Frequently Asked Questions


What pest or disease is most common on Solanum lycopersicum (tomatoes) like ‘Green Giant,’ and how can I manage it?
A very common issue is early blight (Alternaria), which shows as dark, concentric spots on lower leaves that spread upward. Remove and discard infected leaves, avoid overhead watering, and improve airflow by spacing plants; for ongoing pressure, use a labeled fungicide that targets early blight and rotate products to prevent resistance. If you see rapid leaf yellowing and collapse, check for fungal wilt conditions and remove badly affected plants to protect the rest of the row.
How can I tell when Solanum lycopersicum is ready to harvest (around 85 days to maturity)?
Harvest when fruits reach full size and have a firm, glossy skin with a uniform green turning to mature color for your variety; taste should be sweet and tomato-like rather than tangy. For the best eating quality, pick by the stem at peak firmness—avoid waiting until the fruit is soft or splitting. If nights are cool or light is low, you may need to let fruits stay on the vine a bit longer, checking daily for color and firmness.
