Beefmaster

Blossom-end rot on Beefmaster shows up as dark, sunken patches on the blossom end and is driven by inconsistent moisture rather than a lack of nutrients. Water deeply and evenly (avoid letting the soil swing between wet and dry), keep mulch 2–3 in thick, and remove badly infected leaves early to slow fungal leaf spotting; improve airflow by spacing plants and pruning only the lowest heavily diseased foliage. If spotting spreads quickly in humid weather, start with a labeled copper or chlorothalonil spray at the first signs and repeat as the product label directs for tomatoes.

Harvest when fruits are fully colored for Beefmaster (deep red) and the skin is glossy and firm but yields slightly to gentle pressure. At 90 days from transplanting/sowing schedule, check your first clusters often—tomatoes can go from under-ripe to over-soft in just a few warm days. If you see a slight color change beginning at the shoulders, you can pick and let them finish ripening indoors at room temperature for a few days.
