Guava trees are relatively low-maintenance, but a few common pests and diseases can affect their health and fruit production. Here's what to watch for.
Fruit Flies
Fruit flies are one of the most common guava pests, laying eggs in ripening fruit and causing internal damage.
Scale Insects
Small, immobile scale insects can weaken a guava tree over time by feeding on sap from stems and leaves.
Anthracnose
This fungal disease causes dark, sunken spots on fruit and is more common during Florida's humid, rainy season.
Root Rot
Poor drainage can lead to root rot in guava trees; well-draining soil is key to preventing this issue.
