Is my bur oak safe in a storm?
Bur oak is the ice-storm survivor of this group — thick corky bark, dense wood, and a wide deeply anchored root plate mean uprooting is rare even in saturated clay. The failure actually worth watching is the long horizontal lower scaffold limb on an open-grown specimen: it carries enormous ice load far from the trunk, and on an old tree with a decay pocket at the attachment that is the single limb that comes down.
What pruning can and can't prevent
Dormant season only like every oak — it is in the white oak group so the oak wilt risk is lower than red or pin oak, but Indiana's April-through-July rule still applies. The species-specific issue is scale: bur oak builds massive, low, near-horizontal scaffold limbs very early, so structural pruning has to happen while the tree is young; correcting a low limb on a mature bur oak means a dinner-plate wound on a species whose thick corky bark seals slowly.
