Fall gardening in New Hampshire doesn’t have to end when temperatures drop. Many leafy greens actually taste better after experiencing a light frost, becoming sweeter and more flavorful.

6. Collard Greens – Ultimate Winter Survivor
Collard greens laugh at cold weather that would kill less hardy plants. These incredible survivors can handle temperatures down to the upper teens, making them perfect for New Hampshire’s harsh conditions.
Frost actually improves their flavor, converting starches to sugars for sweeter, more tender leaves. Plant them in late summer for best establishment before winter arrives.
