As the summer days wane and the crispness of fall begins to hint at the horizon, it’s time to focus on the September garden chores that will set the stage for a thriving garden in the coming months. Planting by USDA Zone provides a clear guide on what to plant and when, but pairing this with local knowledge and year-to-year observations will ensure your gardening success. Here’s a comprehensive guide to September tasks for each USDA Zone, including some eco-friendly tips to keep your garden in top shape.
Zone 4
1. Plant Cool-Season Crops: September is an excellent time to plant leaf lettuce, chard, spinach, and radishes. These hardy crops can still be planted for a fall harvest.
2. Pest Control: Keep an eye out for pests, particularly bean beetles which can make a strong comeback in late summer. Use Ecoworm Potassium Soap to manage pests naturally and effectively.
3. Bring Houseplants Indoors: If you’ve been keeping houseplants outside for the summer, bring them in before the weather gets too cold. Give them a thorough watering to remove any lingering insects. Inspect them daily for pests and treat as needed.
4. Mulch for Winter: Start preparing for winter by mulching your garden beds. While bagged mulch is convenient, ordering a truckload can be more economical. Consider splitting a load with neighbors if you have excess.
5. Transplant Perennials: Fibrous-rooted perennials should be divided and transplanted every 3-5 years. Fall is the best time for spring-flowering perennials, while fall-blooming plants like chrysanthemums should be divided in spring.
6. Harvest and Store Crops: Harvest pumpkins, summer squashes, and gourds before the first frost. Handle them carefully to avoid damaging the rind, which can cause quicker deterioration. Continue harvesting cool-season veggies like radishes, lettuce, and broccoli.
Zone 5
1. Fall Planting: You can still plant leaf lettuce, chard, spinach, and radishes for fall harvest. These cool-season crops thrive in September’s cooler temperatures.
2. Pest Management: Regular pest inspections are crucial, especially for bean beetles. Utilize Ecoworm Potassium Soap to keep pests under control without harming the environment.
3. Indoor Plants: Bring in houseplants that have been outdoors for the summer. Water them well to flush out any pests and check them frequently for new infestations.
4. Mulching: Prepare your garden beds for winter by mulching. If you need a large amount, consider sharing a truckload with neighbors to save on costs.
5. Transplanting Perennials: Divide and transplant fibrous-rooted perennials now. Cut back the tops to 4-6 inches to minimize transplant stress and ensure the new site is well-prepared.
6. Harvesting: Harvest pumpkins, summer squashes, and gourds before frost. Handle them gently to prevent damage. Keep up with the harvest of cool-season vegetables and consider the flavor enhancement that frost can bring to certain crops like Brussels sprouts and kale.
7. Soil Improvement: Fall is ideal for adding organic matter to your garden soil. Incorporate manure, compost, and leaves to boost soil health. Wood ashes can also be added as a top dressing for a nutrient boost. Consider adding Ecoworm Soil Extract to your soil.
Zone 6

3. Bring Houseplants Indoors: By mid-month, bring your houseplants inside. Water them thoroughly before bringing them in to remove insects. Inspect them daily for pests in the initial weeks.
4. Winter Preparation: Start mulching your garden beds for winter. Consider getting a truckload of mulch and share it with neighbors if needed.
5. Transplanting Perennials: Divide and transplant fibrous-rooted perennials now. Ensure you prepare the new planting site thoroughly and cut back tops to reduce stress.
