Maximize your garden productivity with our harvest predictor. Calculate expected yields, harvest windows, and total seasonal production for all your vegetables based on plant counts and care level.
💡 Note: Indeterminate varieties produce more over longer period
Knowing when and how much you'll harvest helps with meal planning, preservation scheduling, and avoiding waste. Our harvest calculator uses plant count, variety, and growing conditions to predict yield and harvest timing. This information helps you plant the right amounts—3-4 tomato plants feed a family, while you might need 50+ lettuce plants for continuous salads.
Days to maturity (listed on seed packets) are estimates from transplanting, not from seed starting. Add 6-8 weeks for tomatoes/peppers started indoors, 1-2 weeks for direct-sown crops. Cool weather slows growth; heat speeds it. Our calculator adjusts for your climate zone and planting date to provide realistic harvest windows. Bush beans mature in 50-55 days; pole beans take 60-70 days but produce longer.
Succession planting prevents feast-or-famine harvests. Plant fast-maturing crops (lettuce, radishes, beans) every 2-3 weeks for continuous harvest rather than one overwhelming week. Our calculator suggests second and third planting dates based on days to maturity and your first frost date. For example, plant lettuce from early spring through early June, then resume in August for fall harvest.
Maximizing yields requires proper care: consistent watering (1-1.5 inches weekly), timely fertilization, pest management, and harvesting at peak ripeness. Many vegetables are "cut-and-come-again"—regular harvest encourages continued production. Pick zucchini at 6-8 inches (not baseball-bat size), harvest beans every 2-3 days, cut lettuce outer leaves for regrowth. Frequent picking keeps plants productive rather than switching to seed production mode.
Each vegetable has specific indicators: tomatoes are fully colored and slightly soft; cucumbers are dark green and firm (6-8 inches); lettuce leaves are 4-6 inches; beans snap cleanly when bent. Our calculator provides days to maturity estimates, but visual inspection and taste testing determine actual readiness.
Yields vary based on growing conditions, care, and variety. Our estimates assume good conditions: adequate water, fertilization, pest control, and proper harvesting. Poor conditions reduce yields; excellent conditions may exceed estimates. Track actual yields yearly to refine your planning.
Yes, through succession planting (plant every 2-3 weeks), season extension (row covers, cold frames for frost protection), and variety selection (early, mid, and late-season varieties). Our calculator suggests multiple planting dates for continuous harvest rather than single large harvests.
