I cut off a large branch a couple years ago because it had partially broken off and noticed there was a soft spot in that area. This weekend, I dug out all the soft wood including pulling out a dozen big white worms. The tree is still in great condition, but I’m wondering what I can put in that hole so more wood doesn’t rot out with the rain that’ll collect. I know it’s dumb and tacky but would spray foam work?

When you cut off the branch you should have treated the stub there and then.

They make sealers specifically for sealing the remains of cut off limbs that help prevent moisture uptake and insect invasion.

You should probably talk to an arborist to see what they recommend since you now have some sort of borers in the tree doing their damage.

Yikes, that’s not what I wanted to hear.

Nasty damn trees that I would not have on my property. Thick arse waxy leaves that don't decompose easily, nasty red seeds when the cones go to seed and those damn cones as big as grenades falling off the tree after the flowers die out.

Nothing but a huge mess to maintain. When I was a kid the neighbor had 2 HUGE magnolias right on the property line and I probably raked up hundreds of garbage bags of leaves before I left home at 17 to find my way in the world.

Yes….as someone else said, there is a product called pruning sealer to spray on freshly cut limbs to keep that from happening.

If the tree has already got a chunk rotten out, I have repaired that by cleaning out until you find fresh wood and then filling with quickcrete. If the hole is basically vertical, you can nail a piece of plywood to partially cover the hole to make a form that will hold the concrete.
