Divide perennials in March
Some perennials get congested and are best divided up every few years, or maybe yoiu just want some extra plants.
Just as you see the first signs of new growth. You can use two forks to prize apart stubborn clumps. With some perenials you can get almost unlimited plants. Ensure that each piece of stem has enough root. Large bits can go straight back in the ground. Small pieces are best potted.
You can divide congested clumps of snowdrops ‘in the green’ as the flowers go over.
