Frequently Asked Questions

What pest or disease problem is most common on Solanum lycopersicum (tomatoes) and how do I treat it at home?

In tomatoes, early blight (Alternaria) often shows up as dark, concentric rings on older leaves. Remove and discard the infected leaves, improve airflow with wider spacing, and water at the soil line (not the foliage). If new spots keep appearing, spray an appropriate labeled fungicide for tomatoes and reapply according to the label, especially after rainy or humid stretches.

How often should I water Siletz tomatoes during the main growing phase?

During active vegetative growth and fruit set, keep the root zone evenly moist—about 1–2 inches of water per week total, adjusted for rainfall and heat. Water deeply 1–3 times per week rather than frequent light watering, and stop when the soil stays evenly damp but not soggy. If you see cracking or blossom-end rot, it’s usually from inconsistent moisture—switch to a steady schedule.
