I planted my plants by June 21, the deadline (I think around the 18th). I had an old decayed bag of coffee grounds. Two days afterward, my plants started dying. I lost four zucchini, and now one of my best tomato plants which is about 6 ft tall, looks like it is all but dead. What can I do? Please help!

Not much can be done to stop the tomato diseases. Unfortunately, they can occur at any time. Most years, it will not be a problem, as long as you practice good crop rotation.
