Balcony Harvest

Zone 6 · August · 9 weeks before first frost

What to plant in August in Zone 6

Typical last frost in zone 6 is around Apr 15, and first frost around Oct 15. A transition month. Harvest is heavy, and anything you want to eat in October has to be sown now.

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 6 at a glance

Zone 6 gives about 160 frost-free days and is the easiest zone for container growing — long enough for peppers, short enough that midsummer heat rarely sterilises pollen.
