There were some questions about growth rates in another thread:
The basic question was:
Welp, as it so happens, one of my coastal redwoods seedlings had some growth issues over the winter of 2018 when it was just a newly sprouted seedling. It was growing under red/blue LEDs but I believe the intense blue light stunted the leader. I've had this happen to a couple dawn redwood seedlings under the same lights as well.
I couldn't find any earlier pictures of the tree, but here it is in August of 2019.
The first picture is a top down view and you can see that the leader stunted and many branches formed to try and take its place...it's what these guys do At the time I thought it would be interesting to try a candelabra style since it seemed that's what it wanted now anyway. I knew if one leader grew too dominant to early, the others would just become branches and possibly even die back. So I wired a number of the new branches to point up so they all had apical tips!
As it turns out...that gives me two trees I could compare with respect to the growth rate question. I have another trees from that same set of seed that did NOT form multiple apexes. That other tree has never been more than about 3' away from this tree. They're from the same set of seed. They get the same water/fertilizer routine. They get the same sunlight. The only differences are genetics and number of apices...so yeah, not a totally controlled experiment, but a happy coincidence none-the-less
Here are the two trees side by side:
Some things to notice: The multiple apex tree has 6 apical branches. It has a denser appearance than it's brother. But it is also a little shorter. The funny brown color seems to be a genetic variance in that tree. It did this last winter too...in fact, last winter I thought I might have killed it as the entire tree was that brown color! The brown is from being to close to the lights. It's the same distance from the same model of light as its brother, but the light seems to be intense enough to burn out its chlorophyll in the winter. Last year, it was completely brown for about 3 months before it warmed up enough to move it outside. Then it greened right back up with no problems! The brown is not the brown or dried up leaves. Also, the foliage feels just like the green foliage...just brown.
The lower ~2" of trunk have been mostly buried the past 2 growing seasons. I could see there is more foliage overall, but the multiple trunks were all mostly thinner than its single trunk brother. I wanted to see what the buried trunk was doing because one would expect, with more foliage above, it to be thicker than its single trunk brother. The tree needed to go into a wider bag to prevent the wind from blowing it over anyway, so, today, I repotted it.
I moved it into a 10 gallon grow bag but planted it shallower. The 10 gallon grow bags I have are ~16" wide. That'll be a much more stable base in our spring/summer winds. Folding the bag in half cuts the volume to 5 gallons. I didn't quire fold the bag in half. I dropped the depth to about 7". So there should be roughly twice as much volume for root growth now even at the reduced height.
Here's the root ball as first depotted.
It's hard to see in the picture (it's pink because the grow lights for these trees are on the wall behind me in the garage) but there are a number of live growth tips on the bottom of the root ball. I did not comb out or reduce the bottom of the ball at all. The root ball was reduced about 2" in height but all the reduction came from the top of the ball. I did remove ~2" off the top and combed what was left of the top about an additional 1" deep but left the remaining root ball completely untouched.
Here's what I uncovered!
It's hard to see, but that last picture is of a burl! I am super excited about the burl!!! I was going to grow these guys out a couple more years before trying to induce a burl on purpose. I've been researching into whether it was possible to purposely trigger a burl or not. I'm still curious...but I have a burl!
By contrast, here's its brother with a single trunk.
It's pretty clear there is additional trunk thickening as expected. The burl adds to it on one side of the trunk...but looks like one side of the trunk only. Anyway, I posted pictures...draw your own conclusions
And the sibling photo with new shoes on the chubbier one
While repotting, I rubbed/cut off all the extra buds that were coming from low down on the trunk...especially from the burl area. There are technically 5 trunks...but one of those branches again almost immediately so it looks like 6 trunks total. One of them is very undersized compared to the others. It's placed funny and looks like it gets shaded a lot. I did put some wire on that branch to bend it out and away a bit further from the others before bending it back up to keep a clear apex on it. I'm hoping it will thicken up some this season now.
I also started trimming the lower branches. I took everything off up to about 6". Any hanging branches below that got a trim too. I didn't touch anything above 6". Once it starts growing in the spring, I'll probably trim some more. I need to learn more about pruning these guys first. I think they are an extension species in which case, I need to be careful where/when I trim to keep buds on branches for next season's growth.
This will mostly be another grow out year. As the year progresses, I'll evaluate how much of the tree I want to start exposing. Overall, I'm quite excited for this one...and it's only 3 years old
Growth rate
So 1 plant grows at rate x per year 2 of those plants will produce double that But what if you compare a plant with one tip vs a plant with 2 tips. If its basically 2 conjoined plants shouldnt it grow 2x per year? Does it?
