When you notice the first symptoms of fire blight, such as wilting blossoms or blackening branches, it is crucial to take immediate action. The earlier you treat the disease, the better chance you have of preventing its spread and minimizing damage to your apple trees.

Here are some recommended steps for treating fire blight on apple trees:

Pruning: Start by pruning infected branches at least 12 inches below the visible signs of the disease. Make sure to sterilize your pruning tools between cuts to avoid spreading the bacteria further.

Disinfecting: After pruning, disinfect your tools with a solution of 10% bleach or rubbing alcohol to kill any remaining bacteria.

Spraying: Apply a suitable bactericide or antibiotic spray to the affected areas and surrounding healthy tissue. Follow the instructions provided by the manufacturer for the correct dosage and application method.

Preventive Measures: To prevent fire blight from recurring, it is essential to maintain good tree health. This includes regular fertilization, proper watering, and ensuring adequate air circulation around the trees.
