When fertilizer burn occurs or is suspected, what is the best thing to do ASAP, if possible?

• A. Repeatedly water the area thoroughly
• B. Apply more fertilizer
• C. Ignore and watch
• D. Apply pesticide

Answer: (A)

Fertilizer burn happens when there are too many soluble salts in the soil, which draws water out of the plant roots and into the soil. The quickest remedy is to flush those salts away by watering thoroughly. This dilution and leaching reduce the salt concentration around the roots, helping the plant take up water again and recover.

Do this as soon as possible by giving a deep, soaking irrigation that wets the entire root zone and allows excess salts to move beyond the root area. For a potted plant, water until you see drainage from the bottom. For a lawn or larger bed, apply enough water to penetrate deeply and leach salts downward. After flushing, avoid adding more fertilizer until recovery is evident and the soil has reset; other actions won’t address the salt buildup, and pesticides won’t help with fertilizer burn.
