Growing tomatillos in zone 6

Plant at least two for cross-pollination or you’ll get husks with no fruit. Treat like a sprawling tomato: same timing, same staking, ready when fruits fill their papery husks.

Zone 6 covers mid-Atlantic, Ohio Valley, Kansas, inland Pacific Northwest — nearly 200 frost-free days — almost everything grows, and fall gardens are easy. Zone dates are medians: frost timing varies within a zone with elevation and terrain, so treat these windows as a solid default and refine them with your own city’s dates below.

Make it local

These windows use zone 6's typical frost dates (last frost ~Apr 10, first frost ~Oct 22). For windows computed from your frost dates, run the ZIP code frost lookup and open the planting calendar — it remembers your city. The seed starting scheduler turns the whole seed rack into one printable, date-sorted list.

Frequently asked questions

When do I plant tomatillos in zone 6?

Transplant Apr 17 – Apr 24, counted from zone 6's typical last frost around Apr 10. It has no frost tolerance — a late frost after planting means covering it or replanting.

When should I start seeds indoors for tomatillos in zone 6?

Sow indoors Feb 13 – Feb 27 — that's 8 to 6 weeks before the typical Apr 10 last frost, giving sturdy transplants exactly when the garden is ready for them.

Can I direct sow tomatillos in zone 6?

Not usefully in zone 6 — tomatillos needs more growing time than direct sowing allows, which is why it's raised from transplants started indoors Feb 13 – Feb 27.
