Zone 3 · June · 2 weeks after last frost
What to plant in June in Zone 3
Typical last frost in zone 3 is around May 30, and first frost around Sep 15. Everything is in the ground. Work shifts from sowing to staking, feeding and watering — and to planning the autumn crop.
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 Jun 6 – Jun 16 (5 gal, 12" deep)
- Loose-leaf Lettuce — window May 30 – Jun 9 (2 gal, 6" deep)
- Basil — window Jun 13 – Jun 23 (2 gal, 8" deep)
- Bush Cucumber — window Jun 6 – Jun 16 (5 gal, 12" deep)
- Zucchini — window Jun 6 – Jun 16 (7 gal, 14" deep)
- Hot Pepper — window Jun 13 – Jun 23 (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 Jun 6 – Jun 27 (3 gal, 9" deep)
- Kale — window May 16 – Jun 6 (3 gal, 10" deep)
- Bush Cucumber — window Jun 6 – Jun 27 (5 gal, 12" deep)
- Zucchini — window Jun 6 – Jun 27 (7 gal, 14" deep)
- Carrot — window May 16 – Jun 6 (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
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 3 at a glance
Zone 3 has roughly 100 frost-free days. Anything that needs more than 75 days from transplant has to be started indoors early or bought as a plant — direct sowing a tomato here is a wasted season.
