Lemon Boy Tomato

Start seeds indoors 6-8 weeks before your last spring frost. Sow seeds about 1/4 inch deep in seed-starting mix kept at 70-75°F, maintaining consistent moisture but not waterlogged conditions. Provide bright light once seedlings emerge, and keep them under grow lights or in a sunny south-facing window.

Transplant seedlings outdoors after the last frost date when soil temperature reaches 60°F or higher and nighttime temperatures stay above 50°F. Harden off seedlings by gradually exposing them to outdoor conditions over 7-10 days. Space plants 24 inches apart in rows 36 inches apart, planting deep if desired to encourage a stronger root system.

Pick Lemon Boy tomatoes when they've turned a deep golden yellow throughout, this is the key indicator of ripeness, as the color shift signals peak flavor development. Gently twist and lift the fruit from the vine, or use pruners if needed. Fruits are ready roughly 70-79 days after transplanting, and regular harvesting encourages continued production throughout the season.

As an indeterminate variety, Lemon Boy will benefit from selective pruning to manage its sprawling growth and improve air circulation. Remove the lowest 6-12 inches of foliage as the plant grows to prevent soil-borne disease splash, and consider removing some interior branches once the plant is well-established to allow light penetration and reduce humidity-related issues.
