The Q&A Archives: Black Spots on Ficus

Question: My Ficus Melany is generally healthy, but one of the big leaves has developed a black spot along its edge. Any thoughts on what could be causing this and how to solve the problem?<br><br>

Answer: I'm not familiar with this particular cultivar of Ficus, but in general there are a few possibilities. A common problem with Ficus is scale. Scale insects look like small, oval bumps. They secrete a sweet substance called honeydew, which then attracts something called sooty mold, which is a black powdery substance. If you can wipe the black away, this is likely the problem.<br><br>If you can't wipe the spot away, my next guess is chill damage. Houseplant ficus are tropical plants and cannot withstand freezing temperatures. If the plant is near a door where it could get cold drafts, this could be the problem. Also, overwatering can cause leaf margins to turn brown/black.<br><br>Finally, have you sprayed anything unusual on the plant--either a pesticide or cleaner? These tend to collect on leaf margins and may have been a factor.<br><br>I hope this helps you figure out the problem.
