Can I use freshly cut trees to build my Growboxes?

I am clearing trees from my land. Can I use those trees as my "frame"
around the "box"? If so can I use them while still green or should I
wait till they are aged?

Group:

You can certainly use trees to build your frames! If you can at least square
them off they will be easier to work with and not take up so much room. Slicing
the trunk into 2-3"-wide boards would, of course, be ideal.

Green is fine. Just be sure that you place stakes several times along the
length, so they don't move.
