The Add-A-Bottle Watering Spike makes it possible to water less often – great for vacation care, or pots in sunny places. Simply attach your own regular screw-type bottle (up to a half-gallon in size) to the Watering Spike insert and slide the insert into the spike; the bottle acts as a water reservoir.
The Add-A-Bottle Watering Spike measures 5” long and tapers to a sharp point allowing you to insert the spike into existing planted pots with ease. Once the reservoir bottle is empty, simply lift the insert out of the stake and refill. The Watering Spike stays in the soil. Plant roots will grow around the Watering Spike and use water more efficiently. Sold in sets of 4.
