| We have land outside town with tons of aspens. In our campground we have an Aspen grove with sick aspens. They only get to about 20-25 feet tall and then die. They almost all are infested with poplar borer and many have aspen trunk rot. My guess is that there is nothing I can do to help these trees but I thought I'd ask anyways. I have to cut down several trees every year because they die so often. |

| All you can do is try to reduce stress if possible. You could also clearcut the stand to rejuvenate it. Poplar borer and trunk rot indicate the site isn't ideal for their growth and they are stressed..by drought maybe? |

| I would think you could use a systemic insecticide like imadicloprid to treat the borers. Don't know if that would be economically feasible, furthermore, I don't know if that would be "technically legal" -- probably Aspen, being mostly a "weed" tree in most eyes, wouldn't be the type of crop that a company like Bayer would waste money testing on so they could include in the label, but who knows? If the trees are already in bad shape, I agree with the above thought -- maybe cut them all down, so you can selectively allow regrowth, and then manage that to control the issues the old growth was facing. Aspen grows SO fast, you'll have a nice, new grove in just a few years if the conditions are conducive. I know my couple of trees put up suckers that can get to be 5-6 feet tall by the end of summer if I let them go. Personally, I'm a big fan of aspen, because its a very, very pretty tree IMHO, despite its drawbacks. |

| It could easily be due to drought. They grow on a ridge at the edge of a field. The trees in the valley are tall and healthy. I'm not sure I want to clearcut because I love these trees but even if I just cut the really sick ones down I would imagine that'd help? Water might help too. |

| In my region, aspen stands often serve as nurseries for spruce and fir. Are there equivalent conifers in your area that could be encouraged to start under these sickly trees? +oM |

| If you know what specific conditions are afflicting them - as you seem to - you can find recommendations for dealing with these conditions at the same places where such conditions are identified and described in general. Google their names, see what is said. |

| Thanks. There are a few young Douglas firs growing underneath as well as some trees I planted. I want some areas free of aspens eventually but want to keep them in other areas. |
