About Crimson, Clover Seed, Clover Seed

The Crimson Clover is an attractive winter annual that can be planted fall or early spring and will protect and improve the soil. This good nitrogen fixer (70-150 lbs per acre per year) blooms showy crimson flowers in late spring that are an excellent source of nectar for bees. This variety inter-seeds well with grass, making it a great way to ready your vegetable garden for the spring or beautify a landscape! Not to be confused with the tough perennial clovers that can take over a meadow.

Before Planting

Clover benefits from an open, sunny site with a firm, well-drained seedbed. Test the soil, correct pH and phosphorus or potassium deficiencies before planting, and control established weeds without overworking the surface. Inoculate clover seed with the correct fresh rhizobium strain when the crop or compatible legumes have not recently grown there.

Planting

Clover is best direct-sown during its recommended seasonal window, when enough growing time remains for establishment. Broadcast or drill seed evenly, then roll or press the area to ensure firm seed-to-soil contact. Keep the surface moist until seedlings establish if rainfall is insufficient. These crops normally form a stand and are not thinned; use the separate seeding-rate guidance to control density.

Watering

Maintain moisture until clover forms a uniform stand. Established plantings usually need supplemental water only during extended dry periods; apply deeply and infrequently rather than keeping the surface constantly wet.

Fertilizer

Avoid routine nitrogen fertilizer on clover; healthy nodules normally supply the crop’s needs. Correct phosphorus, potassium, or pH deficiencies only as indicated by a soil test.

Harvesting

Clover readiness depends on use: graze or cut while vegetative for quality forage, mow at early bloom for biomass, or allow seed to harden only when deliberate reseeding is desired.

Tips

Keep clover weed-free while the stand establishes. Mow or terminate before unwanted seed set, and avoid cutting so low that the crown and growing points are damaged.

Pests & Diseases

Clover diseases vary by species, but Sclerotinia crown rot, anthracnose, powdery mildew, and root rots are common concerns. Patchy stand collapse or cottony crown growth warrants rotation. Select locally resistant cultivars, avoid cutting wet stands, and allow enough regrowth to prevent disease from overwhelming stressed crowns.

Watch clover for aphids, weevils, beetles, cutworms, and mites. Remove egg clusters and badly infested foliage, protect seedlings with collars, and avoid unnecessary broad-spectrum insecticides.
