I set out 44 plants. They were fine and in about a week I fertilized and composted them. In about a week or two I noticed a couple of them wilting. Overnight more wilted and now I probably have less than 12 plants left and I keep losing some every day. It seems I will lose all my tomatoes. This may be a factor. The squash plants I set out are now doing the same thing after fertilizing and composting. I notice there is an ammonia like smell in the soil when I pull up the dead plants. I wondered about the fertilizer or could it be that weed killer got into my compost mix? Puzzled
My Tomato Plants Are Wilting and Dying

It is possible that they are suffering from fertilizer burn if the fertilizer your used was too concentrated or, if organic, un-mellowed (as in raw manure).

In response to Heather, my tomato plants did all come from the same source. I raised them myself starting them in peat pellets. I can check with friends and neighbors that I gave plants to and see if they are having any problems. I raised about 200 plants and 14 varietues and it seems the problem is in all varieties. I pray that it is something that I did setting them out, rather than it being a systemic problem in the soil.
