What i have done is this the silver birch i have been trying to collect from have been fairly young would this make any difference??
I have drilled into the tree about a foot up from the ground I went in approx 4 cm's deep connected my tube which is a tight fit and masked around the hole and tube with tape.
Can anyone please give me some advise as i left this over 2 nights only to find nothing

If anyone can give me advise or a location near to Maidstone down in Kent where they know sap is good that would be fantastic!
