Wych Elm, so I'm told, is usually found growing near water and has a straighter grain than Common Elm, perhaps because it grows faster, being near water.
I have some elms to come down soon, before the dreaded disease returns. They aren't very big, 8" diameter at the most. They are growing close to a stream! Not sure what I am allowed to do with them under the regulations.
I might be able to get some fairly straight c8 foot lengths out of them if anyone is interested.
I thought they might be good for wagon shafts, but I've been told they will be too heavy. Certainly tough stuff! All the local flat-bottomed boats used to be made of it, and coffins of course.
