It would be nice to know why your tomato plant seedlings are falling over so you can sort the problem and get them back to growing correctly.This is a common problem that most gardeners experience when growing tomatoes seedlings. We will take a closer look at things that make your tomato plants fall over.
The most likely cause of young seedlings falling over is the lack of light or damping-off caused by a fungus attack. Damping-off is a plant disease known to weaken or kill seedlings. It is caused by a fungus commonly found in wet and cool soil.
Your seedlings might not show any signs of damping-off but still suffer from falling over. In this case, lack of enough light could be the reason why they are falling over.
Root damage: happens during transplanting if seedlings grow too close together and their roots get tangled up. Lack of hardening off: they are likely to go into shock when they are outside.
-Prune your Tomato Vines: As your tomato plants grow they produce many suckers, which develop into large branches with leaves.
-Support your Tomatoes: You can use stake, trellises, or cages to support your plants.
