scorched leaves on Blueberry
Quick answer
If your Blueberry has scorched leaves, the most likely cause is: Container blueberries placed on concrete balconies or patios suffer from high radiant heat. Dark-colored pots absorb sun, cooking the shallow roots, leading to crispy brown leaf margins and dropped fruit.
Start here:
- 1. Move the container to a spot that receives morning sun and afternoon shade.
- 2. Place the container inside a larger, light-colored pot (double-potting) to insulate the root zone from direct sun.
