PlantFertilizer burn.
Plant damage associated with excessive fertilizer or a high concentration of soluble salts around roots.
What it means for your plants
Review every feed source, dilution, and application before acting. Similar leaf damage can come from other causes. Avoid trying to correct suspected overfeeding by adding a different fertilizer.
IN PRACTICE
A concentrated solution mixed for a large watering can but applied undiluted can expose roots to an excessive dose.
Put it into practice
Recognize possible overfeeding, review overlapping fertilizers, and take measured steps when excess salts may be damaging a plant.
