In any open stand frequent prunning is the only way to "push" the stem
up for clearer butt log lengths. Rule of thumb we use on walnut and
other high value species is to prune to keep half the stem in limbs,
from about when the tree reaches 20 foot or so in heigth, and annually.
Early spring prunning tends to let the limb scar heal faster.
