A tree can grow back from its stump, but full regrowth is unlikely (especially for more stubborn conifer trees). Instead, trees are more likely to send up a number of shoots from the dead stump, which will try to develop into primary stems over time. In other words, it will start to look increasingly bushy. The goal of killing and drying out a tree stump is to prevent that from happening, as well as make the stump easier to completely remove.

According to scientists at Penn State University, spotted lanternflies do not typically kill the trees and plants they feed on, but they can cause branches and segments to die off. However, they have been found to kill cultivated grapes, which can have devastating consequences for vineyard owners and regions that heavily rely on vineyards to create jobs and generate revenue. They have also killed the Ailanthu altissima, known as the tree of heaven, though this is classified as a noxious and invasive weed tree.

Only trim palm trees as needed, which is usually about once per year. However, don't stick to that schedule if the palm tree doesn't need it. Avoid trimming palm trees when possible. It’s best to trim palm trees only when you notice a buildup of dead fronds. That said, leave the brown fronds during the dormant season because this organic matter helps protect the tree from the cooler weather.

If you want to take your tree-planting hobby beyond your outdoor space, here are a few great ways to do it:

• Encourage your neighbors to participate in the Arbor Day Foundation’s Tree City USA program, which has a four-step framework that helps communities grow and maintain their own tree cover.

• Support businesses that plant trees. 

• Lobby your local government to plant more trees around your community.

• Donate to a tree-planting charity.
