I have black spots on some of my tomatos, and my cucumber leaves have yellow spots on them. What can I put on them. I assume they have some kind of bugs on them, but am not sure...Advice??

Try adding a couple tsp epson salt per gallon of water and use 1 or 2 times per week. The magneseum from the epson salt helps with blosson end rot.

If you hae them mulched, you may try pulling the mulch back to allow the soil to air and dry out a bit. Tomatoes and cukes like hot dry weather to produce. At least they like the air around them to be less humid than it has been.

This weather has not been the best . Hate to see so much hard work as a garden go to waste! Good luck. Let me know if this helped you?
