The light has become golden, and the crisp winds of autumn are lurking just around the corner. In Indianapolis, we’re deadheading and weeding, planting fall container gardens, and watching the butterflies flit through the yard. 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. Anemone is blooming too.
- The very first of the trees are beginning to change color here in zone 6.
- 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.
- Seed heads on grasses are waving in the late-summer breezes.
What to Do This Month
Contact Spotts Garden Service to schedule work in your Indianapolis garden. Fall is an especially good time for:
- Completing hardscape projects and improving how the landscape handles water.
- Taking advantage of cooler temperatures to plant perennials, shrubs, and container grown trees, as well as digging and dividing existing perennials.
- Ordering spring-blooming bulbs to plant in October.
- Planting containers and windowboxes with favorite fall annuals.
- Scheduling your fall garden cleanup. We’ll start preparing the landscape for winter once most of the leaves come down in November.
Other Tasks in the Organic Garden This Month
- 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.
- 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.
