The loud buzzing of all those cicadas has finally subsided, and you鈥檙e free to spend some quiet time in your backyard again. But instead of dodging dive-bombing bugs, now you have dying tree branches dangling and falling off.
First, before you overreact, you need to be sure it鈥檚 cicada damage.
鈥淵ou鈥檒l see like the little train track patterns on the side of the branches where the females actually laid their eggs,鈥� said Dave Kemon, holding up a little branch with dotted lines carved off in the bark.
Kemon is a floor supervisor at Homestead Gardens in Davidsonville, Maryland, and someone lots of people seek out for advice on things going wrong in their yards.
鈥淭hey鈥檒l be in that branch for about a little over a month and then the nymphs will hatch and fall to the ground and go into the ground and come back in 17 years,鈥� he said.
You have two really simple choices if that鈥檚 what your left with: leave the branches there to fall on their own or cut them off yourself.
鈥淚f they snap dead, just cut them,” Kemon said. “Normally only half of it will be dead, so just cut the bad part and a new shoot will come out from the other side, it鈥檒l re-germinate itself. Anything that will snap right off, if you鈥檙e worried about it, just get rid of it.”
He said the bugs seek out thinner, smaller branches to lay hundreds of eggs in each little “line” in the hopes that eventually the branch will die and then fall off, giving the nymphs an easy escape underground.
“If you notice a lot more branches dying, you have something else going on besides cicadas.
“It doesn鈥檛 hurt once it鈥檚 over and done with to give the plants some nutrients just to boost it back up again. Any type of plant food.”
Otherwise, don鈥檛 sweat it.
“Trees are kind of like us,” Kemon said. “We cut our finger, we automatically heal. Trees, if something scratches them or hits them or they snap off, they heal over, so they take care of themselves.”
