Use your recycled 2-litre bottles with Self Watering Cones to keep your plants and flowers watered. Aqua Cones work with any soil type because they were designed with punch-out holes near the top for sandy soil, near the middle for loam, and near the bottom for heavy soils.
The Self Watering Cones collects rain and stores it so that it can provide continuing water to your thirsty plants.
