Fall will be arriving soon. It’s time to prepare the garden for a rest. I start by walking around the flower beds and see what needs to be divided and transplanted. I like to divide many of my perennials in fall, for several reasons. First, the plants will come up next spring looking whole. Second, I can see how big things have gotten and where I have holes to fill. Third, cooler temperatures make it easier for the plant to recuperate from being separated. And fourth, recent transplants need extra water, which fall rains can provide.
