Keep Perennials Healthy by Dividing
May brings May flowers and everything else green and growing.
However, no matter how warm gets now, early May is still too soon to plant most annual flowers such as impatiens, begonias, coleus, marigolds and so on. Most perennials, on the other hand, can be planted immediately. And it may be a good time to divide your perennials too.
Early spring is an ideal time to divide summer- and fall-flowering perennials. Try to tackle the task before plants reach 6 inches tall. Don’t forget to water newly transplanted divisions.
Not sure if you need to divide? Ask yourself these questions:
1) Are clumps too big and crowding other plants?
2) Has flowering been reduced during the last growing season(s)?
3) Does new growth ring a dead spot in the middle?
4) Do you want more starts of that perennial?
