Cutting Black Locust

 

Before

Before

These trees were in the seven-to-nine inch diameter class. This picture was taken from a slightly different angle.

Extrapolating from the area of the cut stumps, I dropped enough Black Locust on the ground today to make another 500 hours of burn-time after they are turned into firewood.

This is the tree I cut two days ago. I know the photo is poor, but if you look inside of the area outlined in red you can see evidence of where this tree had been cut down once before.

Black Locust suckers profusely from its roots. All of these trees are the same "clone".

I count 15 rings and it has a 9" diameter stem. Not tropical-hardwood growth rates but not embarrassing, either. Black Locust heartwood weighs about 48 lb/ft^3 or 75% the density of water.
Black Locust responds well to clear-cutting. The roots will send up shoots thicker than the hairs on a dog's back. After three or four years, prune out the ones with the crooked stems. The rest will grow quickly, relatively straight with few knots.

  1. well, it does burn great but you have to let it get REALLY dry.
    like 2 years in the wood pile. one year is not enough really.
    got some to burn a few years back. looked good, lots of drying cracks on the ends. but boy, oh boy did it gunk up my stove !
    one of the "old guys" told me that is why they used it for fence posts as it didn't rot like other wood.
    it does make great firewood if dried right or long enough.
    just split it into smaller chucks than you would otherwise and let it dry out for a year or more and you find it makes a great overnight load for your wood stove.

  2. It's good for 'pollard' trees. After you mentioned it some time back I cultivated some oaks into Pollard trees. They're already proving useful.
