Rain Barrels and Wicking Gardens

Rain Barrels: This class is sure to be a barrel of fun!  Experts agree rainwater is the best water for your lawn, landscape, or vegetable garden.  Join us to learn simple techniques on how to divert, store, and use one of nature’s best resources for the garden.  We’ll also pour through the basics and benefits of rainwater harvesting in barrels and how it can reduce the effect your stormwater has on the environment.  We’ll discuss how you can build your own rain barrel, rather than purchasing a pre-made (or ready-to-assemble) version, with some basic supplies and a few simple steps.  

Wicking Gardens:  Wicking beds and pots water themselves and are a great DIY project for the water smart gardener.  Wicking beds and pots are watered from a reservoir below the soil.  Through a practical demonstration, this workshop will introduce the principals involved and give you the know-how to build a wicking garden system at home.  A wicking bed prototype will be explained as part of the workshop.  

Participants will learn:

An introduction to the benefits of wicking beds and pots, and how they work
Different types of wicking beds and pots
Tips and traps in making your own
Practical demonstration

Water Conservation Series

This session is part of the Water Conservation Series. These workshops were developed in response to common questions and concerns about various topics related to water conservation, water quality, pollution increases, and ecological issues.  The workshops provide a brief overview (with a chance for questions and answers) for Texas Hill Country residents to better understand where our water comes from and how to protect this important resource. The 10 sessions in this weekly series take place on Mondays from 12:00pm to 1:30pm beginning June 5th and ending August 7th. Feel free to bring your lunch while you learn of ways we all can protect our precious water sources!
