Order spring bulbs—the sooner the better for the best selection and rarities. Plant more snowdrops (Galanthus nivalis, Zones 3–8) than you think you need! They look best in large clumps.

Overseed, mulch, and/or fertilize your lawn.

Remove dead and/or faded annuals, unless you want to collect seed or let them self-seed.

Prune dead branches from trees and shrubs.

Select and plant new trees and shrubs. The warm soils of September will encourage new root growth and allow newly installed trees and plants to be more successful.

Enjoy late summer and early fall grasses. Observe the many varieties to help direct your own selections.
