Since I'm new to the game, I don't really know everything so please just tell me if this already exists.
Could we have weed breakouts in our greenhouses/gardens? It would affect the game (by reducing the sunlight your plants take in and increase the size of the weed in doing so) so it wouldn't be a useless thing. C'mon, just for the fun and action! The garden's just a bit boring so maybe just this? Perhaps if we get weeds, it would be an option for the pixie to remove some of the weed from the garden, the outcome would be "as some of the weed disappears, the sun shines through and your plants seem to lean upward."
[sorry, no translation, I'd appreciate it if anyone could do so in my place, thanks! :D]
