Evergreen tree stress

I assume trees dropping lots of green needles due to stress, can recover?

Specifically spruce seedlings 16-20 inches tall?

I can rub my hands over the branches and bunches of green needles come off.


Thanks

Ummmmmmm.................... green needle drop............not good.

All the conifers have an annual needle drop. But it is of dead, inner needles that are brown. Losing green needles this time of year is not normal at all.

Are there green needles laying on the snow under the trees ?? Or do you have to rub them to get them to come off ??

Have to rub the branches to get them fall off but they come off easy.

The other trees do not lose any needles. I have about 8 trees in this area.

Is it just these younger ones or are mature spruces in the area doing the same?

Definitely not good.

What part of PA are you?

That's a pretty good article that briefly touches on needlecast. Spruces, mainly blues that I've noticed, have been in major decline here in southern butler county for the past 5+ years and the effects are really starting to be noticeable if you look. It's a slow death and the tree services are going to be busy!

No older trees.

These are red spruce trees about 2-3 years old and they are growing in a transplant outside bed I have in NC.

2 of the 8 trees have this problem. The other 6 seem to be fine for now.

I was going to let them get bigger and then plant them in PA. I had already planted some spruce in PA and only a few made it.

I figured bigger trees would do much better.

Not so much so.

Generally the trees that will do best are smaller trees with bigger root structures. 2 to 4 year transplants will cost more. But will usually do better.

A transplant tree will be listed in the catalog like "Colorado Blue Spruce 3-2" That translates to a 5 year old tree which spent 3 years in its sown seed bed, was transplanted into a roomier bed, then spent 2 years there before being dug to sell. A 3-2 tree will have a smaller top than a 5 year seedling. But it will have a MUCH more massive root structure. Much better for a tree, stressed by planting, to have a lot of roots attempting to nourish a smaller top than to have smaller roots attempting to nourish a bigger top.

These are red spruce plug seedlings grown for restoration purposes in the mountains.

I should try and take a picture.

I'm trying red spruce to see if they grow as well in western PA as norway spruce for habitat purposes.

My plan to create evergreen patches in the understory open deciduous woods. Red spruce are very shade tolerant.

Plant hundreds of 3-0 Norway spruce seedlings. Well planted seedlings that had been properly cared for prior to planting will yield blocks of cover if planted in 15-20 tree irregular shaped clumps. And they're cheap.
