Anyways,all is not lost.Get a stock Zelkova plant,perhaps from Evergreen Gardenworks,and take cuttings.
I took about twenty cuttings from the trees from 2013, softwood in third week of May,and by the first day of Summer I was rewarded with 100% success.
They were struck in a propagator in shade of trees with lid on in pure peat moss and dipped in cloning gel.
I am thinking slender,tall forest trees.But of course you can make brooms from these too.
I am taking cuttings this season too and am going to make brooms from them.Should be cool.
They are all planted in a growing bed now.
Some grew to five feet in the first season struck.
The plan is to get them to about one inch trunk then start layering sections for tall forest trees.
Branches will be pointed upwards this season though.
And then if the bases of the cuttings have survived any crown gall,which happens to me sometimes with seedling planted in garden soil,I will make some clumps from chopping back a lot then do an air layer on it.
These cutting have waken fast and are going to really grow this season in the growing bed.
I should have 1" trunks by the end of the growing season and I can start layering the sections next year.
It is quite funny how all my Zelkova in the ground and everywhere,except for two,will have been propagated from cuttings of the first seed grown batch.As will be the cuttings this year also that I make brooms from.
