We’ve been planting trees in the field around the access:energy workshop. Four moringa (moringa arborea) and a mango tree. To save us having to water the plants each day, my colleague Caleb suggested we use glass bottles to do it for us.
After digging a small hole next to the plant, you fill it with water. Ensure the glass bottle, is fully filled with water, then tip it upside down and press it into the hole, pointing towards the plant. Water will be absorbed from the bottle as the soil and roots need it, so you only have to visit your plants every few days. It’s basically a low-tech drip irrigation. We are hoping the moringa trees will shoot up fast now. Apparently they can reach a height of 3 meters in a year.
