What to Do When Fertilizer Burns Plants: Can They Be Saved?
Washing the roots and repotting: Promptly take the over-fertilized flowers out of their pots, then rinse the roots clean, and cut off the damaged roots and the dried, yellowed branches and leaves, while preparing new soil and a pot for the flowers. Watering thoroughly: Water the flowers immediately, watering until the water runs through and drains out, so as to flush the potting soil and wash out the high concentration of fertilizer; afterward, observe the flowers or take further measures.
