Growing Tips, Tricks and FAQs
Growing Tips
Choose a sunny location with fertile, well-draining soil. Water consistently to keep the soil evenly moist but avoid oversaturation. Kentucky Beefsteak tomatoes are indeterminate and benefit from staking or caging to support their large, heavy fruit. Prune lower leaves and suckers for better air circulation and plant health.
When to Grow
Start seeds indoors 6-10 weeks before the last frost date in your area. Transplant outdoors once the risk of frost has passed and temperatures stay above 60 F. Look up your local last frost date to time planting.
How to Sow and Plant
Sow seeds 1/8 inch deep in seed-starting mix indoors, maintaining a temperature of 70-80 F for optimal germination. Provide 12-16 hours of light daily using grow lights or natural sunlight. Gradually harden off seedlings for about a week before transplanting outdoors. Space plants 24 inches apart in rows spaced 3-4 feet apart.
How to Grow
Water deeply once or twice a week, adjusting based on the amount of rain, and use mulch to retain soil moisture. Apply a balanced fertilizer at planting and switch to a phosphorus-rich fertilizer when fruiting begins. Provide sturdy support such as cages or stakes for the heavy fruit. Regularly remove suckers and yellowing leaves to improve airflow and direct energy to fruit production.
How to Save
- Most tomatoes are self-pollinating and don't frequently cross; in a garden setting, separating by 25 feet should prevent 99% of cross-pollination. Or you can bag and hand pollinate for 100% purity.
- On a small scale, seeds may be scooped from the fruits and dried on a paper towel.
- For larger quantities or cleaner seeds, fermentation for a few days is recommended.
- Once dry, tomato seed can be stored in a cool, dry, dark place; good seed retains viability for 5 years or more.
