Robert Kourik on Drip Irrigation March 3, 2014 interview
We interviewed author and edible landscaper Robert Kourik about an upcoming talk on drip irrigation as a way to deal with less available water. His Drip Irrigation For Every Landscape and All Climates, and Roots Demystified, taken together yield the following pearl: Deep roots help a plant survive, shallow feeding roots help it thrive. In order for thriving to occur, best to run drip irrigation for a short time every day so the shallow feeding roots stay moist (like a wrung-out sponge). Infrequent deep watering wastes water, putting it below the feeding roots, and hits the soil biology with floods and doughts so it tends to die off. To get a copy of any of his books (Designing and Maintaining Your Edible Landscape - Naturally is a 1986 classic) and check out his blog posts, there is a site robertkourik.com.

His favorite source of drip irrigation supplies is a local Willits business which also ships, Dripworks. This is not an endorsement.
