Q.Silver Birch

Anonymous added on March 7, 2014 | Answered

I have recently taken some overhanging branches off a mature (30 year old) birch tree. The “wound” continues to bleed. I have, as recommended, used a blow torch to seal them and have liberally coated the cuts with Arbrex sealant. All to no avail. Will the sap eventually stop dripping or is there some way to seal the cuts?

I would actually not recommend using any sealer at all. It can trap bacteria and disease against wounds, which can harm the tree. The wounds will seal and heal well in the open air. The sap is rising and is common for this time of year and the tree should be fine, eventually healing itself.
