6. Leave seed heads standing. Perennials include Echinacea, Sedum, Ornamental Grasses, and Clematis standing to provide habitat for pollinators and food for birds over the winter months. These also provide texture and visual interest to the winter garden.
7. Clean up plants as they fade. Cut back any perennial that is diseased and dispose of the trimmings in the trash, rather than your compost pile, to prevent the spread of the disease. Cut back yellowed foliage on perennials such as Daylilies, Iris, Peonies, Bee Balm, and more.
8. Divide and conquer perennials that spread. Dig up and divide Daylilies, Iris, Hostas, and more in September if they have become overcrowded or outgrown the space. Learn More: How To Divide Plants This Fall
9. Mulch. Adding a layer of mulch in your garden beds to provide a nice layer of protection to prevent soil erosion, add some organic matter to the soil, and protect plants from snow and ice over the winter months.
10. Plant cover crops. Build your garden soil for next year by adding quick-growing cover crops. Plant Clover, Vetch, and Austrian Winter Pea as “green manures” to help build nutrients and get the soil ready for next spring’s planting.
The more you accomplish in September, the less work you’ll have to do in spring!
- If you’re thinking of adding a pollinator garden to your landscape, try to prep the area and get as much planted as you can this fall. Come spring, the plants will be much larger and that area will be primed and ready to add in annuals and other varieties.
- The more weeding and mulching you do in September, the less weeds you’ll have to deal with in the spring. Take advantage of the gorgeous weather that September brings and get yourself in a great position to start next season off running.
