Black Tomato Leaves?
Question:I have a Sweet Million cherry tomato plant in a pot, which I got at the end of March. It's done very well, but recently I've encountered a problem. The leaves closest to the sun (it's on a balcony) have turned black. They aren't wilting, it's not spots and it doesn't look like a fungus. The leaves just turn black, then the stem turns yellow and dies. I have no idea what it is. About 1/3 of my plant's leaves have turned black - the others are fine and don't appear to have any problems.
I heard it might be a problem with fertilization, but I've never fertilized it, and I've had it for months, so I don't understand how that could be it.
Anyone have any ideas?
Answers:
If the leaves are not wilting or turning brown, we can probably rule out sun scorching.
Black is the word that worries me, generally if you've got black on your leaves you have disease. I would not eat any tomatoes until you find out what is doing this. Pay very close attention to your tomatoes, inspect them and look for anything unusual, this could help you in figuring out what is happening.
If the leaves are actually more of a purple color, it could be cold temperature stress. Have you had any cool nights (below 55 degrees F) that would have possibly caused the damage?
I'm having this problem also. I don't think it's fertilization. Probably a fungus or disease. I don't think there is much we can do about it. May have something to do with excess moisture as we've gotten lots of rain where I am in TX.
It is usually called Blight - To cure this, you need to take one tablespoon of Clorox Bleach, and put into one gallon of water!
Pour around plants at least six inches from the base of plants, it should clear right up!
