Subject: tree types
I want to use a willow tree with a diameter of about 6'. Is wind really a issue?

Subject: Willow?
I'm guessing you mean 6" (Six inches).  I'd be amazed to see a 6 foot diameter willow tree.

My understanding is that Willow trees make poor choices for tree houses, they're too flexible.  Plus I'd be nervous with a 6 inch tree of any sort.

This is a weaping willow if that helps and is about 5 or 6 feet not inches.

I have seen many weeping willows with trunks in excess of 5 feet. Unfortunately willows sway a lot with the wind and I have seen just as many 3 foot branches come crashing down in a storm.

Why don’t you go in for a Sawtooth Oak Tree? They are sturdy, resist diseases very well and can reach a mature height of 60 ft. Besides having a strong root system, the trunk of a Sawtooth Oak Tree is very stable and bears well against wind. These trees are planted as shade trees as well due to their dense foliage, which can alternate as a privacy screen for your tree house. They are certainly hardier than Weeping Willows.

Subject: Ash Tree
Hi all,

I have a large Ash Tree (50' +) near a swing/slide set that has a platform, and I am interested in building across the span to the ash to a tree house there.  I am pretty comfortable with all sorts of tools, and have done pretty major house renovations, but I am concerned about the possibility of damage due to sway.  The top of the tree can sway pretty significantly in the wind, and I'm looking at building about 8' to 10' off the ground (it's on a  side slope).  The tree itself seems healthy, and the way I envision the house is hanging off one side, wrapping about 2/3 the way around the tree.  Two major branches on the bottom would support the platform - one crossing over to a 6x6 post of the playset.  One corner of a vaguely triangular shape would be knuckled, or perhaps cabled.  Given what I have been reading about the possibility of tremendous forces, is this even possible?  Or am I simply going to build an elaborate pile of crushed lumber at the bottom of a tree?

I'll try and figure out how to upload some photos so you can see what I have in mind.

Many thanks,
Tony M.

Subject: What about loblollies?
Hi all,
I have 3 loblollies close together that would work very well. The only problem is: they are loblollies. They move a lot. They do have some caliber (all have @ 10-12 in. caliber up to about 8-10ft up). Like most of their species, there are no branches until higher up in the tree than I dare. The circumferential growth is much slower than the vertical. As softwoods, they are not particularly long lived, but would last at least through my kids' passage to adulthood. Hurricanes (an occasional hazard in NC, though we are pretty far inland and they usually just result in nasty thunderstorms) do knock them over sometimes.

Is it possible to use these trees? Has anyone successfully used loblollies? I have no other options in my backyard. What would people recommend for flexible joints? How high would you have to build given the increased sway of a softwood? Is there a particular design or technique required?

Answers to these questions will help me convince (or add weight to the concerns of) my safety conscious wife.

Thanks and hoping for supportive arguments (haha),
Dave

Subject: Alder
Hi folks!

My housemates and I are considering the construction of a treehouse, using 3 alders (14" to 17" in diameter each) as base trees. We'd like to build around 10' to 12' off the ground. Does anyone have any experience with alders, or know any pros or cons about using them?

My brother tells me that:
a) they are not considered "structural" wood, so far as carpentry is concerned.
b) they are comparatively short-lived (40 to 60 years, or 60 to 100 years, depending on type), bringing into question the wisdom of building in them.
c) they have irregular grains, causing them to have fairly poor shear strength.
d) he would not build a treehouse in an alder.

Bearing this in mind, I'm curious if anyone has success stories, because alders are the only trees of sufficient size available to us (on our property).

Thanks!

Derek
