Frequently Asked Questions


What pest or disease most commonly affects Solanum lycopersicum (Hungarian Heart/oxheart tomatoes), and how can I stop it?
Watch for early blight (dark, concentric spots) and leaf spotting, which are common on Solanum lycopersicum in warm, humid spells. Remove and discard infected lower leaves, water at the soil line (not overhead), and keep plants well spaced for airflow. If problems persist, spray a labeled fungicide for tomatoes according to label intervals, starting at the first signs of spotting.
How often should I water Hungarian Heart tomatoes during the main growing phase?
During fruiting, keep soil consistently moist but not soggy—aim for about 1–2 inches of water per week, delivered in deep soakings. Water when the top 1 inch of soil dries out, and use mulch to reduce swings that cause cracking and blossom-end rot. Avoid frequent light watering, which encourages shallow roots and more stress during hot weather.
How do I know when Hungarian Heart tomatoes are ready to harvest?
Harvest when the fruit is fully colored (typically deep red), feels firm but not hard, and reaches the expected size for an oxheart shape. The blossom end should be firm with no dark, sunken rot, and the fruit should detach with a gentle twist once mature. For best flavor, wait until the fruit is ripe on the vine rather than picking early.

Sowing Tips

Transplant Conditions

Wait until soil reaches 60°F and nights stay above 50°F before moving outdoors. Harden off for 10 days first.

Expert Note

Start seeds warm, then harden off thoroughly and transplant only when night temps stay reliably ≥50°F to protect large-fruited plants from cold-stress.
