Crimson Clover Seeds
When should I plant
Crimson clover is a cool-season annual legume best planted in late summer to early fall (August to October, depending on your climate) for winter growth and spring blooming. In milder climates, it can also be planted in early spring (February to April) for late spring to early summer flowering. Fall planting allows the plant to establish before frost, while spring planting may result in shorter growth before summer heat sets in.
Site consideration
Crimson clover thrives in well-drained soils with a pH between 6.0 and 7.0. It performs best in full sun but can tolerate partial shade. Avoid waterlogged or highly compacted soils, as this can hinder root development. It is often used as a cover crop, forage, or ornamental plant in gardens, roadsides, and fields.
Water
Keep the soil consistently moist but not waterlogged during seed germination and early growth. Once established, crimson clover is moderately drought-tolerant but benefits from occasional watering during prolonged dry spells. Overwatering can lead to root rot, so ensure proper drainage.
Sunlight
Crimson clover prefers full sun (at least 6–8 hours of direct sunlight per day) for optimal growth and flowering. It can tolerate partial shade, but flowering and biomass production may be reduced in low-light conditions.
Seed Germination
Seeds typically germinate within 7–14 days under optimal conditions (soil temperatures between 50–68°F). Lightly covering seeds with ¼ inch of soil improves germination rates.
Seeding Rate
For cover cropping or forage, sow 15–20 lbs per acre. For smaller garden plots or ornamental use, a rate of 1-2 lbs per 1,000 sq ft is sufficient. Broadcasting seeds and lightly raking them into the soil ensures good seed-to-soil contact.
Other Elements
Fertilization
Crimson clover fixes its own nitrogen, so additional nitrogen fertilizer is unnecessary. However, if soil fertility is poor, a balanced fertilizer (e.g., 5-10-10) or phosphorus/potassium supplement can aid establishment.
Weed control
Young crimson clover can face competition from weeds. Pre-emergent herbicides or light tillage before planting can reduce weed pressure. Once established, crimson clover forms a dense canopy that suppresses weeds. Mowing or hand-weeding may be needed in early stages if weeds become problematic.
Seed Storage
The seeds will maintain a high germination percentage if stored under proper conditions. How long your seeds remain viable will depend on the temperature and moisture levels the seeds are exposed to. Seeds which are improperly stored will quickly deteriorate if unprotected against high humidity and dramatic temperature fluctuations day after day.
For best results, keep the seed in our moisture-proof ziplock sealing bags, which provide a better moisture prevention effect. Glass jar or plastic containers with snap-on lids works well too, add a packet of desiccant before sealing into the seed, such as silica gel to remove any moisture remains in the storage container. Seed stored under these conditions will remain viable for as long as years.
Factors Which commonly Cause Poor Results
1. Improper drainage soil
2. Sowing depth more than one inch
3. Covering the seed too deep beneath the soil surface
4. Cover a large area with a small amount of seed.
5. Plant at a wrong time of a year
6. Lack of sunlight
7. Inadequate rainfall after seed germination. The area should not be allowed to become completely dry. Supplemental watering may be required to sustain plant life.
8. Extreme weather conditions: hail, drought, excessive rainfall, floods, unseasonably cold temperatures.
