Re: How to prune Ulmus glabra Pendula?

\I just wanted to say thank you for replying Greg - your advice was good -
probably mine is a 'Camperdownii' too it had no label - just "special
ordered by Arnhild' :-)

- my tree is grafted about 2 m - and has a good crown in that height, but I
want it taller and wider - and I will have to prune it anyhow because the
branches they reached the ground in 1-2-3.
I know I can try to take a soft shoot early in the spring and form it with
a string or stake - now they are so wooden hard they will break. I think
something like this is what I will end up with.

Greetings from flatland Champaign, IL U.S.A. . . .

In United States, we name Ulmus glabra Pendula as Ulmus glabra
'Camperdownii'.  This may be different from your plant.

In United States, a common internet search engine is google.  I did a google
search for "mature camperdownii elm photo"   Internet reference related the
following. "Young weeping plants often need staking to establish their form.
Many weepers put out multiple leaders that sprawl along the ground. For best
results, pick a central leader and stake it to create a more pleasing,
upright form. You'll need to keep it staked until the trunk has developed a
rigid structure.

Most weeping plants result from grafting the weeping cultivar onto a
rootstock. Not only does this tend to make them more expensive; but it has
the potential to create problems later. Therefore, when purchasing a weeping
plant, carefully examine the graft union, making sure there is no cracking
or irregular growth at the graft. The most effective grafts for weeping
trees tend to be those made relatively high because this helps keep the
weeping portions of the plant off the ground and allows a better upright
form to develop."

Previously, I had asked a nurseryman "How long do you stake your weeping
trees?"  His response, until the day they leave our nursery."

Aggressive pruning, in my opinion, will not encourage this weeping cultivar
to develop height.  Genetic makeup and related weeping character of tree
will be constant, despite pruning.  Also, I am concerned that aggressive
pruning might release dormant buds from below graft union.  Likely shoots
from these dormant buds would not have weeping habit.

Staking is a simple procedure.  Nurseries in USA are currently using hollow
metal conduit from electrical supplier for staking of nursery trees.
Somewhat flexible, but durable.  Tie loosely, and gradually release stem
from staking.  Staking and ties will likely need to be kept in place
(loosely) for more than one growing season.

Enjoy your wishing list tree.

Subject: [SG] How to prune Ulmus glabra Pendula?

I got a wishing list tree two years ago: Ulmus glabra "Pendula"

It grows so crazy much ( 1 to 1,5 m this year shoots! Huff! )  and I wonder
if any body would like to discuss how to form it taller by pruning and
maybe the best time to do it as well
- new shoots are creeping along the ground now - that is NOT how I want it
to be .. so I have an idea I need reaction on:

IF I pruned it now when here is autum in September - that would be the
pruning time that cause less regrowth - this I know from apples trees
researches.
Pruning deciduous trees while they are in winter dormancy will be the
pruning time the gives strongest new growth. I might try to make a half
bark  ring on the trunk as well to retard it some, but that still don't
form the crown

But I also want it taller - the crown - I know I can try to form up a
branch or three, but ... so I have a wild idea about pruning more or less
all branches very strong NOW - and see what happen next summer? or . do you
think I can risk an even more weeping tree

I could of course play with it like it was a bonsai with wire  to form
the  crown -- but that is maybe  too much job - I think so

- but what I know for sure it is that I can not let it grow like now ..
creeping around on the ground

Ulmus glabra is one of my favourite wild Norwegian trees -- but since it is
so big growing I could not plant that in my garden - so this Pendula was a
compromise .. at least I got ONE Ulmus I thought ,, it was very expensive
and I really need god advice because I want to keep it of all my heart!
