A great way to save money in the garden is to water using collected rainwater. Rainwater is the best choice for both indoor and outdoor plants, it’s pure, unchlorinated and free. You can use rain barrels or other water-collecting containers to collect water from your downspouts. A 1,000-square-foot roof can yield 625 gallons of water from just one inch of rain.
Gardeners Supply offers several rain barrels and downspout diverters to make collecting rainwater easy and efficient, and which will more than pay for themselves over time. A flexible downspout costs $16.95.
