The Best Winter Cover Crops for Zone 9

3. Hairy Vetch

Hairy vetch may be sown later than most other legumes and is winter hardy enough to thrive in locations where hard frost occurs. Hairy vetch produces a lot of greenery and has a strong root system when grown in the right conditions. It fixes a considerable quantity of nitrogen, supplying 100 pounds or more of nitrogen per acre to the following crop.

Hairy vetch residues break down faster than most other cover crops and release nitrogen more quickly. When a fast-growing, high-nitrogen-demanding crop follows hairy vetch, this can be advantageous.

4. Clover (Subterranean)

Most cultivars of subterranean clovers require at least 12 inches of rain during their growing season, growing close to the earth. These winter cover crops zone 9, add nitrogen to the soil and are great for loosening hard soils, weed control, and erosion management.

Sub clover is another name for these cool-season annuals.

5. Woolpod Vetch

This is a speciality vetch that grows more quickly than hairy vetch. It can also be cultivated in USDA Zones 7 and warmer as a winter cover.

It requires little or no irrigation and reliably provides copious nitrogen and organic matter while also acting as a weed suppressor.

6. Oats

Oats are annual grass that produces fast, weed-controlling biomass. They have a fibrous root system that scavenges the soil for nutrients, and when planted in mixes, they can increase the productivity of legumes.

These winter cover crops zone 9 are a four-foot-tall cool-season annual cereal grass. They’re also known as spring oats since they don’t grow well in hot, dry weather.

7. Rapeseed

This winter cover crops zone 9 is prized for its ability to manage both plant pathogenic nematodes and weeds. Because the plants can resist cold conditions, sow the seeds in early spring or late fall.


8. Rye (Grain)

Rye is the most commonly planted cover crop in the United States. It is considered the hardiest of the cereals because it can be sown later in the fall than other cover crops and still has time to establish an extensive root system that will prevent erosion and provide extensive nitrate leaching and exceptional weed suppression.

9. Wheat

Wheat, while best recognized as a cash crop, can also be used as a cover crop. It reduces erosion, controls weeds, scavenges excess nutrients, and adds organic matter to the soil when used for this purpose. As a winter annual, grow it.



These nine best winter cover crops zone 9 minimize erosion, improve the physical and biological qualities of the soil, provide nutrients to the following crop, inhibit weeds, increase soil water availability, and break insect cycles. Some of them also can break through compacted soil layers, allowing the roots of the next crop to develop more fully.
