Growing Eggplant in Spokane
Spokane's Zone 6b inland Pacific Northwest climate differs significantly from Seattle's — less rain, more sun, and more extreme temperature swings. The Palouse region's continental climate means hot, dry summers ideal for tomatoes and peppers (a welcome contrast to rainy western Washington). The frost-free window of about 171 days is adequate for a wide range of crops when warm-season starts begin indoors in late March.
In Spokane (last frost around April 22), aim to direct sow or transplant eggplant outside around May — approximately 2 weeks after your last expected frost. Starting seeds indoors 8 weeks before the last frost date gives you a significant head start.
Eggplant 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 70–85 days from transplant to first harvest. Heat-loving. Similar to peppers.
