After a big storm, you may not be sure if a tree was struck or not. Look for the telltale long scars, like strips or gouges in the bark of the tree, running in sometimes jagged lines down the length of the trunk. These scars will often show vulnerable living wood inside the tree. It’s also common to see scorched or wilted leaves on the side or top of the tree where lightning struck.

White vinegar does not kill ivy on trees because its acetic acid concentration is not high enough to overpower it. Vinegar is an effective herbicide for weeds and other plants, but not for the strength of most ivies, including poison ivy and English ivy. You should use an herbicide to kill ivy, such as one with glyphosate, imazapyr, or triclopyr.

In the case that a tree is growing directly on your property line, the cost of maintaining the tree is shared and is the property of both owners in common. In this case, all decisions regarding the maintenance of the tree must be made jointly, and both parties must agree on a course of action. You will need to agree with your neighbor about the cutting of any roots before you carry it out, and your neighbor must also consult with you before doing any trimming. Coming to an agreement with your neighbor about any shared trees ahead of necessary trimming and maintenance will make this process much simpler.

Stay inside or well away until the storm passes. Don’t go outside to inspect the tree until the weather clears, especially if the tree is on a hill or isolated in a field. Lightning often strikes the same easily-accessed places multiple times, and you could be a new target. If a lightning strike causes a noticeable fire, alert emergency services. When the storm is over, take a closer look to gauge the damage done.
