May and along with it the frosts.
Frosts are good though as without them flowering will be nowhere near as good.
It is too late to order plants for this season from us now sorry. We are all tidied away for the winter.
Things To Do:
- You should have cleaned off dead leaves by now.
- Aerate the soil around the crowns and apply a light mulch around but not over the crown.
- If you have not fertilized for several years then a handfull of Potasic Fertilizer will be beneficial.
