Disadvantages of an Olla Pot Watering System
- Takes time to dig and install the pots, however all the best watering systems do
- Takes up space in the soil that could be used for plants
- May need to be removed for maintenance, such as being scrubbed with a 1:1 ratio of water vinegar solution 2
- Does not work for trees, shrubs and plants with woody roots that can pierce and destroy the clay pot walls
- Hard to know the water level of the pots, however you can use moisture sensors to help
