Frosty Berseem Clover is a cool-weather cover crop known for its nitrogen fixation ability and cold-tolerance. As the name “frosty” suggests, this variety of clover is much more cold-tolerant than its Crimson and White Dutch relatives. Studies have shown that it can be cold-tolerant down to even single-digit temperatures in some regions.
In addition to improved cold-tolerance, Frosty Berseem Clover also has great nitrogen-fixation ability than other clovers. It has been reported to fix up to 150-200 lbs per acre when grown as a cover crop. It also germinates very fast, providing excellent weed suppression in a cover crop scenario. The flowers have a very low hard seed count, so there’s little risk of this variety becoming a weed in the future.
Frosty has foliage with oblong-shaped leaves that are larger than most clover varieties. As opposed to other Berseem clovers, Frosty is a multi-cut variety that can be foraged or cut multiple times, and it will continue to regrow throughout the cool season. The deep roots of this cover crop break up hardpans and make soils more workable over time. Those deep roots also scavenge and recycle nutrients, making them available for the following vegetable crop.
Clover should be planted in the fall a month or two before the average frost date. This will allow enough time for the clover to grow and establish ground cover before cold temperatures arrive. In a vegetable garden situation, clover should be cut before going to seed. This will prevent any weed issues in the following years. To remove clover in spring, it can be mowed or grazed. We suggest using chickens, goats, or other livestock to graze the clover while adding additional nutrients to your garden soil. If mowed, clover can be tilled into the soil immediately to add organic matter or “green manure”. It can also be mowed and left on top of the soil to suppress weeds until planting time.
