Shantung on crack!

This 2 year old seedling is on some serious crack as it approaches 8'. Any ideas why it would put on so much vertical growth in a short period of time? Surprised to see its not putting on any caliper or horizontal branching. No ferfilizer, part shade and normal deep irrigation if necessary.

Not really complaining just a strange sight around here.

This was a temp. location until the plants put on some growth. Looks like I have to move this one in fall.

From the looks of it, you're going to have to stake that tree up for a long time. It sure is putting on some height fast!

Yeah I tied that thing up a month ago with a 6' bamboo stick and it grew another 2' in June. I wonder if full sun will encourage horizontal branching. If it continues on this pace I'll have to cut it back.

I have a sugar maple doing something very similar. I don't have any reason why it's responding so well though.

I've only seen a cottonwood and silvermaple put on 4' in one season. Those are huge 100' trees though.

I thought Shantung was more in the mature range of 40'.

Your trees are so pretty. I love when you and others post pictures.

My theory... it is wind protected and supported. Why would it do anything but take off?

A few of my back yard trees did similar but slowed once they grew above fence-protection and got into the breeze.

Just guessing though :-)

I suspect due to partial shade it's channeling resources into growing height to compete, much as a young tree might do in a forest (say, in the temporary partial sunlit patch created when a large tree has fallen.

Hence tall but spindly & can't support itself.

Grow may also slow when you move it, which will severe a lot of the root system.

That theory makes sense since many understory trees look like that. Little sibling is half the size. Yellowoods are half the size of that one.

It was a little plug last year so I'm curious as to the size of the root systems. Its somewhat sandy here so it will be easy to keep the integrity of most roots unless they really have spread.

Don't cut it back. Let it go on its' own.

I have a English oak that is growing the same way. It is in full sun too. It did about 5 ft last year and 3 or 4 this year so far. It is tall and spindly and the 2 others I have from the same parent tree are about 1/3 the size of it, go figure.

Late to the party, but I would tend to come down on the side of the shade being a major factor. Note the leaves grow larger as you move upward. But I don't think it's the only thing. I also notice in the lower right corner, just how green that grass is. I bet your tree has found the lawn fertilizer as well, and that will also result in the larger leaves near the top. High fertilization will make longer thinner growth, and usually larger leaves as well. Some fertilizer is beneficial in many cases, but too much causes it's own problems.

Neighbor's red oak on crack!

This tree has been a single shoot until the last two or three years. The sunlight theory may be on the right track. They water and feed their grass heavily, as well.
It is interesting to see a Shantung like yours. Mine has always tried to be a shrub, constantly sending shoots out from the trunk (in full sun and wind).
