Stupid arborist

I set my climbing line by a homeowner's grill on the patio while dragging brush through the yard. At 10 am, that's a pretty safe bet. Until the cleaning lady comes outside while you're working somewhere else in the yard and starts spraying grill cleaner liberally all over your fairly new rope.

What happened to the cleaning lady? :rayos:

I was working on the ground and we were doing a complex rigging set up. It started to rain so I moved three Hanks of 1/2 lowering lines under the eves of the house. Pest control company comes by and does a walk through with the HO, didn’t think of it. Bit later when I’m receiving zipped limbs I see movement from the corner of my eye.! Same pest guy is spraying the perimeter of the house and goes right over all the ropes!!

Headed out to wrap some trees and shrubs for the winter years ago. Burlap and box of twine in the bed of the mason dump. Hopped on the highway. Apparently the wind was strong enough to suck the end of the twine out of the box, and just like Mac's, once there is a length trailing, it just keeps sucking more and more out. I finally glance in the side mirror and realize I'm trailing a LOT of twine behind me! Pulled over to the shoulder. Now it wasn't a new box when I started and it wasn't empty when I finally pulled over, but it's safe to say I was trailing several thousand feet of twine down the highway. Cut it off and put the box in the cab after that!
 
Ugh, I hate wrapping trees for SW disease. Can't do it with gloves on either.

Once sprayed some arbs with fertilizer and soil injected them with miticide.

They didn't like that.
 
Just what its called. Sun scald may be a more appropriate name.

Sites are great spots for decay fungi and flathead apple tree borer too.
 
For clarity, can you explain the mechanism of injury from warming/ thing-cooling/ freezing of the trunk, worst on the SW exposure, where the sun shines in the warmer part of the day?

In animals, frostbite, as I understand it, it is rupturing of cells as cell fluid freezes and expands. Is it similar/ same?

Where do you see it most?

Aka sun scald? How is it differentiated from sun burn for diagnosis and prognosis?


I wonder if sun burn is oriented at any different angle, like due South, where summer sun is most intense.
 
Basically it tricks the cambium into waking up and growing and a drop in temp (apparently it can be sudden such as when the sun is occluded by clouds) kills that area, perhaps as water expands and ruptures cells as you mentioned. Generally occurs on the south side of the tree, especially on recent transplants. Many maples are commonly afflicted but occurs on many plants here. Drought is also said to predispose trees as they head into the winter. More of a problem in the northern states.

Is there a big difference between it and sun burn? Perhaps the same thing but sun burn is generally attributed to tissues suddenly being exposed to more intense sunlight, such as when a tree is over-pruned and can occur anytime of the year. Makes me wonder about recent transplants that were oriented one way in the nursery and then planted in another. Perhaps a factor I would think.

Reactions: evo
Caused by intracellular/inside water going out of the cells and becoming extracellular/outside water. When the temp drops suddenly the water can't be ansorbed backninto
The cell quick enough. Water freezes and the ice breaks the cell walls

There is an antifreeze inside the cells and the cell walls expand somewhat

It's an amazing thing
 
Some cacti are marked for sun-orientation so they can be transplanted facing the same way.


Maybe better/ high-end nursery stock of trees, too????

If not maybe they need to be.




I've seen trees where I've wondered if adjacent land clearing for a house caused sun burn or SW Disease due to new sun exposure, or if it was mechanical damage that had been partially grown over.


Is sunburn or SW damage part of the reason people painted some trunks white?
