Plant Pal Watering, set of 4
Reuse your glass bottles
These self-watering stakes help keep your plant consistently watered, so you don't need to worry about over or under watering. They work with any standard wine bottle and most longneck glass bottles.
Just place the stake into moist soil. Fill the bottle with water, then place onto the stake. Water is released into the soil slowly as it begins to dry, keeping the soil continuously moist. See at a glance when to re-water and refill as needed. For larger plants you may want to use 2 stakes. Comes in a set of 4.
