Troubleshooting
Principe Borghese Tomato problems — and how to fix them
Principe Borghese Tomato (Solanum lycopersicum 'Principe Borghese') 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.
Catfacing in cool set
Cold nights at flowering distort small fruit; wait for settled warmth before transplanting.
Determinate concentrated harvest
Much of the crop ripens together, so plan drying or processing for the flush rather than expecting season-long pickings.
Early blight
Concentric brown leaf spots in warm humid weather; mulch to stop soil splash, water low and remove lower leaves.
Blossom drop
Flowers abort in heat above 32°C or drought stress; keep moisture steady and provide afternoon relief in hot climates.
