The light has become golden, and the crisp winds of autumn are lurking just around the corner. Enjoy the twilight of summer in the September garden!
What To See in the September Garden
- Caryopteris is in full bloom, and the asters and mums are starting to open.
- The first of the trees are beginning to change color.
- Butterflies are enjoying the late-summer flowers and basking in the sun.
- Winterberry fruits are starting to turn red. The beautyberry fruits are shading to purple.
What to Do in the September Garden
- Take advantage of cooler weather to plant container-grown trees, shrubs, and perennials.
- Plant your containers and windowboxes with favorite fall annuals.
- Harvest pears, apples, everbearing strawberries, and autumn raspberries. Keep harvesting melons, tomatoes, peppers, and other warm-season crops too. Potatoes are ready once the tops die back.
- Finish up fall vegetable planting. Plant radish, onion sets, leaf lettuce, endive, and spinach for harvest later in the fall.
- Bring in poinsettias and amaryllis if you’ve had them in the garden all summer. Both amaryllis and poinsettia require a darkened and cool storage period.
- If you haven’t yet ordered bulbs for fall planting, shop for them now. Local garden centers and on-line sources will have a great selection of spring-blooming bulbs at this time.
- Continue cutting lawn at a minimum of 3” and mow in late afternoon or early evening to conserve soil moisture. Consider using an organic lawn fertilizer in late September.
