March around here means three things at once: dirt under fingernails, seed trays on every windowsill, and weather that flips its mood twice a day. Here is what we put where.
Direct sow
Peas in the first week the ground unfreezes. Spinach and lettuce a week later — they would rather be cold than warm. Radishes and carrots once we are sure the daytime stays above 50.
Indoor starts
Tomatoes, peppers, and basil go under lights mid-March. We have learned the hard way that too-early starts make leggy seedlings and a lot of February resentment.
What we skipped
Eggplant. Our season is too short and we are not running a greenhouse yet. Maybe next year. Probably not.
If we get one week of “oh no it is too cold to put the peas in,” we know we got the timing right.
