Crown rot
Caused by waterlogged soil or planting too deep; ensure crown sits at soil level and drainage is excellent.
Vine weevil
Larvae eat roots; look for wilting plants with damaged root systems. Use nematode biological controls or vine-weevil compost drenches.
Powdery mildew
Can appear in humid, still conditions; improve air circulation and avoid wetting leaves when watering.
Leaf scorch
Yellow-brown leaf edges from too much direct sun; move to a shadier spot or add afternoon shade.
