For effective fall clean-up gardening in southeastern Pennsylvania, consider the following tips gathered from various reliable sources:
General Fall Preparation: According to the Hoffman Design Group, autumn is an ideal time for landscaping enhancements, such as planting trees and shrubs. The period from September to November offers the best opportunities for these additions. Thus, use this time not only to clean up but also to plan for future growth in your garden.
Remove Annuals and Debris: The Penn State Extension emphasizes the importance of clearing out annuals and any plant debris from your garden following the first frost. This cleanup not only tidies up the garden but also helps prevent any diseases from lingering over the winter. You can compost healthy plant material while disposing of any diseased items properly.

Leave Some Leaves: The Lehigh County Authority suggests a more relaxed approach this fall. Experts recommend leaving fallen leaves on your lawn as they can provide insulation for the grass and habitat for beneficial wildlife. Rather than exhaustive pruning and cleanup now, it’s better to wait and conduct a more thorough spring clean-up.
Maintenance Scheduling: The Rutgers Nursery outlines a year-round maintenance schedule that includes cleaning up perennial beds after the frost, which involves cutting back any dead growth. Additionally, this is a good time to plant hardy spring-flowering bulbs to prepare for the next growing season.
Vegetable Planting: For those interested in fall vegetable gardening, timely planting is crucial for a successful harvest. As outlined by PhillyBurbs, ensure you plant crops early enough in the fall to allow them to mature before cold weather sets in.
By following these guidelines, residents in southeastern Pennsylvania can ensure a healthy transition into winter while laying the groundwork for an active spring gardening season.
