It’s not legal to intentionally damage a neighbor’s tree. Even if the roots of a tree encroach into your yard, if you damage or kill a tree that belongs to your neighbor, you can be held liable for the damage in most cases. Since herbicides can spread through the tree, causing damage to the whole tree and not just the roots that are on your side of the property line, you shouldn’t poison your neighbor’s tree. The other downside to this method is that if the tree dies, it can fall onto your property and cause more damage, so herbicides are best avoided in this circumstance.

Technically, dandelions aren’t bad for your lawn, and they don’t directly kill grass. In fact, they appear in areas that are nutrient-deprived, and their long taproots can loosen the soil and bring nutrients closer to the surface. 

However, dandelions do spread quickly, and they can take over your lawn, eventually crowding out grass. This is why a healthy lawn is the best defense against dandelions.

There are organic herbicide options that will kill grass but not flowers, including white vinegar or a dish soap solution. Commercial selective herbicides can also target grass over other plants, but read the instructions carefully to avoid damaging your garden. Herbicides that kill grass but not flowers usually include ingredients like clethodim and sethoxydim. Otherwise, your best bet will be to weed by hand.

Sealing pavers helps cut down on weed growth, but it won’t wipe it out entirely. What it does really well is harden the joint sand—especially if you’re using a sealant with polymer additives—so weeds have a much harder time breaking through. It also blocks airborne seeds from settling in the cracks and keeps debris from building up. This results in fewer weeds, easier maintenance, and a cleaner-looking surface. Just remember, sealing is a strong defense—not a one-and-done solution. Stay on top of sweeping, spot-treating, and resealing every few years to keep your weeds in check.
