Scheurich has created this plant water reserve so that you no longer have to worry about your plants getting watered while you travel. When you fill the reserve with water and stick it into the soil of your plant it will slowly disperse the water into the soil. This medium sized water reserve designed in the shape of an orange bird, will water your plants for up to 4 days. So get a Bordy and take the worrying out of your next trip! Colors: Orange, Green, Blue & Clear, so please specify the color you would like.
