Scorched Leaves on blueberry
What's Happening
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.
How to Fix It
- 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.
- 3
Apply a thick 2-inch layer of pine bark mulch to cool the soil surface and retain moisture.
How to Prevent It
Use light-colored, thick-walled resin or wood planters rather than black plastic nursery pots for permanent placement.
