8. Glass Bottle Propagation Stations
Propagation is a rewarding way to multiply your houseplant collection for free. Turn old glass olive oil bottles, wine bottles, or decorative jars into modern propagation stations. Build a simple wooden rack with circular holes cut using a hole-saw attachment to hold the glass vessels securely in an upright position. Fill them with water and snip off stems of pothos, philodendron, or tradescantia to watch roots develop in style.
