Fall Garden Maintenance Checklist for Pennsylvania

As summer fades and fall’s crisp air settles in Pennsylvania, it's time to turn your attention to garden maintenance. Fall is a crucial period for preparing your garden for the winter months and ensuring a vibrant start come spring. Whether you’re an experienced gardener or a novice, this checklist will help you keep your garden in top shape throughout the autumn season.

1. Clean Up Debris

Start by clearing fallen leaves, twigs, and other debris from your garden beds and lawn. This helps prevent diseases and pests from overwintering in the decaying matter. Use a rake or leaf blower to gather leaves and compost them or use them as mulch.

2. Cut Back Perennials

Many perennials, like coneflowers and black-eyed Susans, benefit from being cut back in the fall. Remove spent blooms, but leave the stems of plants like ornamental grasses and certain seed heads which provide winter interest and habitat for wildlife. For plants that are prone to disease, cutting back can reduce the risk of issues in the spring.

3. Prepare Your Soil

Fall is an excellent time to enrich your soil. Add compost or well-rotted manure to your garden beds to improve soil structure and fertility. This organic matter will decompose over the winter, enhancing the soil for the growing season. Test your soil if you haven’t done so recently to determine if you need to amend it with lime or other nutrients.

4. Divide and Transplant

Fall is a great time to divide and transplant perennials that have outgrown their space or need rejuvenation. Plants like hostas, daylilies, and peonies can be divided now. Be sure to transplant them while the soil is still warm, which helps roots establish before winter.

5. Protect Tender Plants

In Pennsylvania, winters can be harsh, so it’s important to protect tender plants. Apply mulch around the base of perennials to insulate the roots. For more sensitive plants, consider using burlap or row covers to shield them from extreme temperatures and wind.

6. Prune Trees and Shrubs

Late fall, after the leaves have fallen, is a good time to prune deciduous trees and shrubs. Remove any dead, damaged, or crossing branches to improve air circulation and shape the plant. Avoid heavy pruning on spring-flowering shrubs as this may remove next year’s blooms.

7. Plant Spring-Flowering Bulbs

Don’t forget to plant spring-flowering bulbs such as tulips, daffodils, and hyacinths before the ground freezes. Plant them at a depth of about three times the height of the bulb and space them according to the variety. A well-drained spot with full to partial sun is ideal.

8. Winterize Your Garden Tools

Clean and sharpen your garden tools before storing them for the winter. Remove any dirt, sap, or rust, and oil the blades to prevent corrosion. Store tools in a dry place to avoid damage from moisture.

9. Check Your Irrigation System

Before the first frost, make sure to winterize your irrigation system. Drain hoses, remove any filters or nozzles, and store them in a sheltered location. For in-ground irrigation systems, follow the manufacturer’s instructions for winterizing.

10. Plan for Next Year

Fall is also a good time to reflect on the past gardening season and plan for next year. Take notes on what worked well and what didn’t, and start sketching out your garden plans for the spring. Consider adding new plants or changing garden layouts based on your observations.

Bonus Tips

• Wildlife Considerations: If you feed birds, make sure to keep feeders stocked as natural food sources become scarcer.
• Cold Frames: If you want to extend your growing season, consider setting up a cold frame or hoop house to protect and grow cool-season crops.

By following this fall garden maintenance checklist, you’ll set the stage for a thriving garden in Pennsylvania’s varied climate. Proper preparation now ensures that your garden will be ready to burst into life when spring arrives. Enjoy the changing seasons and the satisfaction of a well-cared-for garden!
