Fall frost and season extension
The first fall freeze usually arrives around November 1. There's a 1-in-10 chance it comes before October 18. 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 November 12.
