cut back perennials- Tip of the Day
7th February 2020
Mild weather in many parts of the country means that new growth is starting early; it may be slightly risky to cut down perennials like penstemons now, in case there are hard frosts later on, but if you leave about 15cm of the old topgrowth it may help to protect them and it will prevent too much new growth at the top of stems from growing away.
