Zone 3 · July · 7 weeks after last frost
What to plant in July in Zone 3
Typical last frost in zone 3 is around May 30, and first frost around Sep 15. Peak heat. Cool-season crops fail now, warm-season crops need daily water, and the smart move is to sow the autumn crop in shade.
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.
No transplanting window is open this month here.
Direct sow
Sow straight into the final pot. These crops resent root disturbance, and transplanting them usually costs more time than it saves.
No direct-sowing window this month in this zone.
Sow for autumn
A second sowing timed backwards from first frost. Fewer pests, less watering, and better flavour in most cool crops.

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.
