Broken branch
I have a problem with a 6-meter (20 ft) pine tree. Last winter, the snow broke a large branch in the middle. We tried to secure it with supports, but it remained brown all summer and never turned green again. Do you think we should cut it down, or is there a chance it will recover next spring?
Answer
If the branch has shown no signs of recovery throughout the summer, it is dead. You can therefore cut it off. (Note that there is no specific season for removing a dead branch. You can remove it at any time!)

Linden tree in poor condition
I have a linden tree that is about 35 years old. It has always grown well, but this year, half of its branches have far fewer leaves. What is happening to my tree? Note that two weeks ago, I applied a potassium-rich tree fertilizer around its perimeter.
Answer
It’s impossible for me to say what’s wrong. The possibilities range from disease to insect infestation, damage to the roots caused by construction work, or even a lightning strike! Examine the weak branches to see if you can find anything unusual, or better yet, have a certified arborist take a look.
Be careful with fertilizer applications, however: you should not fertilize a diseased plant, as it may not be able to absorb it, and excess minerals at its base can damage its roots. Only fertilize healthy plants. In other words, don’t use fertilizer as a remedy, but rather as a reward.
