I sprayed my lawn (hose-end sprayer) with a liquid lawn fertilizer
(20-3-4) and some over-spray probably got on a few potted tomato
plants. The area was heavily watered the day before.

The next day I noticed the tomato plants looked somewhat shriveled
without actually being wilted or droopy.

The fertilizer contained no herbicide or weed killer. Just 20%
nitrogen, 3% Phosphorus (Phosphoric acid) and 4% soluble potash.
Would something like this be harmful to tomato plants?


At the peak of summer, that much nitrogen fertilizer is bad for
anything. Plants are either trying to go dormant in the heat, or divert
energy to surviving the heat. Fertilizing with nitrogen-rich fertilizer
forces them into growth cycles, and stresses them out. Your lawn is
going to need a lot of extra water now, too. This is the wrong time of
the year to be fertilizing.
