Tomato Leaves Curling Upward, Rubbery — Too Much Nitrogen from Fresh Manure

Upward Curling, Rubbery Leaves, Slow Growth = Nitrogen Overdose

You added sand and manure this year. If manure was fresh (not composted), it's pumping huge nitrogen — causing lush, weak, curled foliage and poor fruit set.

Why This Happens

• Excess N forces vegetative growth over reproduction.
• High night temps worsen pollination failure.

Fix: Restart in Clean Soil

• Plant new transplants or seeds in a different bed without manure.
• Use balanced fertilizer (e.g., 5-10-10) at planting.
• Mulch, water consistently.

Current Plants? Likely a Loss

They won't revert. Pull them, solarize or compost the bed, and replant correctly. You'll get tomatoes this season.
