Keep your plants watered with this practical terracotta olla spike irrigation system. Designed to gradually release water into the surrounding soil, it is ideal for helping to keep your plants hydrated with less frequent watering.
Simply fill the olla with water, secure the removable cork lid and place the spike into the soil. With a generous 540ml capacity, it can hold enough water to last over a week in a standard planter, depending on conditions and the water requirements of the plant.
