The 2023 Yamadori/Collecting Thread

In prep for the 2024 collecting thread: Now that I’m back in the Midwest, I have access to a pasture of cattle grazed, Siberian Elms (Ulmus pumila). Some are upwards of 50yo or older. But from age, drought and/or pests, a lot of died in the past few years. I missed the window collect.

But what prep can I do before collecting next year?

They will be leafing out now. May and June are the wettest months. The soil is a very sandy so they likely have deep roots. I’ve cut a large diameter circle with a sharp spade around yard trees in the years prior to collection to stimulate back rooting. But with likely deep, thick tap roots I’m not sure that will do much.

Maybe I should partially excavate one 1/4 and remove a couple larger roots? Should I fertilize this year in the ground?

Here are some examples, not necessarily the ones I would collect and one is dead or mostly dead. Thank you!

If you have access to many and some are dying, why don’t you try to collect some right now?
 
@hemmy I'm in the "go for it now" camp. Siberian elms are so hardy that any root at all will be enough. I've dug and chopped them in the middle of summer, full leaf, and they did fine.
Yes, they have that central tap root, but that tap root sends off feeder roots laterally along it's entire length. Even if you don't get those, the tap root will be enough to sustain the tree as it produces new ones.

And if you're finding them in a cow pasture, you REALLY don't need to worry about fertilizer. The cows are doing that already.

Yes go for it. After going for it with BCs, I now will not hesitate to collect BC all the way through mid summer.
 
I'd be very careful collecting out of season. I've killed several very nice cedar elm (which when collected in season are bulletproof), by digging them when they've leafed out for only a week or two. If you value a particular specimen, I'd be patient and leave it for next year...

Some species won’t miss a beat, no matter what time of year you collect them, but it’s never a guarantee that any particular individual tree is bulletproof. If you’re collecting valuable, naturally-dwarfed, true yamadori trees, don’t take the gamble. If you’re digging up weed trees along a fence row, go for it.
 
If you have access to many and some are dying, why don’t you try to collect some right now?
Time and space mostly. I won’t be down there for a few weeks. There are probably ~200 elms that are pretty old and beat up. Some are getting out-competed by Eastern Red Cedar saplings from bird droppings. Oddly, bag worms hit the elms hard last couple of years. Odd because they were usually conifer problem and city problem on landscape juniper. But I guess 2021 was a record year for them across the Midwest and South.

I’m hoping to end up with 1 nice one.

Thanks all for the advice!

Great trees!
I'm not sure if this would be beneficial or not - you could try it on one of the trees: Dig out about half of the rootball and cut any large roots you find in that half back closer to the trunk. Then fill the hole back in with pure pumice.

Good idea to not put back the native soil. But I’d probably go with potting soil and bark/sand. They wouldn’t get watered and I’d want something that held moisture but doesn’t get hydrophobic.

Also I’m guarding with my life, my supply of pumice that I hauled across the desert SW! That stuff is like gold now, no way I’m throwing it in the ground!
 
Dug this beech out of a bank in Pennsylvania last weekend (family owns the land, and I asked them permission) Hoping for the best. Should I chop the top off of this?View attachment 484218
Real nice beech material,,I’m realizing I haven’t even looked at the date yet

Sweet canopy ! Choppin it would kill me lol they take so long to develop that I would personally go super duper slow as previously recommended ,then again wtf do I know my only beech I’ve had for few seasons has wound up dead this year lol it’s a real whodunnit

In St. Louis you can get 1.5 cubic feet of pumice for under $20 at some of the hydroponic grow shops. I'd bet you could find similar deals in kansas city (or worst case scenario, make the drive to StL).
 
And it's dead.😐

Stupid 🤬 dog ripped it out of the pot.
Then I put it back into the pot, hoping for the best.
Then he ripped it out of the 🤬 pot again!

I'm not going to pretend it can survive collection and two repots inside of a month.
It's a 🤬 shame, too. That one had allot of potential.

F🤬er got that scrub oak once too, but it's still mostly dormant so I'm putting it on the top shelf while I work on training the dog.
This is so frustrating and I'm sorry to hear! For months after I got my first cat I lived on high alert. He was only a few months old and constantly knocking over my tropicals, spilling soil all over the ground, messing with my vegetable starts. I resented him for it! But he has calmed down quite a bit and never messes with my stuff anymore. His tastes have refined with age... I hope your pup's will too!
 
@rockm makes a good point about timing that brought to mind something I hadn't thought of earlier. Right NOW might not be the best time if you're hopes are hi for a particular specimen.

I'll modify his and my previous statement with this: specifically speaking of Siberian elm, you can dig and chop all the way into summer if it's healthy, but wait until the leaves harden off. Right now it's focussing on putting out foliage, not roots. Once the foliage is hardened off and in full energy production mode, the tree will shift focus to growing roots and storing energy. THAT'S when to dig when you've missed your early spring window.

He's already figuring it out slowly, but I'm not where near trusting him alone in the yard all day.
We're working on leaving all pot related things alone. I've placed literal sticks in pots of various styles all round the yard as decoys, and training him to treat them the same as my actual trees. He can take all the ground litter he wants, but if it's in a pot, leave it alone.

He's clever as hell, but a little too quick on the uptake sometimes. I accidentally busted him in the chops with the tug-o-war rope and now he thinks he's not allowed to play with it.🤦
But he should have trees in pots down pretty quickly.
 
Didn’t know what these two were when I collected back in February.
This one turned out to be an Amelanchier (serviceberry) with a very sizable trunk for the species.

And this one turned out to be a buckeye (sad). I guess I’ll see if the leaves reduce any.

Yeah I really like how it looks as is. It would make a nice clump style, but I will probably leave as is. I was worried that with all that canopy it would be harder to recover digging it up
