Water your plants every few days with the Kikkerland Automatic Self-Watering Plant Globes. This handy gardening tool slowly releases water into your planter over a period of three to four days. Likewise, they hold 7 ounces of water each, providing enough water for a few days. To use the globes, remove the cork and fill it with clean water. Replace the cork and turn it over to make sure that water comes out of the water release hole. If it does, place the globe in the planter with the cork side facing down. Make sure that the water release hole isn’t blocked in any way. Once you have placed the globes, tap on them a few times to ensure the water is flowing. Made from hand-blown glass, the plant globes are an ideal addition to any home with plants.
