Using covers in spring for an increase in growth

Spring can challenge us with low temperatures which prevent new growth. Winter root vegetables are running out, and May is the hungry gap, between old and new harvests. Subtitles and translations by 3rd May Spring offers good light levels in its longer days, yet often lacks warmth. New plantings in cold weather may stay small, even struggle to survive.
