Frequently Asked Questions

What disease is most likely on Solanum lycopersicum (tomato) and how do I control it in my garden?

Tomatoes (Solanum lycopersicum) are very prone to early blight (Alternaria), which shows as dark, concentric “target” spots on older leaves and can spread quickly in humid weather. Remove and discard infected lower leaves immediately, avoid overhead watering, and water at the soil line. Start a labeled fungicide early in outbreaks and repeat as directed on the label, especially after rainy or humid stretches.

How often should I water Solanum lycopersicum during the main growing phase?

During active growth and fruit set, keep the soil consistently moist but not waterlogged—about 1–2 inches (2.5–5 cm) of water per week depending on heat and soil. Water deeply 2–3 times per week rather than light daily sprinkling, and aim for even moisture to prevent blossom-end rot and fruit cracking. Use mulch to hold moisture, and check the top 1 inch (2.5 cm) of soil; if it’s dry at that depth, it’s time to water.

When is Dr. Wyche’s Yellow tomato ready to harvest?

Harvest when the fruits are fully colored for this cultivar and the skin gives slightly when gently pressed. Pick at first full maturity rather than waiting for over-softness, because uneven watering or hot spells can lead to splitting. For best flavor and shelf life, harvest in the morning and let any remaining green shoulders finish indoors only if needed.

Sun-warmed and honeyed, Dr. Wyche's Yellow delivers a luminous, golden slice with a gentle, sweet-tang balance and a juicy, tender bite. The fruit’s meaty flesh stays pleasantly firm for slicing, with a classic tomato fragrance that blooms as the sun lifts its color. Grow it for standout fresh slices and showy, golden-hued sauces that highlight its sunny character from garden to table.

Sowing Tips

Transplant Conditions

Wait until soil reaches 60°F and nights stay above 50°F before moving outdoors. Harden off for 10 days first.

Expert Note

Transplant when soil is reliably warm (≈60°F+), bury the stem to the lower leaves, and keep temps steady to avoid cold-stress on this beefsteak type.
