My damn problem is invasives.
We used to have an all native yard. But as my disability has gotten worse, maintaining that state has gotten prohibitive. Then that fucking hurricane messed things up, and it's pretty much wrecked in the terms of native plantings now.
Don't get me wrong, it's actually really pretty, all wild and green. But trying to get rid of stuff like kudzu is not an easy task, and it isn't the only thing that's taken advantage.
