An app can help you notice a problem. An extension worker or plant-health specialist can examine the whole tree and the garden.
Ask for help when
- Many trees are affected, or the problem is spreading quickly.
- Trees are wilting, branches are dying or bark is damaged.
- Berries or flowers are affected.
- A scan result was uncertain, or does not match what you see.
- You are thinking about buying any chemical treatment.
Your local government agricultural office or coffee cooperative can usually connect you with an extension worker.
