Adelgids on hemlock trees

We have an infestation of adelgids on 10 mature hemlock trees in our yard. We used dinotefuran granules 4 years ago and have been free of adelgids since then. I am wondering why the Ag Dept is now recommending Imidacloprid and not dinotefuran. What is your recommendation of a granular product?

Possibly excess chemicals applied to lawns?

Firms such as Tru-Green spray-apply chemicals to lawns, then post small signs warning nearby residents about possible danger to pets. Too, such applications are eventually washed away and carried to streams and other water bodies, causing problems downstream. It seems such applications are excessive and dangerous. What are your suggestions about how to tend to lawns without excess chemical applications? Thanks for your input

Aggressive, native groundcover that deer do not like

I am looking for an aggressive groundcover to outcompete an invasive houtynnia (chameleon plant) in an area of my yard. I cannot afford to dig up the entire area, and have found repeated applications of Roundup as was previously suggested by your office to be ineffective. I want a native plant, that is very deer resistant. Would ostrich ferns or equisetum fit the requirement? The area is a dry, sunny area, that will have limited access to hand watering. Thanks for any help. Sandy Laden

Japanese Maple

A Japanese Maple at my Rockville home has lacked vigor coming through the last few winters. Some branches are completely defoliated. Should I try to trim it or start over? I am attaching photos. Thanks for your consideration of this question.
