Fall frost and season extension

The first fall freeze usually arrives around November 20. There's a 1-in-10 chance it comes before November 4. Harvest tender crops such as basil, tomatoes, peppers and squash before then, or cover them on cold nights. Cool-season crops like kale, cabbage and Brussels sprouts handle light frost, and often taste sweeter after it. A hard freeze (28°F) typically comes around December 5.
