Late summer is a wonderful time to cut bouquets for all your friends — the garden is so bountiful! Elephant ears, Rudbeckia daisies, Dahlias, and fountain grasses all provide such interesting texture and color!
Squashes are ripening, the lawn needs mowing again, and many summer bloomers like rudbeckia daises, nippon daisies, echinacea, gaillardia, and sneezeweed will continue blooming if the spent flowers are cut off (gardeners call this deadheading). Some, like summer phlox, sundrops, and other early summer bloomers can be cut to the ground.
Fall is also the one time each year for fertilizing cold-season grasses like kentucky blue grass. (You have cold-season grass if your lawn is green during the winter.) This helps encourage root growth in the cooler weather, in preparation for winter. If you need to reseed any patches or start a new lawn, early September is the time to put down seed and water daily until germination.
September is also the time for starting a new batch of cool-season vegetables, like lettuces and leafy greens like kale or chard. These will provide greens until and beyond the first frosts. Gardeners who use row covers or other protection can often harvest right through the winter in our mild climate.
