How to Choose Clover for Cover Crops

Crimson clover flower head in a field

The right clover depends on how long the planting should live, the season and climate, soil moisture and drainage, mowing or traffic, the following crop, and how the stand will be terminated. “Clover” is not one interchangeable cover crop: crimson, red, white, strawberry, subterranean, berseem, and clover mixtures can behave very differently.

Begin with the planting purpose, then compare current products in the Clover Seed collection. Product descriptions control the current variety, treatment, organic status, planting rate, and inoculant requirement.

Clover cover crops at a glance

Clover type Typical life cycle Common planning role Main management question
Crimson clover Annual Defined cool-season window, mixtures, and relatively early bloom Will it establish and survive long enough before termination?
Red clover Biennial or short-lived perennial Longer rotations, overseeding, and persistent living cover Does the following crop allow enough time and a suitable termination method?
White clover Perennial Low-growing living cover where mowing and competition are managed Can water, traffic, spread, and competition with the main crop be controlled?
Strawberry clover Perennial Low-growing or specialized sites where the selected variety is adapted Does the site match the product’s moisture, climate, and persistence requirements?
Subterranean clover Annual with potential reseeding Mediterranean-climate annual cover and living alleys Is reseeding wanted, and can the stand be managed before seed becomes a problem?
Berseem clover Annual Fast annual growth where its seasonal window fits Is there enough establishment time before cold or the next crop?

These are general growth patterns, not guarantees for every cultivar or climate. Verify local adaptation and the current product.

Choose by duration and the following crop

Use an annual clover when the cover has a defined end date and you do not want a long-lived crown competing with the next crop. A short-lived perennial or perennial can be useful for a longer rotation, a living alley, or a managed understory, but persistence increases the importance of mowing, irrigation, root competition, and termination.

Work backward from the following crop’s planting date. Include establishment, useful growth, termination, and residue management. A clover that survives well but cannot be terminated on schedule is not the right choice for that rotation.

Choose by climate and seasonal window

Winter survival depends on species, cultivar, establishment, snow or wind exposure, soil drainage, and actual temperatures. Do not treat “fall planted” as a universal promise of winter survival. In mild-winter climates, an annual may grow through much of winter; in colder climates, a more persistent species may still need early establishment to survive.

Use Fall Cover Crops for cool-season planning and Summer Cover Crops when considering a warm-weather annual window.

Choose by height, mowing, and traffic

Low-growing clovers may fit paths, alleys, or understories better than an upright annual, but “low growing” does not mean maintenance-free. Mowing height and frequency affect flowering, vigor, reseeding, and persistence. Traffic tolerance also depends on soil moisture and compaction; repeated traffic on wet soil can damage the stand and the soil beneath it.

In orchards and vineyards, keep competition, irrigation, frost, harvest access, and fire-season vegetation management in the plan. See Cover Crops for Orchards and Vineyards.

Raw, coated, Nitrocoated, and inoculated clover seed

These descriptions are not synonyms. Raw seed has no applied coating. Coated and Nitrocoated products may use different materials and treatments. A coating does not automatically mean that compatible living rhizobia are included. Read the current product listing and seed label.

For raw seed, use a clover-group inoculant that lists the planted species. Check expiration, storage, package coverage, application rate, and the allowed interval between treatment and planting. Use the Legume Inoculant Compatibility Chart and the rhizobia application guide.

Planting clover seed

Small clover seed generally needs shallow placement, good seed-to-soil contact, and dependable moisture through germination. Excessively deep placement, a fluffy seedbed, surface crusting, dry soil, or competition from established vegetation can produce a thin stand.

Measure the area with the Cover Crop Seed Rate Calculator, then enter the selected clover product’s current broadcast or drilled rate. Do not apply one clover species’ rate to another or add full single-species rates together when planting a mixture.

Plan termination before planting

Annual clovers can still set seed and volunteer. Perennial and short-lived perennial clovers can regrow from crowns or roots. Select mowing, cutting, rolling, grazing where appropriate, incorporation, or another method based on species and stage.

Red clover or crimson clover?

If the choice has narrowed to these two species, use the detailed Red Clover vs. Crimson Clover comparison. It preserves the narrower two-species decision while this guide covers the broader clover category.

Choose current clover seed

Browse Clover Seed, Legume Cover Crops, or Seed Inoculants. Do not infer certified-organic status from an approved coating or inoculant; rely on current certification information for the seed product.
