My young big bog plants, about 10 inches tall, are twisting and curling at the top stems. Looking more like a vine. 90% of about 100 plants same spot as last year using all the right stuff as before. Leaves appear good, no spotting. What can it be? Help gary
Tomato Plant Curling
Certified GKH Gardening Expert
The twisting and curling exhibited on the stems of your tomato plant could be attributed to herbicide drift. Tomatoes are very sensitive to herbicides. Wind speeds as low as 5 mph can move herbicides up to a mile and tomato plants can be injured by concentrations as low as 0.1 ppm.
