There are fungi that can attack your fig tree leaves. If you find large brown areas, or with a mold growing – immediately cut off the affected leaves and discard them so that the fungus will not spread throughout. Take note that there is a very dangerous common leaf mold pathogen called Rust. It mainly affects potted plants and can spread to your house plants. It will begin with small brown spots and gradually spread through the leaf. When you discover this type of infection, cut the leaf off and burn it. Read more
Solutions are available for injured fig leaves. Fig trees in this area of the Northeast don’t have many pests. Once in a while, you’ll come across leaves being eaten or discolored. Sometimes you’ll find that nothing is eating the leaves or branches most probably because the sap (latex) is sticky and can be irritating (even to human skin). Other times, the problem might not be a pest, but a rust fungi infection. Read more
Yellow, wilting or curling leaves. This is a sign that your tree is dehydrated and needs water ASAP.
If the tree has been growing in the ground, place a garden hose directly at the base of the tree and let the water trickle over it for at least 1-2 hours. Watering a tree can be a daunting experience sometimes, so I bought this Drip Irrigation Water Rock. It might look ugly, but you can apply latex paint to it to change the color. In the meantime, it has a continuous water drip into the roots of the tree. If it’s a young freshly planted tree, continue to water it on a regular basis about once every 3 days (skipping on rainy days) until the growing season has ended.
