A new lawn can also be established by sodding. Fall sodding can be done until the ground freezes or is covered with snow. Trees and Shrubs Balled and burlapped and container-grown trees and shrubs can also be planted in late summer and fall. Evergreens should be planted from mid-August through September. Planting during this period allows the evergreens to become established before the onset of winter.
Evergreens planted in late fall are susceptible to desiccation injury and death.
While most trees and shrubs do well when planted in late summer and fall, some woody plants root slowly and should only be planted in the spring. Trees and shrubs planted in late summer and fall should be watered every 7 to 10 days during dry weather. Continue watering until the ground freezes. Perennials Late summer and early fall is an excellent time to plant many perennials. It is also a good time to move or divide perennials, such as peony, daylily, garden phlox, and oriental poppy.
