Be rewarded with double the number of blooms next summer! - by Graham Ross
  • 03 Nov 2020

Double your agapanthus without having to pay extra for them. Imagine what you'll be looking at in a few months!

Every two or three years you need to dig up your agapanthus and divide them. You can tell they need dividing if they are flowering less over the summer as they maybe too cramped and need more space to shine. Do this in autumn or early winter.
