I don't think so?

A well-known consulting arborist I know told me the ISA says you can spike euc's if you go up 30 ft before doing so. I told him I doubt it and was going to bet my pay check, but he had such conviction it was true I chickened out.

Even if that was so.. It seems back asswards.

 

[Wayne Wilkinson]

What he ment was if he cant see it from the ground, and no one who had been in the tree says anything about it who was to know???

 

[JRoland]

Never heard of that. I'm thinking like Wayne says above, if you can't see it from the ground, didn't happen?
From a tree health standpoint, it almost seems the other way around would be better, spike up to 30 ft ( where the bark is thicker ) but I'm pretty sure that's not an ISA thing.

 

[derwoodii]

yup seems a mix up and then wrong any ways,, sure some euc are super thick bark likely nil harm but why if your skilled & geared up wont need to

Mos trees if I wanted to spike up I'd want to lower them after getting up to the branches. So if it was 'allowed' why would you?

 

[treesmith]

Australian and British standards for amenity tree pruning says no spikes

I'm sure the guy got it backwards.. As well as being mistaken. I'm sure I could hook the first 30' of a mature elm in these parts with pole gaffs, and never get through the furrows. But it would look like hammered ****.. And as mentioned before.. Why do you even NEED to at this point in the game?
