They keep the right amount of moisture that is needed for your plant’s soil for a few days. No more daily watering or plants drying out while away on vacation for a few days.To Use Watering Bulbs:
1. Fill the bulb with water
2. Insert stopper
3. Simply insert the stem of the bulb into the soil at an angle.
3. Let the self irrigation system begin
