Near my garden, there is a hedgerow of black locust where the owners of my plot do their winter coppice harvest. It tends to expand, as you may know. Some of it is expanding into my area.

I was wondering if I could go the way of "if you can't beat 'em, join 'em" and graft something fruit-ish onto the black locust as it invades. I did some searching on the internet, and I'm coming up blank.

They keep telling me I need to cut it back ASAP, or it will get entrenched. It'd be nice if I could get that invasiveness to work for me instead.

I'm open to any and all low-tech and low-investment ideas. If, in the end, the idea involves a shovel, I would also consider that.

Thanks.

The black locust that I grow don't spread.  They will come up from seed but not many.

Sounds like honey locust to me.

The black locus on our property does spread. It keeps popping up in the pasture, but it gets mowed. Also an Amish friend is going to send his kids over to dig up some to transplant. From my perspective it has at least two great uses: first it makes great rot resistant fence posts and it is a huge nector and pollen source for the local bees.

An interesting question:  would it still be a nitrogen fixer if the top half was an apple tree?

Yeah, I'm seeing how difficult it is to tell the difference. Can't come up with the answer online. Might have to take some pictures next time I'm out there. It has thorns, not that long. The bark might have thorns, have to check.

Then, as for nitrogen fixing: "Honey locust roots lack the nodules common to nitrogen-fixing legumes.  Apparently, the question is still unsettled, since a quick search of the web reveals sources that claim that it does indeed fix nitrogen, and sources which state it does not."

Whatever it is, It'd be nice to graft a tree on top of it, one that is more useful to me. Especially when there are so many volunteers just pleading with me to graft them

After some further consideration, I'm getting more convinced that they are black locust.

Evidence:
--Everyone here calls them "Robinia" (italy/italian).
--Wikipedia says they are pretty widespread in italy and my region in particular.
--I don't think there are the red bark needles that typify honey locusts.
--Wikipedia says the honey locust is present here, but mainly as an ornamental, and is called "Lo spino di Giuda" (Judas Needle).

So...how about we graft a couple and see what happens? My neighbor has an apricot, a plum, and an apple tree. Pretty sure I can get some cuttings.

In other news, I saw a wild apple tree where I work. It puts out wild apples. I could either graft from that or try to grow the tree from a small branch. I've Already taken an apple from it for the seed.

I would love to know if any fruit trees can be grafted onto a black locust, I have a huge stand of locust that cranks out seedlings.

Me too. I found this at
http://sdhydroponics.com/resources/articles/gardening/grafting-plants
"All kinds of plants can be grafted including fruits, vegetables, trees, bushes, flowers, but not all plants can be grafted together. The only real way to tell if it can be grafted is simply to try. But generally speaking plants that are closely related graft together best, and form a good graft union.  A poor graft union usually results in plants that either grow poorly, break off or just eventually die."

I guess we can have a go at it...gotta do some more research to find out when, how, and find a decent scion.

I'll post here any amendments of findings.

I copied the below from http://www.n8ture.com/hort.html. That is about as clear as the "rules" can be. Certainly you can try other things but these rules reflect the best possible results for trying.

Compatibility: Not all plants can be grafted successfully. In order to produce a good graft union (the growing together of both plants) the plants should be closely related botanically (the stock and scion must be compatible).

The following rules apply:

Plants of the same genus and species can usually be grafted, even if of a different variety.
Plants of the same genus but of a different species may or may not unite. If they do unite the union will be of inferior quality.
Plants of different genera are less successfully grafted.
Plants of different families will not result in a successful graft.

Based on this I checked the more common fruits most of which are in the Prunus and Rosaceae family. I did not find any fruits in the Fabaceae family. Your best bets for grafting for something else useful might be Acacia or Mimosa.

Good Luck,

Jeff

Hello,
I realize this is an old post but I am currently considering trees to experiment with grafting to honey locust. I don't want thorns but would like something to produce nitrogen. Will this work with root nodule producing trees grafted to non root nodule trees (honey locust)? Did you or anyone have any luck? Which trees do better? Any fruit or nut tree success or failures? Please, any input will be helpful.
Thanks

I have no locusts but do have leguminous trees in the pea family - mainly leucaena leucocephala & gliricidia sepium. These grow well in our hot dry climate, but peas dont, especially in summer when it hits 40C+
Maybe I can graft peas onto these trees, in the shaded area of the lower branches?
