Light-bark trees are most notorious for producing lots of sap when wounded. These varieties include maples, birches, poplars, dogwoods, magnolias, and elms, and they will bleed more when the trees are dormant. That’s why it’s a good idea to prune them in the summer months rather than waiting until winter.

Bleach can potentially kill some types of delicate ornamental trees, but for the most part, it will only kill the foliage it comes in contact with. Applying bleach is not an effective method of killing a tree. A better option is to use an herbicide, which is a chemical compound designed to effectively kill a tree. 

Pruning can impact cold hardiness—but it’s less about the exact temperature and more about temperature variation. Generally, you don’t want to prune trees when there’s a risk of temperatures suddenly dropping from 50 to 60 degrees Fahrenheit to 0 degrees Fahrenheit or below. A tree is most sensitive until 48 hours after it’s pruned.

Yes, it is essential to confirm that any tree service company you hire is properly insured before they begin work. Tree removal, trimming, and pruning are dangerous jobs, and proper insurance protects you, your home, and the company from liability in case of accidents or damage. Look for a company that carries both general liability and workers’ compensation insurance, and do not hire one that cannot provide proof of coverage. When browsing for professionals, you can look for indicators like an “Angi Approved” badge, which signifies that the business meets standards like holding applicable licenses and passing a background check. Keep in mind that a license is a legal requirement to operate, while certifications are typically voluntary.
