Anybody get winterburn on some of their trees?

[Nybonsai12]

Same here Sandy. Mugo's moving, scots looking to just get going, Any decent sized black or white pines I have aren't moving just yet. Smaller seedlings of black and red pines have just started moving.

All maples I have are also leafing out but not hardened. J. Quince have leaves and flower buds are starting to swell. C. Quince and Ume starting to show buds swelling.

Nothing too noticeable on the Junipers yet. I'll have to take a close look though as I haven't really inspected in the last few days.

My JBP are fine, they were further from the door and didnt freeze.

This is my scots, which is odd I know because they are very winter hardy normally. It isnt just the pine. The junipers that were next to it are also showing signs of winterburn. All were next to the door and all froze solid. The temps in that spot went down to 15 deg F for a few days.

Again they were watered except when they were frozen, then they were piled with snow to get the melt when they started to thaw. The soil was never bone dry on any of them so I cant believe it is lack of water except for when they were frozen.

I am thinking freeze thaw cycles, it can warm considerably in sheds and garages. Also by the doors they may have gotten the cold drafts after warming.
Do the look like a whitish color over most of the needles?

Everything is a very pale yellow, strawlike color. The color is uniform, no banding or spots.

Junipers: On the San Jose, the tips and half of the spring toward the branches are discolored. The inner areas are still green. On the Procumbens it is mostly the tips and some of the ends of the branches. Ive trimmed off much of the yellow to get more sun to the inner parts of the branches.

The pine: the tips of the needles extending half to 3/4 of the length of the needle to the center of the needle center (bud) are discolored and needles look dessicated in that area, like they were freeze dried. The part of the needles surrounding the buds and the buds are still green and most seem to be swelling a bit.

Signs of hope.

The buds are starting to shed their outer casing and you can see the tiny green proto-needles/candles and many are starting to elongate.
Been keeping it out in the sun, misting it 2x a day (3x on weekends) and putting it inside when the temps are below 40 deg F.
Still weak and has a long way to go. Hopefully it can hang on and push those new needles out.

Hopefully it can hang on and push those new needles out.

Update? My Yew, Junipers, and all the Larch are doing ok here. On a very dark note it looks like we lost all 10 nice Maples, all Hornbeams, all American Elms, all Mulberry, all Cotoneaster, all Crape, and more to something called pseudomonas. It is attributed to a damp period we had I will continue after the mass burning but DAMNNNNNNNNNNNNNNNNN

I'm on the same boat. A few of my largest trees are barely budding out..a couple only has a handful of leaves and my largest trident has really weak leaves. Another one haven't bud out yet so it's probably dead (it was weak last season which may have doomed it).

Like paradox, I thought I was diligent watering this winter so I'm not sure if I over or under watered. It couldn't have been too cold in my garage. I literally checked every single day and my garage insulates very well... warmer when it's really cold outside and cooler when it warms up outside.

I think we all need to winter our tees at Dav's house

I'm not sure if it's related but when we did major landscaping a few years ago we found we couldn't plant coniferous shrubs on the south side of the house because in late winter the sun would heat them up enough to make them start coming out of dormancy and then we would get a cold snap and all of the sun facing foliage would die

 

[Paradox]

Grim, I read the other thread about your diseased trees. I am very sorry to hear that and I feel your pain.

I am on Long Island.
The junipers are showing some buds at the bases of branches and branchlets and the few tips that didnt get damaged to so I think they will grow out of it.

The pine is losing alot of its one year old needles but the candles are all green and opening out into needles so it is also hanging in there. Like I said, hopefully it can hold on until those needles are fully out and can start photosynthesizing.

 

[Nybonsai12]

Glad to hear things are turning around and your trees are moving sandy.

My junipers are pushing new growth, mugo, red, white, black pines are making nice candles or are open with the exception of two. A white pine that had a bunch of dieback(buds are green just not extending)and a large black pine with no candle extension that is currently covered in tons of pollen cones that are making a mess.

 

[Paradox]

Yep Ive got most of my early repotting done already. All my pines have candles expanding out needles and almost all my juniper are budding. Last year I was repotting into June. The trees are in a hurry this year.

 

[M. Frary]

I've spoken too soon it seems. I lost 3 chinese elms I think. They are still flexible but nothing is moving. I also got some burn on my Bristlecone pine and this freaks me out some because if anything you would think it would be able to take some extreme temps. Japanese maple and Barberry are toast too. Kind of figured they would go. Especially the maple.
I lost some nice trees but learned a whole lot too. These things happen.

 

[Skinnygoomba]

We had cold this past winter that I cannot remember ever having experienced previously.

 

[M. Frary]

It got so cold I could cut glass with my nipples they were so hard!

 

[Paradox]

Sorry to hear about your trees Mike. I did have a couple die, but while dont like losing any tree, if I had to lose a couple, I would prefer those 2 than the other 3 that I dont want to lose. So far all 3 are still kicking.

 

[Paradox]

Out of the woods?
At this point, I think this tree is going to make it so I feel better about posting pics now. It is still going to be a long time before I can work on this tree again because it needs to grow.
I really wanted to repot it this year but I think that is going to have to wait for it to get strong again.

The needles are all pretty much expanded and almost hardened off. The centers of the needle clusters have little buds so the tree is really trying hard to live (you can see them in the last picture).
The first pic is without a flash just so you can see the real color instead of the yellow tint the light of flash gives off. You can see it has lost most of its 1+ year old needles. It did push out some new buds in different places though. I just hope I can get it to stay healthy and not get this problem again next year. I have been spraying it once a month with fungicide just in case that a fungus was part of the issue here which seems likely. Ive been alternating with copper fungicide and daconil.
