Easy ways to get rid of weeds and stumps

Easy ways to get rid of weeds and stumps

Is there a natural/safe version of Round-Up? Something that can be sprayed on weeds in hard-to-dig places, or weeds that have roots going down to the center of the earth (dandelions, for example)? I don't want to poison the entire world, but I'm okay with poisoning a few localized weeds. Also, is there a natural/safe way to get rid of stumps? I'm thinking I've heard of something that might make stumps decompose over a relatively short amount of time, but I'm not sure what that would be or if it's reasonably safe to use. PS: thanks for the advice on the baaaaby trees...they're currently in buckets, getting frequent watering.
