I was recently introduced to the olla – a back garden hack which is been used for hundreds of years to assistance irrigate gardens. What is an olla, you could ask? Properly, it really is a basic terracotta vessel which is buried in the ground alongside your vegetation and crammed with drinking water. 

The h2o is drawn through the terracotta when the soil encompassing it is dry, helping to retain your vegetation from ever heading thirsty, although also not overwatering. Due to the fact it really is underground, it would not evaporate in intense heat and sunlight, much too. Appears wonderful, correct? Perfectly there is certainly one particular significant downside.
