Site factors to consider
- Critical: Cold HardinessThe average low suits it fine; our real cold risk is the swings, late frosts, and intense winter sun, so wrap young trunks and give it shelter.
- Watch: Short LivedFast but not forever; this one runs short lived here, so enjoy it and plan a successor rather than treating it as a legacy tree.
- Watch: SuckersIt throws up shoots from the roots and base, so plan on cutting suckers to keep it from turning into a thicket.
