Tree tap from Maples in spring worked fine, but when trying it at fall on Pine Trees it failed.
First time i tryed it in fall it consumed the tree tap, but gave me nothing back. I did it on 20 trees. I tryed clicking in the next days, to see if maybe the Pine Tree Sap used longer time. But nothing happened when clicking the trees.
After a week or so I tryed to use new tree tap on the same trees.
This is the message showing (same as i get in spring when trying to use it on a tree that have allready given me Maple Sap)
