I have a young (~3 year old) brown turkey fig. I planted it last fall and it survived! the winter. It is producing small figs now but the leaves have a brownish gray powdery looking substance on them. It doesn't rub off but looks like powdery spots. Any clue what it might be or what I should do? The leaves remain green and look healthy. This appeared after the recent heavy rains.

It sounds like your fig tree may have powdery mildew. This is a fungal disease that occurs when weather conditions are both wet and warm. Below I have included a link about powdery mildew that includes more information about prevention as well as treatment options and recommendations.

- I have an older crab apple tree that is focal point of my small yard. About 3 years ago the leaves became infected with powdery mildew. I have been told to not do anything with this, as it will eventually go away and the tree will fine - but over the years it has gotten much worse each spring. There are only about 60% of the leaves that are starting to look healthy by mid-June. Over all, the leaves are withered and this year we have very few blossoms. Another problem: The tree also has four large limbs that come out of the trunk. I noticed that there seemed to be wood pulp inside a place where a branch was cut off years ago. I scooped out the pulp and found that some bug or other creature has created a cavity that goes 6” into the 10-12” diameter limb and a large man’s fist could easily fit into the hole that has been created. While inspecting the hole I discovered a ¼” or so hole in the very back of the cavity, but no sign of the culprit. The limb seems to be doing fine, as the leaves on the branches from this limb are in no better or worse shape than the rest of the tree. I had my tree pruned by a highly recommended person this spring, in hopes that this would help with my powdery mildew problem. I love my tree, what should I do next about my perpetual powdery mildew problem and the unknown culprit who is dinning on my tree limb?
