Question: Can you give me some tips on dividing perennials? How do I know when they need dividing, and when is the best time to do it?

Answer: Some types of plants need division every few years, because without it flowering decreases or the center of the plant becomes too crowded and begins to die back. Division is also a easy way to propagate many perennials. Most perennials can be divided in either spring or fall; if possible, avoid transplanting during the heat of midsummer. Before you begin digging up your perennials, prepare the new planting areas, adding organic matter and any other necessary amendments. So exposed roots donOt dry out, divide plants on a cloudy (or even misty) day, make sure the soil is moist, and proceed as quickly as possible. The easiest method is to dig up the entire plant and then either cut the root mass into sections, or use two garden forks back to back to pry apart the roots. In general, each division should contain a section of the crown with 3 or 4 buds and the attached roots. Be sure to keep the newly planted divisions well watered during their first season. A thick layer of mulch will conserve soil moisture and keep the soil cool. While most perennials take well to dividing, some such as bleeding heart and monkshood are best left alone. ItOs a good idea to research individual plantsO needs before digging in.
