If you live in a small house and have a tiny balcony, have you ever thought about how to better utilize it? Get it well-decorated and become your favorite place? Balcony oasis lets you enjoy the fresh air and sun,
I would've never thought to use river rock at the base of potted plants/at the edges of the patio, but maybe that could work. A larger, flat top rock could even act as a riser for a led candle lantern, etc.
