...... you also found a way to stop flowers and shrubs from growing or needing watering on business lots...
Well, I said something like this into another thread.
I'm using the TwoJeff's "Perfect Plants" hack and I NEVER have need to garden flowers or shrubs, both into residential, business or community lots.
Flowers and shrubs don't grow-up anymore and don't have need to be watered.
I noticed only an issue.
If a sim waters flowers by himself, THEN I have some "bad-grass" growing up (sorry, I don't know the right word) or a puddle to dry.
