Fruit and Citrus • Diseases
Unfortunately, we do not have a product in our range to treat leaf spot on blueberry plants.
To reduce fungal disease we recommend:
- Avoid overhead watering
- Water in the morning
- Improve drainage
- Improve ventilation by pruning or thinning foliage/branches
- remove mulch at the base of the plant to allow water to evaporate
- Well fed plants are less likely to be attacked by pests and diseases
- Improve availability of light
Physically remove and dispose of the damaged leaves on the plant to reduce the infection spreading to the rest of the plant.
