Frequently Asked Questions

What disease is most common on Solanum lycopersicum (Lemon Boy tomato), and how do I manage it?

A major problem is early blight (Alternaria), which shows as brown, target-like spots that often start on lower leaves and spread upward. Remove and dispose of infected leaves, keep foliage dry by watering at the soil line, and apply a labeled protective fungicide as soon as symptoms appear, repeating per the label. Improve airflow by pruning for open canopy and spacing plants so leaves don’t stay wet after rain or irrigation.

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

During active fruiting, keep soil evenly moist with about 1–1.5 inches (2.5–4 cm) of water per week, adjusting for heat and rainfall. Water deeply 2–3 times per week rather than light daily watering, and avoid letting the soil dry out completely because tomatoes like this can crack and suffer blossom-end rot. Aim for consistent moisture—mulch around the plant helps stabilize soil moisture.
