I had to remove a dead limb off of my 50+yr old gravenstein tree and I'm wondering how I should treat the exposed wood. Concrete? spry foam? Any ideas please?
You could try biodynamic tree paste, latex paint or nothing.
Thanks John. I’m ok with leaving it as is with the exception of the hole exposing the internal cavity. I’m concerned it might be a problem later as it accumulates debris and water. What would be a good material to fill it with? If it needs it at all....
In hardware stores in electrical section you can locate the sealant product on the lowest shelf that are usually among wire spin-tight connectors. The electrical version is not green like the horticulture stores sell but it is exactly the same thing for less than half the cost. We electricians use it to keep up the integrity of wires poking through moisture barriers from inside to outside wiring etc; which also keep harmful bugs like termites completely outside. I keep this stuff around for grafting as well.
Thanks Rooney. Can I use it to plug the hole in the exposed wood as seen in my picture from my original post?
