Good points, trees transpiration starts to slow down in the afternoon we usually try and stop around 230 pm, also sunnier days the trees will pull it up better then cloudier days. We use ima jet up here in the great white north no tree Age ( not approved yet)Oh yeah...time of day and soil moisture.
Make sure there's soil moisture the day before and get there in the morning, not afternoon. Translocation slows or shuts down and injection becomes near impossible, especially with Tree Age.
Did you pause at some point, and I missed it?Resorted to drinking beer.
