Last year my maple tree started losing leaves. I investigated and found it full of earwigs under the bark. I killed the bugs. The bark is falling off, Can I save my tree? It is over 20 years old.

Earwigs are not the damaging agent in this instance. Disease, winter, or physical damage may have caused the inner bark to deteriorate. This is where a plants water and food pipelines exist. Thus, the losing of leaves during the past season was an indicator of troubles. If the damage is not severe the edges of the area in question will begin to swell and seal over this spot. If this is occurring your job will simply be patience.

- I am an architect, working with a client who wants to hydroseed a 2.5 acre parcel for use as a softball field. The area is currently planted in alfalfa. There will be some regrading (both cut and fill) of the field that will be required. The client would still like to hydroseed this year, likely near the end of September. Do we need to call for the alfalfa to be treated with a herbicide? If so, what is the process, and what herbicide should be used? Is there a waiting period between application of the herbicide and the hydroseeding? Must the herbicide be applied to the above-grade plants, or can the site first be cleared, then the herbicide applied to the gound and roots?
