Sickly Dwarf Alberta Spruces (I think that's what they are)

9 years ago

I have 2 of these ornamental trees in containers in our back yard which is mostly shaded, and gets some morning light. The photo is the worst of the two trees.

Both trees have spots like this on the back of them, the other tree it's mostly on the back. This tree it's on the back & also on the front as in this picture. As you can see though, this tree also has some green in the top of it.

I'm trying to save both these trees, but don't know what is wrong with them. I had them sitting where they got indirect & mid-day sun, and moved them a couple months ago, but have not noticed a difference. They're watered regularly, and fertilized with evergreen fertilizer every couple months or so.

Would appreciate any advice or suggestions as to what I can do to save both of these - they weren't cheap & the last set I had in planters someone "borrowed" and forgot to water for a whole month.

It's time to replace them.

The fact you transplanted them in this condition didn't help matters any. It put them in more stress.

They will never regenerate new growth.

These conifers need full sun all around for balanced growth.

I checked today & see some type of mite in each of the plants. There are pretty large sections of the tree that are like the brown section, and other parts of the tree (on all sides) appear to be healthy.

I took several branches & shook them over a piece of white paper & could see some specks that moved. I looked under magnification & could see a little reddish creature that had a black spot at one end.

Assuming it is a mite, what is a good treatment for them that doesn't target beneficial insects & bees?

it is NOT WORTH SPENDING MONEY on a mitecide ...

as the plant is near death regardless ... the vertical part will NOT recover
