Creating DIY ollas is a wonderful way to enhance your garden's irrigation while embracing a sustainable approach. An olla is an ancient terracotta pot, traditionally buried in the soil, that slowly releases moisture to the surrounding plants. To make your own olla, you will need a couple of unglazed terracotta pots – one larger than the other. Start by taking the smaller pot and drilling a few holes in the bottom. Then, place it upside down inside the larger pot, positioning it so that they fit together snugly. Fill the larger pot with soil and plant your favourite vegetables or herbs around it. When you water the olla, the liquid will seep through the porous terracotta, providing a consistent moisture supply directly to the roots. Not only does this method conserve water, but it also saves you time on frequent watering, making it a charmingly practical addition to your garden.
