As the fall winds down, you probably have a lot spent perennial flowers that are just begging to be cleared from the flower beds. You might want to hold off till next spring to remove those dried plants.
The spent flower heads are often loaded with seeds that many birds will seek out as winter rolls in. Leaving them provides a natural habitat for the birds.
This includes your ornamental grasses that will soon turn brown. Besides providing some visual interest through the winter, the dense grass clusters and seed heads provide protection for the birds and food as well. Black-eyed susans and purple cone flowers are particularly enjoyed by finches and other colorful songbirds.
If you don’t have a crop of perennial flowers, you might want to think about adding some next year. In the meantime, perhaps a squirrel proof bird feeder could be set out. Just make sure you keep it well stocked throughout the winter months.
