Frequently Asked Questions


My Solanum lycopersicum (tomato ‘Moonglow’) leaves are developing yellowing spots and the lower foliage is dying—what disease is this likely, and what should I do?
This pattern is often early blight or Septoria leaf spot (both common on Solanum lycopersicum). Remove and discard affected lower leaves, avoid wetting foliage when watering, and improve airflow with wider spacing and pruning of lower growth. Treat early with a labeled fungicide for tomatoes and repeat according to the product label, especially during humid periods.
How often should I water ‘Moonglow’ tomatoes during the main growing phase, and what soil moisture level should I maintain?
Water deeply enough to soak the root zone, typically about 1–2 times per week depending on heat, and more often during hot weather (check the soil moisture daily). Aim for consistently moist soil—about the top 1–2 inches should dry slightly between waterings, but not fully dry out. Irregular watering can trigger blossom-end rot, so use mulch to steady moisture.
How can I tell when ‘Moonglow’ tomatoes are ready to harvest?
Harvest when the fruits have fully developed their mature color (for most ‘Moonglow’ types, a uniform red) and feel firm but not hard. Check for a slight give when you gently squeeze; if they’re still pale or mostly green, leave them on the plant until they color evenly. Pick regularly once they start ripening to keep the plant producing through the 85-day season.

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

Warm soil is everything for melon—transplant only once the ground is reliably warm and protect from cool nights for the first week.
