I was recently introduced to the olla – a garden hack that's been used for centuries to help irrigate gardens. What is an olla, you may ask? Well, it's a simple terracotta vessel that's buried in the ground alongside your plants and filled with water.
The water is drawn through the terracotta when the soil surrounding it is dry, helping to keep your plants from ever going thirsty, while also not overwatering. Because it's underground, it won't evaporate in intense heat and sunlight, too. Sounds great, right? Well there's one major drawback.
