Tapping Birch Trees for Sap

[pinerevolver]

Hey Guys,
I live in the central of Scotland and im looking on tapping birch trees for there sap in the third week of March, recently in Scotland we've had a fair bit of snow here in late Febuarary. I wondering atol if that would have any effect on me tapping the birch trees would it hold the process later on ? :confused:

It may delay it, only thing you can do is keep checking.

There seems to be no rhyme or reason to when the sap starts up here. I just test every week or so until i see a good flow. I think it would be pretty tricky to tie it down to a specific date.

I wait until the first buds of leaves appear ;) - this proves the sap is on the way up to feed the tree.
