Sudden oak death and oak wilt are different diseases. Oak wilt first shows up in tree leaves while sudden oak death affects the branches and trunk. However, as symptoms in both can overlap, it’s best to consult a professional arborist tree expert for a proper diagnosis and development of a treatment plan.

If you’re taking down a tree that you don’t suspect is affected by disease or pests and it’s nowhere near your home or other structures, then calling in a tree company should work fine. However, anything more involved means an arborist is a better option. These pros have years of experience with tree removal and can safely take down trees located next to structures, and they have the tools, sanitization equipment, and experience to remove sick or dying trees without infecting nearby trees. 

While there is a lot of debate about whether boiling water is strong enough to kill tree roots, it is not best to remove the roots from large, old trees. You may be able to weaken young roots enough to remove them manually, but boiling water will likely not do the trick for large root systems.

The recovery time for pruning depends on how much you prune, the species of tree, and how well you care for it afterward. All trees grow new wood and often sprout additional branches after pruning. Ideally, trees should recover from normal pruning after one or two years. Heavy pruning or slow-growing trees may take several years to fully recover.
