Yes, I've used the sweating technique several times with no success. I also use Rhizotonic, etc as recommended by Harry Harrington. I wonder what exact species you're collecting in the US though? I'm referring to Crataegus monogyna. I've found Elm to be extremely easy compared to Hawthorn.

Actually ALL of the hawthorns I’ve collected are monogyna. They’re not native here but are naturalized and have been for a couple hundred years probably. You know, the English brought a lot of things with them when they showed up ?. In fact they are just as common or more common than our native hawthorns in a lot of areas. Tony Tickle is British and all his articles on sweating collected hawthorns are mostly with monogyna, I believe.

If you haven’t had success with sweating collected hawthorns then you are doing something wrong. It’s worth trying to figure out how to do it correctly, the results are phenomenal.

This is a picture of new aerial roots growing above the soil on a collected hawthorn of mine, a couple weeks after collection. This is due to the immense root growth you get from the sweating technique.

Pics of one of my single seed hawthorn, Crataegus monogyna, collected last spring (2017) with almost no roots. Pictures taken today.

And yes, elms are easier to do anything with than anything else I’ve encountered. Pretty much bullet proof.

One of the frustrations I have with Tony Tickle's article is the lack of details. For example, there's no information about exactly how hot it should get or how long it should stay in the bag. Also how you transition it out of the bag. I have asked him some of these questions. Perhaps I've just been unlucky with my hawthorns. I'll keep trying. I collected another earlier in the autumn and will collect another in the spring.

I don’t use Rhizotonic, or anything like that. Or rooting hormone. I usually don’t even use fungicides of any kind. I sometimes will spray a fungicide when the new leaves are emerging but that’s it. You just need solid horticulture. Trees want to live, they don’t need tonics and lotions and snake oils to do so. ?.

I agree with you, tony doesn’t necessarily describe it the best. It was pretty confusing to me when I was first trying to figure it out since I couldn’t find many resources on it. I’ll see if I can post a more detailed explanation of how I do it later today.

All I did when I collected this one was not bare root it much and then stick it in stick above, filled in all around the root ball with well rotted leaf mould from the forest floor around the tree.

Might try an autumn collection for another one - best to do it just before or after leaf fall? They're just started to change now.

I would try after leaf fall. I have not done it myself, yet. Just my guess.

I tagged a couple hawthorns on the farm when flowering in spring. I hope I can find them this winter, to dig up in early spring. Don't know if they are a Michigan native hawthorn, or an invasive EU hawthorn from seed dropped by birds. Either will work.
