Renovating Perennial Beds

Most perennial beds need at least a little renovation--even if only to move a few plants to better locations. While the plants are temporarily out of the ground, make sure to keep the root ball moist. Here, shade and a plastic tray help to conserve moisture and thus reduce shock to the plant.

There could be lots of reasons why you might want to renovate a perennial bed. Perhaps you want to change your color theme. Or maybe some aggressive weeds (or perennials) have taken over. Maybe you've moved to a new home and aren't happy with the existing garden. Here's how to make some changes:

Before Getting Started:

• Re-evaluate the site. Have trees matured or buildings been added to change the amount of sun on the garden? Has the soil been tested recently? Is there plenty of organic matter?
• Define objectives for the garden. Will more or less time be devoted to maintenance? Is a longer bloom period more desirable in the summer rather than the spring? What new plants would add interest to the garden? Will the garden's colors be coordinated with the home's interior decor? Does the renovation need to be done in phases?
• Evaluate the existing plants. Which plants will "make the cut" and return to the new garden? Are they in your color theme and have the texture and form you're looking for? Are certain plants overrun with weeds that would be introduced into the new bed? Would replacing some plants with newer varieties create a more attractive garden?

Ready, Set, Go!

1. Record the names of all existing plants, along with measurements of height and width. Take a photograph for a visual memory of colors and shapes and for comparisons of the "before" and "after" appearances as well.
2. Redesign the garden, incorporating the "spared" plants from the old garden with new additions.
3. Remove plants as necessary. If you're planning to move them or give them to friends, place the plants in flats, pots or on tarps while working. If it's early autumn, cut plants back by one-third to one-half. Divide certain plants as needed. Hold in a shady area and keep moist to reduce shock. (Plants can be kept in "holding beds" for the winter if replanting will not take place until the following spring).
4. Spray particularly weed-troubled spots with a nonselective herbicide. Be sure all weeds are under control before amending the soil; this may require several sprayings.
5. Amend soil with at least four inches of organic matter.
6. Plant the garden with "saved" and new plants.
7. Enjoy!
