Frequently Asked Questions

What’s a common disease for Solanum lycopersicum (tomato) and what should I do if it shows up?
A frequent problem is early blight, which causes brown, concentric “target” spots on older leaves and can rapidly defoliate plants. Remove and discard affected leaves, avoid splashing soil onto foliage, and water at the base of the plant. If the disease is spreading, apply a labeled fungicide for tomatoes and reapply according to the product directions (especially after wet weather).
How can I tell when Pruden's Purple tomato (Solanum lycopersicum) is ready to harvest?
Harvest when the fruit is fully colored (purple/near-black shoulders with a ripe red/pink gel inside depending on your strain) and gives slightly to gentle pressure. The best indicator is that the fruit comes off the vine easily with a light twist and looks glossy rather than matte. For peak flavor, pick at a consistent ripe stage—once mostly ripe, let it finish on the vine for only a short time and avoid over-drying on hot days.

Sowing Tips

Soil Temperature

Direct sow or transplant when soil at planting depth holds 60°F for reliable germination and early growth.

Expert Note

For beefsteak types, transplant only when nighttime temps stay safely above ~50°F and the soil is near 60°F+ to avoid cold-stress and delayed set.
