The Ariana planter waters when you’re not looking and helps keep your plants from drying out. Inside the planter, at the bottom, is a hidden reservoir that holds approx. 1"–3.5" water (depending on planter size). This self-watering insert keeps dirt and roots above the hidden reservoir line while constantly providing healthy “greenhouse-like” moisture through the evaporation process. If you’re forgetful, or you’re just not home very often, Arlmont & Co.'s beautiful Ariana self-watering containers are a must-have! They’re also helpful if you’re growing in an area that’s not convenient to a water spigot, such as a balcony. A great gift idea for a gardener with a busy schedule!
