It'd be cool if we could clear spawns permanently. A couple of sprigs keep popping up in my base, I trash them every time, but they're always there!! I can't put in a foundation due to the "obstructions" around so I'm stuck with these sprigs unless I want to move my whole base up to accommodate foundations.

I’ve noticed players are posting about issues with both things spawning when they shouldn’t according to the rules we know and not spawning back when they should. (I have the latter problem)
 

I don’t know what’s causing the glitch, but I think it would be neat to have both a fertilizer and a weed killer so we can reactivate spawning for a grass stems and weeds where we want to and deactivate where we want to.
