The leaves curled up on my tomato plants. Is there something I can add to the soil this winter? No poison.?

I heard it might be blight and adding sulfer to the soil now will help for next years crop. Is this truth or baloney? Is there something else I could add that is not toxic? Does adding sulfer make the tomatoes taste nasty?





Thanks for your time.

It's always a good idea to plant your tomatoes in a different patch each year - if you have the space available that you can "rotate" your crops, of course. Plant things that aren't suspectible to tomato problems in the spot where you planted your tomatoes this year.





Also - If it was the LOWER leaves curling up - that is a sign of overwatering.
Reply:Mature tomato leaves curl and there is nothing wrong. However, if you suspect blight, the biggest cause of blight is failure to mulch your plants heavily. When water or rain hits bare dirt, it bounces the soil up unto the undersides of leaves and the dirt contains blight, insect eggs, viruses, etc. If the dirt stays off the leaves, so does the blight for the most part. Also space your plants far apart leaving them lots of room to breathe and not touch each ohter. Next year, as soon as you put your plants into the ground, mulch heavily around the plants. You can also have a soil test done to see what you may lack in essential nutrients that a plant needs. Sulfur gets rid of alot of molds and blights but it also changes the Ph of the soil. There is no need to use sulfur unless you know that you have to. So yes, I think that adding sulfur to your soil is baloney.
Reply:sulfur will kill both good and bad microbes in the soil, best to spray top and under the leafs with a mild fungicide next year at the first sign of a problem
