What to Plant in February in Zone 8

A Curd That Needs Cool Weather

Cauliflower opens on the table for the first time this year this month, and the timing isn't arbitrary. The head needs a long run of cool days, generally 50 to 75 of them, to form a tight, white curd instead of the loose, grainy heads you get once temperatures climb past roughly 68 degrees and curd formation stalls. February is the last month here cool enough to start that clock for a spring crop.

Miss this window and the spring planting doesn't get a second attempt; a few weeks' delay pushes curding into heat the plant can't work around. A fall crop does return later from an August transplant, but that's a separate planting six months out, not a spring do-over.

Cabbage and broccoli both open this month too, and both tolerate a light frost on young transplants without protection, part of why February works here at all when it wouldn't in a garden with a harder late-winter freeze.

The Table Nearly Quintuples

Overall the crop count jumps from single digits to nearly 50 this month as peas, potatoes, and most of the cool-season lineup open at once. Meanwhile parsnip, leek, onion bulb, and cauliflower itself are all on their last call, since each needs a long enough season that a March start would run straight into early heat before finishing.

Peas germinate reliably once soil holds 45 degrees at a 2-inch depth for a few consecutive days; check with a soil thermometer rather than guessing from air temperature, which swings faster than the ground does.

Onion sets planted now should sit with the pointed tip just at the soil surface, not buried. A set planted too deep often forms a thick neck instead of a proper bulb by summer.

Spinach and arugula both germinate in soil as cool as 40 degrees, making them two of the most forgiving seeds to start this early. A patchy first sowing can simply be resown two weeks later with little lost.
