As the warm summer days give way to cooler temperatures, it's time to start thinking about transitioning your garden and landscape for the fall season. September is the perfect time for St. Louis homeowners to prepare their outdoor spaces for the changing weather while ensuring a smooth transition that keeps your landscape healthy and vibrant. Here are some essential tips to help you get your landscape fall-ready.
1. Pruning and Deadheading
Pruning is one of the most important tasks as you transition your landscape from summer to fall. By trimming away dead or damaged branches, you allow your plants to focus their energy on developing strong roots and staying healthy through the colder months. Here’s how to approach pruning:
- Deadheading: Remove spent flowers from perennials like roses and daisies to encourage more blooms or redirect the plant’s energy into root growth.
- Trim shrubs and trees: Cut back any overgrown or damaged branches to prevent breakage during winter storms and improve airflow, which reduces the risk of disease.
2. Fall Mulching
Mulching in September provides several benefits for your landscape. It helps regulate soil temperature, conserves moisture, and adds nutrients to the soil as it breaks down over time. As the weather cools, mulching can insulate the soil, keeping roots protected during temperature fluctuations.
- Apply a 2-3 inch layer of mulch around trees, shrubs, and flower beds, but be careful not to pile it against the plant's base, which can cause rot.
- Consider using organic mulches like bark, compost, or shredded leaves, which will also enrich the soil as they decompose.
3. Plant Fall Foliage and Late Bloomers
September is a great time to plant fall-blooming flowers and foliage that will add color and texture to your garden as the seasons change. Here are a few popular options for St. Louis landscapes:
- Chrysanthemums (Mums): Known for their rich autumn colors, mums are perfect for adding vibrant reds, oranges, and yellows to your garden.
- Ornamental Kale and Cabbage: These hardy plants offer stunning purple, green, and white foliage that lasts well into the cooler months.
- Asters: These daisy-like flowers bloom in late summer and early fall, providing long-lasting color to your landscape.
Planting these fall bloomers now will ensure they establish roots before the ground freezes, giving them a strong start for next year’s growing season.
4. Lawn Care: Aeration and Overseeding
September is the perfect time to give your lawn some extra attention. After the hot summer months, your grass may be looking tired, but aeration and overseeding can help rejuvenate it:
- Aeration: Core aeration loosens compacted soil, allowing water, air, and nutrients to penetrate the root zone. This helps your grass grow stronger and more resilient.
- Overseeding: After aerating, overseed your lawn with cool-season grasses like fescue or ryegrass. These grasses thrive in cooler temperatures and will help fill in thin or patchy areas.
5. Clean Up Garden Beds
As part of the transition from summer to fall, it’s important to clean up your garden beds to prevent diseases and pests from overwintering in your landscape. Remove any dead or diseased plant material, weeds, and fallen leaves to keep your garden tidy and healthy.
- Consider composting the healthy plant material to recycle nutrients back into your garden, but discard any diseased plants to prevent contamination.
6. Prepare Perennials for Winter
Now is the time to give your perennials the care they need to survive the winter months. After trimming back dead foliage, consider adding a layer of mulch around the base of the plants to insulate them during cold weather.
- Divide perennials like hostas and daylilies in September to prevent overcrowding and promote healthier growth next spring.
