Can my plant grow on top of a rock?

A 10 inch hole in the dirt should be sufficient to sustain your plant. Just make sure you water and feed the plant as suggested.

@silverfly: I don’t know if you need to remove the rock for your plant but I always remove the rocks I hit while digging as a policy. I feel that it is a sort of land improvement.

I don’t know if I can remove it though. It seemed pretty big. Ideally, that’s what I would have done.

It should be fine. This is what plants encounter in nature, and the roots will go around it. If the soil is enclosed on the sides as well, or if it is competing on the sides with other plants root systems it could be a problem, but otherwise not.

@silverfly: I do not know how rural a setting you are in but to me this sounds like as good a reason to get a dynamite permit as any. Do you have kids, drinking buddies? What would they think if they knew you had a perfectly good excuse to use dynamite and blew it?

@malevolentbutticklish I live in the city and the plant is right against the neighbors fence. Somehow, I think dynamite might be a problem. :) Does sound fun though.

If you take the longer view that Earth itself is “a rock”, and look at how well we’re all growing (some of us grow “out” more than “up and down”), then I guess the answer should be obvious.

I doubt it will be a problem. They can grow in containers without any problem. Give it the proper amount of water and plant food, and it will do find. The roots will work their way around the available soil.
