Frequently Asked Questions


What should I do if my All American tomatoes develop gray mold or fuzzy gray spots on leaves and fruit?
Gray mold is often triggered by cool, humid conditions and dense foliage. Remove and discard affected leaves or fruit immediately, then thin foliage so air moves freely through the plant. Keep the soil evenly moist but avoid wetting foliage—water at the base and improve airflow with spacing or light pruning around the clusters.
How often should I water All American tomatoes during the main growing phase (from flowering through fruit set)?
Water about 1–2 inches per week total, aiming for deeper soaking 2–3 times per week rather than daily light sprinkling. Check by feel: the top few inches should dry slightly between waterings, but the root zone should not go dry. Inconsistent watering can lead to blossom-end rot and cracked fruit, so keep moisture steady once the first fruit sets.
How can I tell when All American tomatoes are ready to harvest at ~100 days?
Harvest when fruit is fully colored (deep red) and the surface feels firm but gives slightly to gentle pressure. The fruit should come off the plant with a slight twist—avoid tugging hard on green shoulders. For best flavor, harvest in the cool part of the day and let any fully colored fruit ripen off the vine if they picked slightly early.

Sowing Tips

Transplant Conditions

Expert Note

Direct-sow parsnip seed as soon as soil can be worked, keep it evenly moist until germination, and expect the best sweetness after a light frost.
