What to plant in April in Zone 6

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.

• Loose-leaf Lettuce — window Mar 18 – Apr 1 (2 gal, 6" deep)
• Bush Cucumber — window Mar 25 – Apr 8 (5 gal, 12" deep)
• Zucchini — window Mar 25 – Apr 8 (7 gal, 14" deep)
• Spinach — window Mar 18 – Apr 1 (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.

• Cherry Tomato — window Apr 22 – May 2 (5 gal, 12" deep)
• Loose-leaf Lettuce — window Apr 15 – Apr 25 (2 gal, 6" deep)
• Basil — window Apr 29 – May 9 (2 gal, 8" deep)
• Kale — window Apr 1 – Apr 11 (3 gal, 10" deep)
• Bush Cucumber — window Apr 22 – May 2 (5 gal, 12" deep)
• Zucchini — window Apr 22 – May 2 (7 gal, 14" deep)
• Hot Pepper — window Apr 29 – May 9 (3 gal, 12" deep)
• Spinach — window Mar 25 – Apr 4 (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.

• Bush Bean — window Apr 22 – May 13 (3 gal, 9" deep)
• Loose-leaf Lettuce — window Mar 25 – Apr 15 (2 gal, 6" deep)
• Radish — window Mar 25 – Apr 15 (1 gal, 6" deep)
• Kale — window Apr 1 – Apr 22 (3 gal, 10" deep)
• Bush Cucumber — window Apr 22 – May 13 (5 gal, 12" deep)
• Zucchini — window Apr 22 – May 13 (7 gal, 14" deep)
• Spinach — window Mar 18 – Apr 8 (2 gal, 6" deep)
• Carrot — window Apr 1 – Apr 22 (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 Apr 22 (1 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.
