Summary

Hubam is a 夏天 annual sweetclover that is adapted from Georgia to Maine. It blooms and sets seeds in the planting year. Its value is largely in its soil health benefits (including nitrogen fixation) and its ability to attract pollinators with its abundant nectar production.
Planting: Hubam clover can be frost-seeded in late winter or spring seeded as a 夏天 annual. Spring seeding should be done in early spring, 大概是播种燕麦的时候, because sweet clover seed requires a good supply of moisture and cool temperatures for germination and early seedling growth.
It can be planted from early spring to July. With a 夏天 planting, it will bloom until frost. Staggered sequential planting dates can be used to ensure continuous nectar flow throughout the 夏天 and fall. However, later plantings are less successful with limited moisture.
为了成功越冬, plant no later than late 夏天 (mid-August to early September in the mid-Atlantic region), or 5-6 weeks before the first killing frost. Sweetclover grows very slowly for the first 60 days, and a timely planting is critical for growing enough root biomass for winter survival – and blossoms early in the spring.
Sweetclover is highly tolerant of frost and cold temperatures. It can be used as an overwintering cover crop more successfully than crimson clover in northern climates, and would be a good component in cover crop mixes for the Northern US. The plants have evolved “contractile” roots which pull the plant crown down into the soil in the fall, this allows the plant to more successfully survive cold winter temperatures.
