Growing Sweet Potato in Rochester
Rochester's Zone 6a climate on Lake Ontario's southern shore offers about 174 frost-free days. Lake-effect snow dominates winter, but the lake also moderates spring and fall temperatures, extending the usable season somewhat. Once warm-season crops go in after late April, Rochester summers are surprisingly productive for tomatoes, peppers, and cucumbers. Short-season varieties help ensure full harvests before October's first frosts.
In Rochester (last frost around April 25), aim to direct sow or transplant sweet potato 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.
