+ Provides nice shade, and chestnuts which are in principle edible. Contributes some variety to the street tree pallet.
- Looks pretty funky with all the "pruning" to clear the power lines.
A large Chestnut (Casanea sp.) a mature tree with a single trunk DBH 20". Live crown ratio is around 50%.
New foliage looks healthy. Some large dead branches. Many points of multiple attachments presumably from earlier heading cuts.
Street tree with good southern exposure. Level ground, no direct irrigation except in adjacent lawn.
House, cars, power lines.
Very messed up crown. No dominant leader. Bushy growth from earlier heading cuts.
Part most likely to fail: branch failure. Severe failure potential on moderate parts with moderate targets for a hazard rating of 3+2+3 = 8.
Corrective pruning. Rationale: Branches with week attachments should be removed or pruned to manage end weight. Branches which are growing around rather than into the power lines should be favored. General cleaning of dead wood is in order.
I should really figure out how to use the chestnuts this fall (the neighbors said we can have all we collect).
