Troubleshooting
Paul Robeson Tomato problems — and how to fix them
Paul Robeson Tomato (Solanum lycopersicum 'Paul Robeson') 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.
Hard to judge ripeness
'Black' tomatoes stay dusky and never turn fully red, so growers pick too early or too late. Harvest when the fruit softens slightly and the shoulders deepen to a muddy brick tone.
Fruit cracking
Dark-shouldered beefsteaks split after irregular watering or rain following drought. Keep moisture even and pick ripe fruit promptly.
Blossom-end rot
Sunken patches on the fruit base from uneven calcium uptake driven by inconsistent watering. Mulch and maintain steady soil moisture rather than adding calcium.
Late blight
Brown blotches on leaves and stems in warm, humid weather can collapse the plant. Water at the base, space for airflow, and remove infected foliage early.
