Preparing Your Garden For Fall

Prepare your garden for fall by starting with soil health. Test your soil’s pH and nutrient levels. You can amend it with organic matter, such as compost or well-rotted manure, to enhance fertility.

Plant cover crops if your garden space sits empty. Consider options like clover or rye, which help improve soil structure and suppress weeds during winter.

Choose appropriate crops for fall planting. For instance, Brussels sprouts, garlic, and shallots thrive when planted in September. They require a longer growing season but yield excellent results.

Mulching offers several benefits. Apply a layer of organic mulch, like straw or shredded leaves, to retain moisture and regulate soil temperature. Mulch also suppresses weeds and adds nutrients as it breaks down.

Monitor weather conditions in September. Keep an eye on frost dates, as these will affect which crops succeed. If a frost threatens, be ready to cover your plants with row covers or blankets for protection.

Water your garden consistently. As temperatures drop, plants can still suffer from moisture stress. Check the soil regularly and water as needed, especially newly planted crops.

Stay vigilant against pests. Look for signs of infestations and use organic pest control methods when necessary. This helps maintain a healthy garden ecosystem through fall.

Harvest regularly. Regular harvesting promotes new growth in many crops, encouraging continuous production until the first hard frost.

Follow these steps to prepare your garden for fall and enjoy a fruitful season.
