It's funny I think there is a lot more to this aesthetic issue than meets the eye. Many aspects of tree work are over focused on aesthetics and more landscaping or clearance based than tree care based. So we need to try to overlap landscaping and clearance with tree care. Raising can often be done with reduction cuts instead of limb cuts, as outlined by the isa. Back to stubs. In hydro clearances, I suspect workers are often instructed to cut stubs off or not to leave stubs. Stubs are bad and ugly but often, trunk/ main stem cuts are prettier but worse, and create risk that is so far in the future that it is not considered. For clearance managers, stubs may shoot and they don't want to come back too soon. But large trunk cuts will shoot worse? I'm not sure, I rarely make them. I think in many cases, making a stub/nodal cut instead of a stem/trunk cut is likely a good trade off. Often codit would be working a few feet off the stem/trunk on a couple 4" wounds at a node (even if no remaining shoot exists...at the moment) instead of an eight inch wound on the trunk. It's like the aesthetic balance of a tree. Many of us are familiar with the average folks who think an unbalanced tree will fall over as if it is somehow balancing on a dime. Not that lean is good but in the majority of open grown leaners it's the last issue and limb failure is still more likely than whole tree failure. The lean is ugly but not always problematic in urban setting. I recently saw some poor hydro cutting, which in my area is usually well done, or at least as well done as it can be. Often those guys don't get the credit they deserve. We all use power. Even more credit to those who live off the grid. Anyway I saw some horribly flush cutting on white pine. It makes me think that quite likely, it would be far superior to leave 6 inch ugly ass stub cuts than to make a cut that is an inch too close. A good collar cut is best but a cut anywhere beyond that will be better than a flush cut every time. The main point I'm trying to make is that hydro clearances could be more ugly but more tree friendly if they included nodal stub cuts as an option. But I'm sure that would be a tough transition as most arborists still think stubs should always be removed. And people who aren't arborists will criticize the work for being ugly. On the other hand, once the stubs flush (think oak or locust), the appearance will be better than a whole in the crown with a section of bare trunk. Once again it depends on the details and exceptions to the rules. Name a general rule and I'll present a solid exception. Rubbing, spacing, codominant suppression, 1/3 rules, deadwooding, remove damaged limbs. I'm sure many of you know some of these exceptions already but if you are curious let me know. As you know I could talk about it all day.
