The URI CE Master Gardener Demonstration Vegetable Garden, July 2004

What you will see!

The following page highlights water conservation practices that were demonstrated during the healthy landscapes education program.

The healthy landscapes education program provided materials for the installation of a demonstration rain barrel.

URI Master Gardeners installed a drip irrigation system in July 2004 to water a demonstration vegetable garden. Additional examples of drip irrigation can also be viewed at URI East Farm.

View our healthy landscapes factsheet water wisely for more information on water conservation in the home landscape.

This ready-made rain barrel can hold 54 gallons of water.

This rain barrel is set on blocks to provide additional height for gravity flow. The roof gutter downspout was retrofitted to outlet about two inches above the rain barrel's screened opening.

URI Master Gardener Dick Perreault installs a new drip irrigation system in the Garden. July 2004.

This newly installed riser includes the mainline (1), a timer control unit (2), the filter (3), and pressure regulator (4). Other essential components of a drip irrigation system include the valve and backflow preventer, which are located at the main water supply in the Demonstration Vegetable Garden, and the drip tubing with emitters.

Newly installed drip tubing in the Vegetable Demonstration Garden. The straw shown in these pictures is used as mulch to retain moisture and reduce weed growth.

This is the timer used to automatically control the drip irrigation system in the garden. Drip irrigation can be set to run automatically, like sprinklers, or it can be controlled manually. Manual operation allows you to take advantage of rainfall before applying unnecessary water.

The red dot in the picture above is the emitter where water is released into the root zone of plants from the drip tubing. Emitters should be checked regularly to ensure they are flowing and not clogged.

This is an end cap which prevents water from running out the end of the drip tubing.

Drip tubing should be staked down to keep it from moving. If the tubing moves, it may no longer be targeting the root zone of the plants.
