How to keep a pine tree alive

The bark is no big deal but the next layer in is the living part of the tree. Get some tree sealer, as you would for major pruning, and put on damaged area.

Ah, I know this as "lawnmower blight".

This tree ~6' tall, perhaps 6' 6" (I say fledgling because I'm

Go take a good look at the damage... are you through the thin cambium layer under the bark? If you're not through the cambium and it's a small wound not involving much of a circumference of the tree, I'd leave it alone. If it's very large or through the cambium, might be a job for bridge grafts:

You heard the lady. Follow her suggestions and you might walk away unscathed.

Best not to seal it with anything. Sealants can invite more trouble than help. Do as Kay says.

Thanks to all for the suggestions. I wished I'd read this thread before purchasing and applying the tree sealer. Oh well, we'll see how it goes. Thanks again.

If you like belt and suspenders, early next spring you can still bridgegraft over the cut. But do be careful to water this summer and fall and please get that mulch on. And around other trees you may have, too. Makes a big difference in the amount of lawnmower blight you see.... ;-)

Feeling guilty for suggesting the tree sealer. But doesn't exposing the heart wood of a tree open it up to serious problems. Yeah, I know, logic is only as good as its' premise but, what is the premise here?

When they've done the experiments, looks like leaving it alone really is the best option as far as "sealing". Turns out the sealer holds in enough moisture to let the fungi grow. Harm done by your recommendation, most likely little. Just one of the un-needed things they're happy to sell you.
