Weeds and Water

When does a plant become a weed? What’s the best way to water your garden?

Learn to identify, prevent, and control common garden weeds such as chickweed, purslane, plantain, groundsel, pigweed, willow herb, lambsquarters, dead nettles, stinging nettles, dandelion, yellow wood sorrel, quack grass, reed canary grass, field bindweed, creeping buttercup, and dock.

Discover the best way to water your garden during our dry summers. Designing an irrigation system can be daunting, but this class will help you understand the drawbacks of overhead watering and how, instead, to use flow restrictors, manifolds, timers, soakers, connectors, and various types of emitters.

Below are resources to enhance your learning.
