Frequently Asked Questions
How many tomato plants should I grow per person?↓
Extension services recommend planting 2 to 4 tomato plants per person for fresh table eating throughout the summer, or 5 to 10 plants per person if you plan to can marinara sauce and salsa for winter storage.
What factors reduce actual garden crop yields below these estimates?↓
Extreme summer heat over 90°F / 32°C (which causes tomato blossoms to drop without setting fruit), inadequate pollinator bee activity, pest infestations (hornworms, aphids), and irregular watering (blossom end rot) can reduce yields by 30% to 50%.
Which vegetables produce the highest dollar return in a small garden?↓
Indeterminate vining heirloom tomatoes, bell peppers, fresh culinary herbs (basil, cilantro, rosemary), and gourmet salad greens deliver the highest financial savings compared to supermarket organic prices.
What is a limitation of average seasonal yield calculators?↓
Yields depend on the length of your local frost-free growing season; a gardener in Florida or California with 250 frost-free days will harvest significantly more per vine than a gardener in zone 4 with only 100 growing days.
