Adding a layer of mulch (such as straw, wood chips, or bark) helps retain moisture, suppress weeds, and provide nutrients as it breaks down.
Cover Cropping
Planting cover crops, like clover or rye, during the off-season keeps the soil covered and reduces erosion. These crops also improve soil structure and add organic matter when tilled under.
6. Incorporate Soil-Friendly Techniques
While it’s vital to amend your soil and adopt sustainable practices, certain techniques can also enhance soil health.
Minimize Soil Disturbance
Limiting tillage helps maintain soil structure and biodiversity. Instead of traditional tilling, consider no-till gardening, which protects beneficial organisms and promotes moisture retention.
Water Wisely
Overwatering can lead to soil compaction and nutrient leaching. Use drip irrigation or soaker hoses to water plants efficiently, ensuring moisture reaches the root zone without oversaturating the soil.
7. Monitor and Adapt Your Practices
Improving your garden soil is an ongoing process. Regularly monitoring your soil condition and adjusting your practices based on its needs will ensure continued success.
Seasonal Checks
Every season, conduct soil tests to track changes in pH and nutrient levels. Adapt your amendments and practices accordingly to maintain soil health year-round.
