When do trees grow?

[sharp edge]

I see the F/F members are doing a lot of crying  about the weather were having. I like to see it 20 below, because the trees like to grow in this weather ( i think). Was going to do a experiment to see when they grow, but thought it would be easier to just ask here. Thank you.

  Top secret stuff. Do the experiment.

I thought they grew when you planted them.

No thanks, been working to hard on a top secret barrel stove, if it works out will share it with F/F. Here is the tree experiment,may be some one will try it.

1)Find popple tree 10"-20"(DCH) wrap ele. tape around it.(in Canada use duct tape)
2)Drill 1/4" hole 1" deep put wooden pin in it.
3)Tie a piece of fine wire to pin--put a small wire spring on pin too. Run wire around tree tie on to spring.
4)Mark the spot where spring and wire meet. Check twice a mo. for a year and see when it moves.

I think it would move different on different kinds of trees. On popple it would move at 20 below when all of its water pipes (cells) would swell up and brake. The place between bark and wood would swell the most and next summmmer will  turn into wood. I'm i a red green red neck or what.

Reminds me of the experiment when one feller climbs the ladder with a cup full of water and places the rim to the ceiling. The guy below takes a broom handle and places it on the bottom of the cup to hold it in place. The guy on the ladder lets go and comes down the latter.

he must have better luck than I do then, only about half of em grow when I plant em  
the other half gets ate by deer, rabbits and or some sort of big lawn mowing device driven by one of the family (lord knows I haven't run them ALL over )

Here's a test pretty much like that tree growing test. 
Hang a ladder, with 1' rungs, off of the side of a ship such that it touchs the water at low tide.
Wait until the tide has risen to full and then measure how many rungs of the ladder have submerged to give you the number of feet of the tide.

Ya almost had me Tom...... almost!

I was about to ask if that was a joke or not.

I didn't think that trees grew in the ocean???

[Tom]

You never heard of Atlantic White Cedar or Pacific Madrone?

[WDH]

You got a point, there...............

Ya musta gotta skuttle dat ship first ta measure da tide dat way. 

Wouldn't dat a been rare if'n ya caught da Furby on dat one.....

[Tom]

Pretty rare indeed.

I noticed DCH instead of DBH

Are we being politically obfusicating or is that CHIN height for reading the spring?

If yer studying poplars from a boat I'd bet spring has sprung

trees grow when you ain't wachin em. You go for years and never see any change and all the sudden you notice they be a lot bigger. LeeB

Look in Oliver's and Larson's Forest Stand Dynamics, Chapter 3.  It varies with the species.
