Tap time varies by location. Tap trees based on observations of when test holes begin running at a substantial rate (>1 drop per second).

Only healthy trees sized 8 inches dbh (diameter at breast height) or larger. A healthy tree shows no fire damage, no dead tops, and no visual evidence of excessive fungi.

Do not tap trees that have had pesticides or chemicals sprayed on or around.

Only one tap/spout per tree per year. Space subsequent year’s spouts around the circumference of the tree in a spiral pattern 24 to 48 inches high.

Sterilize the tap before use.

Use new plastic or nylon spouts commercially available or commercial stainless spouts if the spouts are to be reused.

Remove spouts immediately following the conclusion of sap collection for the season. Do not plug the hole.

Drilled holes may be only 1.5 to 1.75 inches deep and should angle slightly upward (approximately 10 degrees) using a 5/16 inch tapping bit.

Spouts should be tapped gently into place to avoid splitting the wood.

Motorized transportation (ATVs, snowmachines) to the harvest area may be used if allowed and it does not compromise ground cover or damage trails.
