You just moved. Are you planning to move again soon? If not, plenty of time to worry about changing the ground cover and selling the house when you
do plan to move. Meanwhile, "will I be able to sell this house?" is just a toxic mental programming loop implanted to run in your brain by the financial industry, that wants you to think of your home as an investment instead of a place to live. Terminate the program, don't give it mental cycles.
Now, neighbors are another question. Getting along with the neighbors is always better than not getting along with them. But sometimes, it can't be done.
First of all, do they have leverage? Is there zoning, homeowners association rules, or other legal stuff they can pull on you to command you to obey them? You need to know
the answer to that question with certainty.
Assume there's none of that and you can do as you wish. Still, you don't want bad relationships. Can you still talk to the traditional neighbor
enough to find out what their core concern is? Are they just trying to command you to conform to their notion of what the neighborhood
should look like because they hate non-conformity (in which case, nothing you do short of obeying them will placate them) or do they have specific concerns about specific (negative from their perspective) impacts on their property (
bees flying over to visit, clover spreading to their lawn, et cetera)?
If they have specific concerns and are willing to talk them out with you, it's worth talking them through and seeing if you can offer something. "I'll build a
fence, I'll build a hedge so you don't have to see, I'll mow a strip and keep it in grass twelve feet along your property line," whatever. Happy neighbors are a joy; hateful neighbors are a curse. It's worth a LOT of compromise to have the former instead of the latter. But the kind of neighbors who insist that you obey all their commands about how to keep your property never wind up happy anyway; they always have more commands. So there's no point in trying to placate them. If they won't talk and reach a compromise that they agree to be happy about,
fuck 'em. Grow your clover to the sky! Well, that's what I would do.
