Curious as to what these guys are hanging around the library.

I saw these guys hanging out under some dusty shelves in a library. They varied in size but they all had the same color and shape?

Trimming my rose of sharon

I have a sugar tipped Rose of Sharon. The leaves are a lighter color of green and variegated. The bloom is a very light pink. I am wanting to trim it. Can I do that in the fall or should I wait until Spring? If trimming in the fall, should I wait until it stops blooming? I am hesitant to trim in the Spring because just when I feel it is warm enough to trim it, it has small buds ready for blooming.

Crate Myrtle diseased (possible fungus)

Hello there! Firstly, let me say how grateful I am for all that you do for our community. I noticed a few weeks ago that my crate myrtle (which I planted in spring of 2016) started developing some white spots/scales on the branches. Some of the leaves have browned (not many) and it looks like there is some kind of a resin on the leaves as well. The flowers are in bloom, but are obviously being affected by whatever is attacking the plant. I'm wondering if it's a fungus of some kind and if so how I can treat it. I would hate to lose the plant. I have attached photos I took. Please take a look and let me know your thoughts as well as if you need further information. Thank you so very much! Cheers, Lesley Shollmier

treatments by yard service

My yard service applies all kinds of chemicals to grass during year. I do not get all of their many services; but I do receive fertilizer, pre-emergent treatments and a few treatments that "sound good from yard personnel." My yard has patches where grass is dead, some of the patches have a white substance on top. Is there anything I can do to resurrect this grass? Lawn company says "fertilizer will green up grass," but grass is dead. Can fertilizer cause dead grass to come back? Thank you.
