What Is Causing My Blueberry Bush’S Leaves To Turn Brown?

An overwatered or underwatered blueberry bush will turn brown if the plant is either overwatered or underwatered. There are some cases in which the leaves of a blueberry bush might turn brown if the pH of the soil is not balanced properly. For blueberries, the pH level should be between 4.5 and 5.5.

The absence of water in the soil causes the margins and tips of blueberry leaves to dry up and become brown when the soil dries out. This symptom is frequently mistaken for the burn caused by a pesticide spray.

If you notice brown spots on your blueberry leaves, it is likely that your plant has contracted one of the several Blueberry leaf spot illnesses. It is most typically the case that these dark patches are the consequence of a fungal infection.

What’s wrong with my blueberry bushes?

A lack of sunlight or excessive exposure to the sun can increase the risk of developing health problems.Similarly, blueberries require soil that stays regularly wet while still being well-drained.Watering the plant too much causes shallow blueberry roots to become clogged, resulting in nutritional imbalances and the plant becoming weak and sickly.

Epsom salt might provide brief comfort if your blueberries are deficient in magnesium. In soils that are poor in magnesium, sprinkle 1/4 cup Epsom salt around the plant in a 10-inch circle and thoroughly water it.
