What is wrong with these two serviceberry bushes? At first it looked like lichen on the trunks, but now it is this black and I see flies and ants. We had a magnolia tree with magnolia scab that we took out in July. Could that have something to do with this? What should we do?

Theres these things on my oak tree leaf.

Greetings! We have two lovely oaks, a white and a red, which are in need of a trim but I don't want some local just hacking away at limbs. I really want to preserve their already long-lived life for our nine year old son. Is there anyone that you would recommend or would you be willing to send your students out on a field trip to learn how to properly trim-to-preserve? (Dunno if that's even a thing.)

Why are my Red Bell Peppers not turning Red yet?

Found this beetle dead outside on my deck and was wondering what it was. The gift card is there for size reference, it's about 3/4 inch. Thank you guys so much for your help!
