Tomato leaf problems

Question

I grow tomatoes in large pots.. Some of them are big, bushy, and producing lots of fruit. A couple of them, same type tomatoes, grown from seeds, same soil, same area of the yard, same care, are producing fruit, but all the foliage has turned brown and the leaves are all falling off. I examined them closely, I see no signs of bugs or anything. The fruit ripens, tastes good, a bit smaller than the others, but still good. Any idea what the problem is? I have moved those pots away from the others, ‘just in case’………help please? There is almost no foliage on these plants, and what little is still there doesn’t look like it will be for much longer.

Answer 1

This is typical of tomato wilt disease. Go ahead and harvest any tomatoes, then dispose of the plant in the trash. The soil should be thrown out. Make sure to wash the container thoroughly before planting again. Use a 10 percent bleach solution when cleaning the pot.
