Leaf burn due to over-fertilization.
Leaf burn is caused by over-fertilization. This is often visible by a few, sometimes many, yellow-green spots. Sometimes the spots are even completely white. The affected leaves turn yellow, turn brown and eventually wither.
Drought and summer heat can also cause leaf burn, but in that case the leaves wither, usually without turning yellow first.
Where to find
- Vegetable plot and ornamental garden
Control
In case of leaf burn due to over-fertilization, the plants sometimes recover during the season (the excess fertilizer is still absorbed). Remove affected leaves, place (pot) plant in a shady spot, water a lot.
Prevention
Follow the fertilizing directions on the seed and/or fertilizer package.
