Green Giant Abrovitae have yellow branches with black tips

Hi- we planted a few Green giants in our backyard in June-July of this year. They seemed to be doing pretty well until now . I see some of the leaves yellowing and some have some weird black tips too.
Our trees are planted in area that's lower ground and natural slope of the backyard results in lot of water to these trees during rains.
What needs to be done for this issue? is yellowing natural in fall in new jersey ?
Thanks for your response in advance!

Blue Spruce White Needles

I’m looking for advice on a dwarf blue spruce we planted in March. It’s now late September and I noticed some off white needles. Is this normal? I love my tree and am a little worried. I’m also not sure what type of blue spruce this is.

We water it twice a week with a garden hose. Any advice would be greatly appreciated.

Service berry tree is falling over

My service berry tree is about 14 years old and 12 feet tall. It's staked but is falling over to the east side. Prevailing winds come from the west.
Is it possible to straightened this tree so it doesn't fall over? How and who can we call? It was originally planted by a nursery. They won't straighten it.

Poison Sumac or hickory?

Hi! I was walking my dog today and he walked through this shrub that grows on my lawn. we do not live near any marsh, bog, or swamp and this plant has been here for some time. I’m not sure if it is poison sumac or if it is some sort of hickory tree, such as the bitternut. I would really appreciate any help you’d be able to provide. I need to know whether or not I should bathe my dog and prep for a terrible rash or calmly watch a new tree grow.

Stuff on jade plant leaves

Hello! I noticed white/grey clusters of "stuff" on the leaves of my jade plant that weren't there before. I wiped the leaves off with a damp cloth, and found that the marks didn't go away, but revealed dark grey/black underneath. I'm worried this will harm/kill the plant. Is this cause for concern? What should I do? Do you know what is wrong?
