Jul 19, As soils dry out lack of water causes edges and tips of blueberry leaves to dry out and turn brown. This symptom is often confused with burn from a pesticide spray. The two drought stressed blueberry bushes show symptoms next to a less stressed bush. The healthy looking bush had shriveled fruit. Once most of the available soil water has been depleted, wholesale death of the leaves followed Estimated Reading Time: 2 mins. Leaves are yellow: Yellowing is interveinal, not associated with browning.
Interveinal yellowing is caused by iron deficiency, but is symptomatic of high soil pH. A high soil pH (>) results in the inability of the blueberry plant to use iron, causing a lack of chlorophyll production. Iron deficiency symptoms develop first in young leaves.
If the leaves are fine and it's just aborting flowers it's not either. The bud that is shriveled up is after the flower has fallen off. Instead of developing into a healthy blueberry, it just dries up.
