Growing Tomatillo in Buffalo
Buffalo's Zone 6a climate on the eastern end of Lake Erie is famously influenced by lake-effect weather — heavy winter snows but also a moderated spring and fall. The frost-free window is about 161 days, among the shorter in this list. However, summer temperatures are comfortably warm for tomatoes and peppers when they finally arrive. Short-season varieties and indoor starting in early April are critical strategies.
In Buffalo (last frost around May 3), aim to direct sow or transplant tomatillo outside around May — approximately 2 weeks after your last expected frost. Starting seeds indoors 6 weeks before the last frost date gives you a significant head start.
Tomatillo thrives between 65°F and 90°F. It is frost-sensitive, meaning a single freeze at 32°F will damage or kill it — always wait until frost danger has fully passed. Expect 75–100 days from transplant to first harvest. Plant at least 2 for cross-pollination. Papery husks split when ready to harvest. Very vigorous grower.
