If your plant needs fertilizer and you fertilize it, it usually takes
eight days for the fertilized plant to show signs of being fertilized. If
you over fertilize, the effect may appear sooner. If over fertilized and
you want to save the plant, stir in copious amounts of gypsum into the soil
and water profusely. This technique usually works with potted plants and
can also work if planted outside in well drained soil. It'll take time but
plants often restore their health.
Most of the cases of over fertilization I hear about is from users of
'Miracle-Gro.' I warn my students to not use it or any high nitrogen
fertilizer -or - if they do continue to use it, water with 1/2 teaspoon (the
little end of the plastic spoon that comes with Miracle-Gro) per gallon of
water every)(!) time they water the plant.
