How to Treat a Fig Tree With Brown Leaves

Figs trees have a good resistance to pests and diseases. Even the best fig tree can succumb to problems. In most cases, these problems may be caused by lack of maintenance around the plant. If the fig tree does show signs of yellow to brown leaves, the problem may be twofold. While basic sanitation will create a clean area around the tree, the fungus causing the brown leaves still must be eradicated. In most cases, a fungicidal application of 4-4-50 Bordeaux fungicide spray over the course of the summer will solve the problem.

Inspect the fig tree to ensure no insects are causing the problem. Look over the tree trunk and on the underside of the affected leaves. If no insect egg casings are found, chances are the fig has a fungus problem.

Remove all fig leaves from below and around the tree with the leaf rake. Move the leaves to an area far way from all fig trees. If possible, burn the leavers or place them in the trash to be removed from the property. Do not use the leaves in a compost pile. The fungus may lie dormant and be transferred at a later date.

Mix the 4-4-50 Bordeaux fungicide spray according to the manufacturer's instructions inside the sprayer. If you wish to make your own spray concentrate, see the Resource section below.

Cover as much of the foliage on the fig tree as possible with the spray solution.

Apply another spray coating every three to four weeks during the summer.

Keep all leaves raked up from around the infected tree. Dispose of the leaves in the fashion as described in Step 2 above.

Fig Tree Leaves To Wilt?

Fig trees are typically hardy in U.S. Department of Agriculture plant hardiness zones 8 through 10, though some cultivars grow in cooler climates. Because the roots of fig trees grow close to the soil surface, they are prone to drying out. Although it is important to keep the soil moist, too much water in poorly drained soil can also lead to wilt and fruit drop. Fig rust is a fungal disease affecting the leaves of fig trees. Other insects belonging to the genera Epitrix and Colaspis feed on the leaves and shoots of fig trees, perforating the leaves and leaving them susceptible to wilt and further damage.
