How hot is too hot for egg sacs
I bought my praying mantis egg sack from my local Fred Meyers. It's been over 90 degrees outside last few days, and it's been hanging out in that temperature on the fence without any shade. Do I have any concern for my praying mantises? I bought the praying mantises 2 3, weeks ago back then it was high 80s.

Bark peeling away on Japanese cherry (Amanogawa)
Last summer (2018) was hot for very many weeks and sap started to come out on the west side of my Amanogawa - this attracted ants, who began to gnaw on the bark (I saw bark dust on the ground). Once I got rid of the ants and temperatures cooled down, the tree bark didn't look too bad - see the photo. Over the winter and now into spring (2019), I had hoped the bark would heal, but it seems to be splitting open and getting worse - see the next two photos. I have seen no insect activity and there has not been any damage by tools, etc. The last two photos perhaps look worse than they really are because the tree was wet from rain today. I can provide more photos if permitted. The leaves are nice and green and the branches look fine. Help! I do not want to lose this beautiful tree.

Arborvitae helpless or hopeful?
Quite a few of my arborvitae have died or are half dead? Half brown or partially black on the inside. Should I just cut back all the brown black limbs and hope for the best? Fungicide? Toss them? Help me !!

Hello - my daughter lives in Walla Walla and they have two of these trees. She'd like to know what they are, and if the fruits are edible or useful in some other way. Thanks very much.
