Thorny Locust tree

Mark,

I have been following this subject with interest because I don't know what a locust thorn is like. Dang, your photo sure brought the stories to life. You all with locust trees need to be looking at dozers and armor!/w3tcompact/icons/smile.gif That is one mean looking thorn.

Yep, Armor.... that's what I need. Those thorns are in bunches up and down the trunk and all over the limbs. I have been stuck pretty good several times. I am real careful dropping them with a chainsaw.

Gentlemen,

My parents have a property in Australia and as they have got a bit older, they have leased the place out to a neighbor to run his cattle on for grazing and for baling hay and making silage. On the tilled areas the land has remained in good condition but in those areas left for grazing alone, there onle Honey locust has run rampant. We have had a problem with them for years but now they have really spread. When I head home to OZ, most of my holiday time is spent dealing with these bloody things and I have had a bit of experience dispatching them back to the **** they came from.
1. Use proper safety equipment, wear long sleaves, good thick leather gloves and absolutely wear eye protection. Have some anti-inflamatory / topical anaesthetic cream on hand too. You will know why when you need to use it.
2. Try and get them before the fruit (black pods) have set. That is how these things propagate, and birds and cattle love them and will deposit the seeds all across the paddock as they are not digested. So before you fell the tree, make the effort to pick up as many that may already be on the ground, bag them and properly burn them.
3. Leave the tractor in the shed unless you have highly pucture resistant tires. My weapon of choice is something with tracks and a blade but a D9 would be a bit over the top. (many of our trees are mature).
4. If you have to pull it over, make sure your chain is long. You absolutely do not want these mongrels coming through your tractor cab.
5. poison the stumps with glyphosate or some other broad spectrum herbicide if you are going to leave them there, otherwise rip them out of the ground.
6. be careful of those around you once chopping the felled tree as those thorns can go flying some distance if grabbed by the chain of your saw.
7. Get into it, but be aware that these thorns actually hurn more than they look and the do look ferocious. The swelling and pain is immense from even just a small injury.
8. For the small stuff, poision the foliage, come back a couple of weeks later and rip them out.
9. Make sure your neighbors do the same thing. Those seeds from the black pods spread easily via birds and cattle, they are relatively fast growing so you need to do the job thoroughly and over a broad area.

Hope it helps. Be careful. These are a bloody awful species that can really get out of control and they just become exponentially harder to remove over time.

Don't have much to add other than to agree that these trees are very nasty. They can be pushed over with a tractor FEL leaving the root ball exposed. Then go back and push on the root ball until the entire thing is tatally uprooted. However, the roots are very deep and stubborn, probably the most aggravating tree I have ever tried to totally uproot. A word of caution, be prepared to say words that will later make you ashamed you said them.

we have some of the honey locusts. Wife calls them the bit** tree. deer love eating the pods. Didn't know they were so hardy and strong. Will probably cut some for firewood cuz she wants them gone. yippee seat time
:D:D

We have a fair amount of them :( Safest way to get them out is with a bulldozer, no flat tires ;-) Actually I had a contractor clear one pasture last summer while he had his dozer here for other work. Pushed them into a big pile that I'll eventually burn.

I don't think honeylocust (BIG thorns) is as good as black locust (little thorns) as far as fence posts go.

I can see how people used the thorns as nails. Here is a pic of one I pulled out of my tire. Lucky it was the little thorn on the side and not the long part that stuck in my tire.

As Crocodile Dundee would say. "That's not a thorn, this is a thorn."

Sorry, I couldn't resist.:D

Black locust is one of the most valuable trees IMO. Great fire wood and great building lumber, last for a very long time. Black locust will easily out last any treated timber bought at the box stores{lowes home depot etc..}

Ya got that right! I had to remove a 6x6" post in my basement tht was set in the mud at leat 40 years prior as near as I could trace it. Rotted by the looks "I'll just give it a good whack with the 10 lb sledge" BOING! Finally cut it with chainsaw (hint, don't do that if you are standing under a fire alarm, it gets noisy). The rot was just skin deep, only went in about 1/8".

The "old timer's wisdom" about how to tell if a black locust post needs replacing:

When you set the post, put a rock on top of it. Every few years, come by and check on the rock. If the rock has rotted, it may be time to start thinking about replacing the post some time in the future.... :D:D:D

Now that's black locust, not honey (big thorn) locust.

BTW, I've heard that the bark should be removed before setting the post.

I've got Honey locust all over my property. The young tree's have thorns, but as they get older the thorns go away. The wood is the only type that'll throw sparks off my chainsaw chain. Hard as nails, dulls saw chains up real fast. That stuff burns HOT.
I've heard the old timers tell of making beer with the seed pods as they are very high in Fructrose. Never tried it myself, but it sounds legit.
ETA: I bent my loader arms pushing them down. Once they set up in clay, they don't give up easily.

Hand an unpleasant surprise today while running the log splitter - happened to glance at a locust I planted over 30 years ago. I ordered Black Locust but in only a few years it was obvious they were not the 'black' variety. Big, long pods so I figured probably 'shade master' whick IANM is a thornless Honey Locust. Okay, just there for for a bit of windbreak (2nd row) so no biggee. Well, one of them now has those vicious thorns, maybe reverted to type? Anybhow, tree - meet Mr. Chainsaw.

The Honey Locust with the big thorns does not drop their thorns as they age, they are there for life...along with all the thorns and stuff on the ground under them. I saw somewhere, years ago, that the settlers used to use those thorns for nails.

The Black locust has small thorns (very painful though) only on 1-2 year old wood.

Here is what I've done to a lot of my Honey locust (hint: 90HP Felcon).
btw, the older Honey locust I have on my property have no thorns. The young ones do.
The tree on the left has massive thorns. The ones in the back are older and have no thorns.

Wow! Very nice. I want to clean out some of our woods like that. Your place will look very pretty when it greens up :)

If you are not using the Felcon, I can store it for you....for free even! :laughing:

I'm getting a brush mower for the skid steer. I know it won't do as pretty of a job as you've done, but hopefully I'll be able to do a half decent job of clearing some areas. Of course it won't do anything for the bigger honey locust trees.

got to love when a brand new forum peep resurrects a 9 year old thread.... :thumbsup:

Hahaha! Just noticed that! We have so many of these pests that eradication is an ongoing concern and it began long before the blog was started. Some interesting comments though. I have never used the wood for household firewood or fence posts but that seems to me to be worth giving a go. In Australia we have very stringent fire restrictions and it is not easy to get a licence to burn off piles of wood or farm refuse. I thought about putting it through a wood chipper for garden mulch, but the thorns would still be a concern for kids, pets and the lawnmower.

I do also have one other plant pest that I need to tackle, and I do not know if any of you good people are familiar with it and I do not recall ever encountering it on any farms or ranches in the US. It is called African Boxthorn (Lycium ferocissimum). It is not a tree, more of a shrub with smaller needles, quite resistent to Roundup and if you want to cut it, you WILL loose a bit of blood. I have found in the past that if I throw a chain around it and rip it out, it can re-emerge from I guess to be remaining root tissue. I can tell you that I have put this on the fire before and it is a great burner, but forget it for fence posts as the branches are quite gnarley.

Any ideas?

I could not pass this one up even though I am new the the forum I can see this is an age old issue. The front acreage I cut them with a chain saw and drag them off before the have a chance to dry out. The smaller ones I am cutting off with very long handle hand cutters and throwing them in a trailer with twine I can tie them up afterwards connect the twine to a tree at the dump location and drive away.
