Description
Solanum lycopersicum ‘White Tomesol’ is an heirloom tomato variety appreciated for its unusual pale ivory to creamy-white fruits and mild, delicate flavor. The plants are indeterminate and moderately vigorous, typically reaching 1.6 to 2.2 meters in height, and benefit from staking or caging to support steady production. Fruits are medium-sized, round to slightly flattened, with smooth skin and soft, juicy flesh. The flavor is low in acidity, gently sweet, and subtle, making this variety well suited for fresh eating, salads, and light culinary applications where a mild tomato profile is desired.
This cultivar thrives in full sun and fertile, well-drained soil with consistent moisture and good airflow. It is valued for its ornamental appeal, reliable yields, and distinctive fruit color.
Start seeds indoors 6 to 8 weeks before the last expected frost date. Transplant outdoors after all danger of frost has passed and soil temperatures are consistently above 16°C to 18°C. In warm or frost-free climates, seeds can be sown from late winter to early spring for best performance.

Growing Tips
Use a heating mat to maintain soil temperatures at 75-85°F for optimal germination. Sow seeds 1/4 inch deep in sterile seed starting mix; do not direct sow into garden soil. Keep soil consistently moist but not waterlogged to prevent fungal issues and seed rot. Start seeds indoors 6-8 weeks before last frost date. Seeds do not require light for germination, but provide bright light immediately after emergence to prevent leggy seedlings. Use bottom watering to maintain steady moisture without disturbing seeds. Once seedlings emerge, reduce temperature to 60-70°F with bright light to promote stocky growth. Do not fertilize immediately; wait until first true leaves develop before transplanting into 3-4 inch pots. Bury stems up to lower leaves when potting to promote strong root growth. Harden off seedlings for 1-2 weeks in full sun before transplanting outdoors 1-2 weeks after last frost date when soil is warm. Plant 24-36 inches apart in full sun and provide support via staking or caging.
