Zone 7 · March · 2 weeks before last frost
What to plant in March in Zone 7
Typical last frost in zone 7 is around Apr 1, and first frost around Oct 25. This is the month the season splits: cold zones are still starting seed indoors, warm zones are harvesting spring greens and setting out their first tomatoes.
Start indoors this month
Seed trays indoors, under a light or in the brightest window you have. These are slow crops that need a head start on the season.
- Cherry Tomato — window Feb 18 – Mar 4 (5 gal, 12" deep)
- Loose-leaf Lettuce — window Mar 4 – Mar 18 (2 gal, 6" deep)
- Basil — window Feb 18 – Mar 4 (2 gal, 8" deep)
- Kale — window Feb 25 – Mar 11 (3 gal, 10" deep)
- Bush Cucumber — window Mar 11 – Mar 25 (5 gal, 12" deep)
- Zucchini — window Mar 11 – Mar 25 (7 gal, 14" deep)
- Spinach — window Mar 4 – Mar 18 (2 gal, 6" deep)
Set out into the final container
Transplants go into the pot they will finish in. Hardening them off for four to five days first prevents most transplant shock.
- Kale — window Mar 18 – Mar 28 (3 gal, 10" deep)
- Strawberry — window Mar 4 – Mar 14 (2 gal, 8" deep)
- Spinach — window Mar 11 – Mar 21 (2 gal, 6" deep)
Direct sow
Sow straight into the final pot. These crops resent root disturbance, and transplanting them usually costs more time than it saves.
- Loose-leaf Lettuce — window Mar 11 – Apr 1 (2 gal, 6" deep)
- Radish — window Mar 11 – Apr 1 (1 gal, 6" deep)
- Kale — window Mar 18 – Apr 8 (3 gal, 10" deep)
- Spinach — window Mar 4 – Mar 25 (2 gal, 6" deep)
- Carrot — window Mar 18 – Apr 8 (3 gal, 12" deep)
Sow for autumn
A second sowing timed backwards from first frost. Fewer pests, less watering, and better flavour in most cool crops.
No autumn sowing window opens this month in this zone.
Harvesting this month
Nothing from our dataset is in its harvest window this month here.
Not this month
Everything in the dataset is either in an active window or already finished for the year. Nothing is badly timed this month.
Zone 7 at a glance
Zone 7 has around 180 frost-free days and a real summer. The limiting factor is July heat, not season length, so shading and watering matter more than sowing dates.
