Best Tomatoes to Grow in Washington

Zone 7 gardeners hit the tomato-growing jackpot with a generous 210-day growing season that runs from early April through late October. This extended season gives you the luxury of growing both quick-maturing varieties and long-season heirlooms that need extra time to reach their full potential. The key challenge you'll face is the intense summer heat that typically peaks in July and August, which can stress plants and reduce fruit set if you're not prepared.

When selecting varieties for Zone 7, prioritize heat tolerance and disease resistance, particularly for common issues like early blight and bacterial wilt that thrive in humid summer conditions. Look for determinate varieties if you want concentrated harvests for preserving, or indeterminate types if you prefer steady production throughout the season. The varieties I've selected below have proven themselves in Zone 7's climate, offering excellent flavor while standing up to both the spring temperature swings and summer heat stress that define this growing zone.
