Proper Wound Treatment

[Tieball]

Ok here you go....
It's Acer ginnala, defoliated about 1 month ago. 18 (?) months after that bare root pic above.
It's nothing much without leaves yet. That will take another 8 years I reckon.
The wood inside was cleaned out as much as possible without the tree falling to bits, and then ''sealed'' with cut paste (out of the tube) The rot was completely natural as a result of die back after heavy pruning. I just basically removed the soft rot.

I guess the outsides will soldier on and cover well. The insides because of light restrictions will find it harder. You treated the areas with copper sulphate and calcium hydroxide as you mentioned above? What does the mixture do? What ratio?

No I didn't need to treat it because I was able to remove 100% of the rot. You can use 50/50 ratio or 70% copper. The calcium is to make it alkaline so the copper is less available/toxic. I don't know whether the wood is able to absorb much copper anyway?
