I've always enjoyed more options, but simply having some options hinder you severely.
Was thinking it would be cool if you 'could' plant on grass (without plowing) but there would be downsides to it, slower growing times, chance that the plant doesn't reach final growth (grows to stage 2-3 and then just dies [has to be manually removed]).
Would be funny for people who are rushing to fuck up and then have to wait 6+ hours just to see if now they're one short, but won't hurt people who continue to do it properly.
Just an idea to toss out there.
