“Here is the incredible thing about God and His design, when there is too much water the wood chips displace it and when there is not enough, the wood chips retain it.” - Paul Gautschi
Water as needed. Watering is only necessary if the compost below the wood chips is dry to the touch.
Tip: Set up your own drip irrigation below the mulch for plant rows. Sub-irrigation is when plants are watered from below the soil to reduce evaporation.
