I planted tomato plants in an old horse trough with holes in the bottom. I filled it w aged horse manure, the tomatos did very well, but the water drained out quickly. Not one to leave success to continue, I "helped" them by putting a layer of rich dense soil on top and then a layer of hay. I watered, then we had several days of rain. The plants promply went into shock. They wilted, leaves turned yellow. One of them is now perking up, new shoots/blossoms. The other one continues to wilt and yellow.
Is this an over watering problem? Should I do anything?
