I have a river birch in my backyard I planted 6-7 years ago. It is doing really well!
Last summer in July we went on a one week holiday and upon returning every leaf on
the tree was gone! Small green caterpillar with brown spots had attacked. I have never
seen anything like that before or since. The tree is probably 16 feet tall so I don't
know how I would spray it. Any thoughts on how I might control this infestation occurring
Let’s hope it was a one season problem. Monitor the tree this season and if you spot
a problem, take a sample to your county extension office for diagnosis. There are
numerous insecticides that kill caterpillars, but they are typically applied as needed,
not as a preventative spray.
We have a new home and just planted a small river birch sapling, it seems to be doing
very well. There are several small shoots coming up around the trunk (which is only
about 3 inches around, should we cut these shoots to allow the main trunk to grow,
if so when is a good time, and can we replant the shoots?
River birch trees can be single-trunked or multi-trunked. If yours is a single trunk
form, cut off the suckers or they will begin to compete with the main tree. If they
have roots attached--which most suckers don't, you can replant this fall. Usually
it is just best to cut them off slightly below the soil line as you see them.
