You should not plug trees after tapping. Tapping is the process of extracting sap from a tree, typically for making maple syrup. When a tap is inserted into a tree, it creates a small hole through which the sap can flow out.
After the tapping process is complete, it is important to let the tree heal itself naturally. The tap hole will gradually close up on its own, and the tree will work to repair any damage caused by the tapping process. This healing process is essential for the overall health and well-being of the tree.
If you were to plug the tap hole, it would prevent the tree from healing properly. The sap that is still inside the tree needs to be able to flow out through the tap hole, and plugging it would disrupt this process. It could potentially cause damage to the tree and hinder its ability to heal.
It is worth noting that after tapping, some sap may continue to drip from the tree even after the tap hole has been sealed. This is a normal part of the healing process, and it does not indicate any problem with the tree. The sap dripping is simply the excess sap that was already in the tree and is now being expelled as the tree works to heal itself.
In my personal experience, I have tapped maple trees for syrup production, and I have always allowed the tap holes to heal naturally. The trees have shown no signs of distress or negative effects from the tapping process. It is important to give the tree time to recover and allow its natural healing mechanisms to take place.
To summarize, it is not recommended to plug trees after tapping. The tap hole will naturally heal itself, and plugging it can disrupt the healing process. Some sap may continue to drip from the tree as it works to heal, which is normal and should not be a cause for concern.
