Troubleshooting
'Brandywine' Tomato problems — and how to fix them
'Brandywine' Tomato (Solanum lycopersicum 'Brandywine') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Low yields and late ripening
Brandywine is naturally a late, modest cropper; start seed early, give it the warmest spot, and be patient for the long maturity window.
Blossom-end rot
Large fruit are prone to sunken dark bases when moisture is uneven; water consistently and mulch rather than chasing calcium supplements.
Catfacing and irregular fruit
Cool temperatures during flowering cause puckered, misshapen beefsteak fruit; transplant only after nights warm and protect early flowers from cold.
Early and late blight
Fungal leaf and stem disease in damp weather; rotate crops, water at the base, space for airflow, and remove affected leaves promptly.
