Reasons For Blueberry Leaves Turning Purple
Phosphorus Deficiency
A lack of phosphorus is a common cause of blueberry leaves turning purple. When there is insufficient phosphorus in the soil, it hinders the growth and development of the plant.
Too Much Nitrogen
Blueberries require a balance of both nitrogen and phosphorus to maintain healthy foliage, but if there is too much nitrogen available in the soil, this can cause the leaves to turn purple. The excess nitrogen stimulates chlorophyll production, which gives the leaf its purple color.
Low Temperatures
Blueberry leaves can turn purple due to low temperatures as well. When temperatures are too cold, it can inhibit photosynthesis or slow down its process, resulting in a decrease of sugar and energy levels for the plant. [1]
Over Watering
Blueberry leaves may turn purple when the soil is excessively wet or waterlogged. Overwatering soil can reduce oxygen availability and hinder the uptake of nutrients by plants, leading to discoloration and stress.
Magnesium Deficiency
Purple leaves in blueberries can also be caused by a lack of magnesium. Magnesium helps to regulate the movement of water and nutrients within the plant, so when there is not enough available, the leaves may start to turn purple.
Fungal Diseases
Blueberry leaves can turn purple due to fungal diseases. These diseases, such as anthracnose and botrytis, can weaken the plant and lead to discoloration of the foliage.
How Do You Fix Red Leaves On Blueberries?
