A little preparation this spring will give you a better garden this fall. Take stock of your fall-blooming perennials like Chrysanthemums, asters, and ornamental grasses. If they are looking a little overgrown, yet producing few flowers, it may be time to divide them. Dig them up, cut the roots into two halves, and replant the pieces, leaving space in between the two sections. Water the plants regularly to help them become firmly established well before autumn. Do the same for spring-blooming perennials this fall for a stronger spring garden.
