Growing Tomatillo in Austin
Austin's Zone 8b climate is excellent for ambitious gardeners. With roughly 275 frost-free days, you can grow two full vegetable seasons and experiment with subtropical crops. The limestone-heavy soil benefits from amendment, but the long growing season more than compensates — tomatoes, peppers, and sweet potatoes all thrive here.
In Austin (last frost around February 24), aim to direct sow or transplant tomatillo outside around March — approximately 2 weeks after your last expected frost. Starting seeds indoors 6 weeks before the last frost date gives you a significant head start.
