Why are my plants wilting?

If the problem is caught early, it is possible that only a few plants have wilted so far. Wilting starts at the very tops of the plants. Before they visibly wilt, the leaves appear dull in color and have a "rubbery" feel to them. Full sized plants need 2 to 3 quarts of water per plant per day on sunny days. Other possible causes: 1) Check to see if the wilted plants have a broken stem; 2) Check the emitter at the base of wilted plants. It may be clogged and can be easily cleaned out; 3) Check for disease symptoms, i.e. a brown lesion at the base of the stem, brown vascular area inside the stem, etc. You may need help from your Extension Agent for this. 4) Be sure you have not overfertilized to the point that EC in the root zone has built up to high levels.
