Chalky dirt

Hello - When digging holes for planting in some parts of my yard (1/3 acre lot in SW Portland) I've been finding soil that is very chalky-looking. Seems like it's a "new" phenomenon that I've seen only in the last couple of years and it appears more prevalent in the areas of the yard that have the most clay (but I'm not 100% sure about this). Is this mold? Will improving the soil with amendments help? Is it safe to plant in these areas?

Replanting a smoke bush

Being home so much I noticed there is a house-created shadow over the smoke bush planted two years ago. It does not seem to be thriving in any case. I am willing to risk transplanting it to see how it does in a spot with more light. It is about 3 ft tall. How far out and down should it be dug out?

What is this?

We have an abundance of this low growing ground cover in the back section of our yard. It’s only one to two inches high at most, and grows in shady areas (under our Doug Fir stand). What is it? Thanks so much!!!!

What type of grass is this?

Hello! I could really use expert help with this. Two years ago I put in “oregon tall fescue” sod in an area that is difficult to grow grass. Sandy loam is the soil base. (Difficult because it is pretty shady, is a low point, so has constantly wet soil and is under some Doug Fir trees) Sure enough, it’s not doing very well after the second winter but another species seems to be patching in quite nicely (see photo’s). I would like to find out what grass this is so I can seed with it. Can you help me? Thank you so much! -Eric Lake Oswego, OR

box wood disease or pest

Hello,
I went to prune my hedge and noted it was dying back in a couple spots and Many of the leaves had yellow spots on top of leaves.
When I shake the plant , lots of white particles fly in the air.
I don't see any caterpillars. There are lots of clusters on top of leaves of what look like tiny eggs. Backs of leaves look ok. I don' know what it is or how to treat.

Holes in lawn

I have a lot of 2-3" wide holes in my lawn that I suspect is from mice or vole activity since we live in an orchard area. What's a good way to get rid of them? Thanks, Paul.

Dying Southern Magnolia ( Magnolia Grandiflora) Tree

I have a 15-20 year old Magnolia tree, about 30 feet tall, and that has been extremely healthy until this year. Attached are several pictures. I believe it is a Southern Magnolia ( Magnolia Grandiflora) and is in full sun. There are no competing plants near it and nothing has been disturbed in its root system. Thank you for any advice you may have, as I really don't want to lose this tree. There is also another identical tree in another part of our yard that is doing very well...
