Fig Tree Pests & Diseases: Region Edition for Thrips, Mites, Anthracnose, and Root Rot
Fig trees are hardy and rewarding, but they are still vulnerable to pests and several types of fig tree leaf diseases throughout the growing season. Whether you're caring for a young tree or a mature one, learning how to recognize common fig leaf diseases and other forms of fig disease will help you prevent damage and protect your harvest.
The good news is that most issues can be caught early just by keeping a close eye on the leaves, fruit, and branches.
Understanding Fig Tree Pests and Diseases
When growing fig trees, it’s important to be aware that fig pests and diseases can affect the entire tree, from the roots to the leaves, branches, bark, and fruit. Problems caused by eriophyid mites or spider mites often appear as yellow spotting or leaf distortion, while fungal issues may lead to browning and, in severe cases—including common fig fruit diseases—reduced fruit production or premature fruit drop.
Organic methods are preferred for managing these issues, and although chemical control exists, it’s generally avoided in favor of sustainable, long term solutions that protect both the tree and the garden ecosystem.
Before diving into treatment, let’s explore the issues you’re most likely to face.
Common Fig Tree Diseases
1. Fig Rust Disease
One of the most common fig tree diseases, fig rust is a fungal disease that appears as small yellow spots on the fig leaves. These spots eventually turn brown and cause leaves to drop early.
Signs to look for:
- Yellow spotting beneath leaves
- Brown, rusty blotches
- Early leaf drop
Prevention & care:
Improve airflow, water early in the day, and remove infected leaves. More care tips can be found in this helpful guide to planting and caring for fig trees.
2. Fig Mosaic Disease (FMV)
Fig mosaic disease or fig mosaic virus FMV causes distorted, mottled leaves with patchy yellow spots. While not usually fatal, infected trees may show reduced vigor and smaller fruit.
What you’ll notice:
- Yellow mottling
- Distorted or curled leaves
- Slowed growth
Because FMV spreads through fig mites, pest control is important.
3. Fig Anthracnose
This fungal infection leads to leaf lesions, dark spots, and browning edges.
Symptoms include:
- Leaf spot patterns
- Brown sunken patches
- Affected leaves curling
4. Root Rot
Whether caused by poor drainage or overwatering, fig root rot is one of the most damaging fig plant diseases.
Fig tree root rot signs:
- Drooping leaves despite moist soil
- Black or mushy roots
- Yellowing before leaves fall
Fig tree root rot treatment:
- Improve drainage
- Repot if in containers
- Reduce watering
- Trim away damaged roots
5. Fig Tree Bark Diseases
Some diseases of fig trees affect the bark and branches, causing cracking, oozing, or dark lesions. These may be bacterial or fungal.
Watch for:
- Split bark
- Sticky ooze
- Branch dieback
If branches become infected, prune several inches below the damage.
Pests on Fig Trees
1. Fig Mites and Fig Blister Mites
These tiny fig mites are among the most persistent fig pests. They often cause blistering, rough patches, or curled leaves.
Signs of fig blister mites:
- Tiny bumps on undersides of leaves
- Yellow or bronze patches
- Deformed new growth
Mites are also known to spread FMV.
2. Root Knot Nematodes
These microscopic pests attack the root system, causing galls and stunted growth.
Watch for:
- Poor fruit production
- Wilting
- Knobby roots on rooted cuttings
3. Scale Insects
Scale insects appear as tiny brown bumps on leaves and branches and can weaken the tree by sucking sap.
To manage these persistent pests organically or chemically, you can explore effective options in our scale insect and bug treatment collection.
4. Beetles, Ants, and Birds
While not “traditional” fig pests, these creatures attack fig fruit directly, especially during peak fig season.
For gardeners managing multiple fruit trees, many fig pests behave similarly to orchard pests. Our guide to apple orchard pests and identification offers useful tips that can also help identify and control fig tree pests.
If wildlife is a problem, you may want to explore other deer-resistant vegetables and berries to plant nearby.
Fig Tree Pest Control & Disease Prevention
1. Improve Airflow and Sunlight
Good airflow reduces fungal disease. Prune lightly and space trees well.
2. Water the Right Way
Overwatering invites root rot, while wet leaves encourage fungal infections.
3. Choose Healthy Varieties
Buying healthy, disease-resistant trees gives you a strong start. Browse our high-quality varieties here: Fig Trees Collection
4. Follow Proper Planting Practices
Planting correctly helps prevent disease from day one. This video on planting a potted fruit tree is a great beginner resource.
5. Maintain Good Garden Hygiene
Remove affected leaves, dropped fruit, and debris to prevent reinfection.

Conclusion
Fig growers face a range of fig tree diseases and pests, but most issues—whether fungal, viral, or insect-related—can be managed with early detection and consistent care. Watch for early signs like yellow spotting, curling leaves, and damage on the bark or roots. With proper practices, your fig tree can remain productive and healthy throughout the growing season.
