Frequently Asked Questions

How do I manage early blight or septoria leaf spot on Solanum lycopersicum (tomato) 'Ace 55'?

Early blight and septoria leaf spot show up as dark spots on older leaves, often moving upward as humidity rises. Remove and discard infected lower leaves, avoid overhead watering, and water at the soil line so foliage stays dry. If spots keep spreading, spray according to the label with a tomato-safe fungicide (e.g., chlorothalonil or copper-based products) beginning at first symptoms and repeating as directed.

How often should I water 'Ace 55' tomato during peak growth to prevent blossom-end rot and cracking?

During the main growth and fruit-set phase, keep soil consistently moist with about 1–2 inches (2.5–5 cm) of water per week, increasing during hot spells. Water deeply so moisture reaches several inches down, then let the top 1 inch (2.5 cm) of soil dry slightly before watering again—this steady pattern helps prevent blossom-end rot. Mulch around the plants to reduce swings in soil moisture that lead to fruit cracking.

When is 'Ace 55' tomato ready to harvest?

Harvest when fruits reach full size and the skin turns its mature color, typically starting around 70–85 days after sowing/planting depending on conditions. Pick when the fruit is firm but gives slightly to gentle pressure, and stop harvesting only when the plant is finished producing or gets hit hard by disease. For best flavor, harvest in the cool part of the day and let any slightly underripe fruit finish coloring indoors.
