What to plant in March in Zone 9

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.

Nothing in our dataset needs an indoor start this month in this zone.

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.

• Cherry Tomato — window Mar 8 – Mar 18 (5 gal, 12" deep)
• Loose-leaf Lettuce — window Mar 1 – Mar 11 (2 gal, 6" deep)
• Basil — window Mar 15 – Mar 25 (2 gal, 8" deep)
• Bush Cucumber — window Mar 8 – Mar 18 (5 gal, 12" deep)
• Zucchini — window Mar 8 – Mar 18 (7 gal, 14" deep)
• Hot Pepper — window Mar 15 – Mar 25 (3 gal, 12" deep)

Direct sow

Sow straight into the final pot. These crops resent root disturbance, and transplanting them usually costs more time than it saves.

• Bush Bean — window Mar 8 – Mar 29 (3 gal, 9" deep)
• Loose-leaf Lettuce — window Feb 8 – Mar 1 (2 gal, 6" deep)
• Radish — window Feb 8 – Mar 1 (1 gal, 6" deep)
• Kale — window Feb 15 – Mar 8 (3 gal, 10" deep)
• Bush Cucumber — window Mar 8 – Mar 29 (5 gal, 12" deep)
• Zucchini — window Mar 8 – Mar 29 (7 gal, 14" deep)
• Carrot — window Feb 15 – Mar 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

• Radish — harvest from Mar 8 (1 gal, 6" deep)
• Spinach — harvest from Mar 25 (2 gal, 6" deep)

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.
