If you have empty space in your garden after clearing early summer harvests, leaving the soil bare is one of the worst things you can do. Exposed earth dries out rapidly under mid August sun and leaves room for aggressive weeds to take over.

Planting a quick cover crop is the easiest way to protect bare ground. Cover crops shield the earth from heavy rain, keep soil temperatures low, and naturally add vital organic matter back into the ground before winter.

Here are three simple, fast growing cover crops you can seed right now in mid August to keep your soil alive and protected.

1. Crimson Clover for Natural Nitrogen

Crimson clover is a fast growing legume that works wonders for exhausted soil.

Its deep root system breaks up tough soil compaction while working with beneficial microbes to pull nitrogen out of the air and deposit it directly into the ground. Seeding crimson clover in late summer ensures your soil will be naturally rich and ready for early spring crops.

2. Field Radish for Deep Soil Aeration

If your garden beds suffered from heavy foot traffic or clay compaction over the summer, field radishes are the ultimate natural solution.

These fast growing root crops drive long taproots deep into the earth, breaking up hard subsoil layers naturally. When cold weather arrives, the radishes decompose right in the ground, leaving open channels for air, water, and organic matter to reach deep into the earth.

3. Oats for Rapid Ground Cover and Mulch

For quick coverage that suppresses weeds almost overnight, plain oats are ideal.

Oats germinate in just a few days, creating a dense green mat that shades out weed seeds and prevents soil erosion from late summer storms. Best of all, oats naturally winterkill during the first hard frost, leaving behind a smooth blanket of protective natural mulch for early spring planting.

Investing in the Life of Your Soil

Keeping something growing in your soil year round protects the delicate microbial ecosystem beneath the surface. Feeding the ground naturally between main crops builds rich, resilient earth for seasons to come.
