perennials

The division of the perennials in the garden has two sides to it. Perhaps the best-known playback but also keep in mind that will help us to have healthier plants. With these simple tips we hope to show the advantages of this technique.

There are several reasons to divide the perennials when they have already developed quite:

  • For health reasons, because the perennials will stay more healthy if we divide every 3-4 years
  • To protect them from fungal diseases and pests
