Annuals. Pull out faded spring and summer flowers and replace them with cool-season annuals such as calendula, ornamental cabbage & kale, pansies, primrose, sweet peas & violas. Give them a strong start by fortifying the soil with GreenAll® Soil Booster. Keep the soil moist while plants develop and, if weather is hot, temporarily shade new seedlings. We have a spectacular selection here at Evergreen and our friendly experts are happy to help you choose the best plants for your garden.
Bulbs. Spring blooming bulbs will be arriving soon. Shop early for the best selection of healthy bulbs. Chill crocus, hyacinths, and tulips in the refrigerator for about six weeks before planting, keeping them away from fruits and veggies, especially apples, which can thwart bulb development.
Fall-blooming perennials. Add fall color to your garden with asters, chrysanthemums, gaillardia, gloriosa daisy, purple coneflower, and salvia.
Perennials, Trees & Shrubs. September marks the beginning of fall planting season; the ideal time to get many plants into the ground. Trees are starting to show their fall foliage color now, so it’s a great time to shop to get the fall color you desire. Set out transplants of campanula, candytuft, catmint, coreopsis, delphinium, dianthus, foxglove, penstemon, phlox, salvia, hollyhocks and yarrow this month. They will become established over the winter and give you a lovely spring and summer garden.
Create an Autumn Show in Containers. Cluster several pots together for a lovely autumn show. Use large containers and a good potting mix, such as GreenAll® Organic Potting Soil, and buy blooming perennials in gallon cans. Mix grasses and blooming plants for a variety of color and textures.
Harvest. Continue harvesting summer vegetables such as tomatoes, beans, eggplants, squash, and cucumbers. Remove plants that are no longer producing, or plants that have succumbed to disease. Make sure not to put diseased plants into your compost pile!
Start Fall Crops. As you pull out early-summer crops, replace them with beets, broccoli, carrots, chard, collards, cabbage, cauliflower, kale, lettuce, radishes, spinach and turnips. Most will be ready to harvest in autumn. Starts and seeds of these vegetables and more are coming into the nursery now. Make sure to use E.B. Stone Organics Sure Start when putting out your new veggies.
Divide Perennials. If perennials like agapanthus, candytuft, coreopsis, daylilies, society garlic and penstemon are overgrown or not flowering well, it’s time to dig and divide them. Use a spading fork or shovel to lift clumps, then cut the clumps into sections. Replant sections in well-amended soil and keep moist while new roots develop.
Water. Keeping plants irrigated is a gardener’s most important task this month. Vulnerable container plants may need a daily soaking as we have many hot days in September. Shallow-rooted plants like avocado and citrus need to be watered more frequently as well.
Pinch and Prune. Keep your blooming flowers looking good by deadheading spent flowers and cutting back rangy annuals and perennials by at least one-third. Cut spent roses to the 2nd 5-leaved branch to get one last burst of blooms in fall.
Prepare beds. Before fall planting, amend soil with compost and soil conditioner, such as GreenAll® Soil Booster.
Control Weeds. This is the gardener’s never-ending battle. Stop weeds like oxalis and broadleaf types in your lawn with Bonide® Weed Beater Ultra. Throughout your beds, spot treat with Bonide® KleenUp.
Fertilize roses. Roses are heavy feeders and usually require both a spring and summer feeding. Now is a good time as later feedings may encourage soft growth late in the season. E.B. Stone Organics Rose & Flower Food is a good choice.
