JUBEL Self-watering plant pot IKEA Will help your plants thrive, even if you can't water regularly. The self-watering insert keeps the soil moist. (Not a fan of the look, but this is a really cool idea)
Useful in gardens, tomato cages are also ripe for repurposing as pretty plant stands. Cut off the spiky feet with a clipper, then spray-paint the cage gold. Set it on its wide end, and fit a pot inside.
