1. MICRO-IRRIGATION FOR SCHOOL GARDENS

2. WHAT YOU WILL LEARN TODAY Benefits of using micro-irrigation in your school garden Types of micro-irrigation Maintenance requirements of a micro-irrigation system How to assemble a micro-irrigation system with a hands-on demonstration Free stuff!

3. WHAT IS MICRO-IRRIGATION? Carries water to plants under low pressure (30 gph or less) Can install micro-irrigation above, on or below the surface of the soil Inexpensive compared to many types of irrigation systems and you can retrofit many systems to accommodate micro-irrigation

4. WHY USE MICRO-IRRIGATION IN EDIBLE GARDENS? Will reduce water use—save money, conserve water! It has been shown that micro-irrigation is 90% efficient vs. 50-70% efficiency of traditional sprinkler systems Can reduce disease problems as foliage stays dry Can reduce weeds as rows are not watered Easy to install Requires little water pressure to run Can easily automate with a battery-operated timer Easy to use in odd-shaped gardens

5. WHY USE MICRO-IRRIGATION IN EDIBLE GARDENS? Unrestricted by watering codes Be mindful to water only as needed and never in the middle of the day! Easy to expand and adapt over time Flexibility to meeting varying water needs

6. TYPES OF MICRO-IRRIGATION In-line dripDrip emitterMicro-sprayer Bubbler

7. DRIP EMITTERS Used where plants are spaced farther apart or used for potted plants and hanging baskets. The emitters can be punched directly into the "header" tubing-and/or attached to "spaghetti tubes" that lead to plants.

9. IN-LINE DRIP TUBING Placed on or below the soil surface or mulch, drip tubing is ideal for vegetable gardens where plants are in rows. The flexible tubing can also be easily wound through a plant bed.

11. BUBBLERS Installed on short stakes or directly on distribution tubing. Usually water 180 or 360 degree with an adjustable flow. Use bubblers to establish or maintain larger plant material.

13. MICRO SPRAYERS Used just above the surface, micro-sprayers wet a larger portion of the ground and emit more water than other types of micro- irrigation systems.

17. WATERING YOUR EDIBLE GARDENS Connecting micro-irrigation to existing system or underground pipes Simple to transition Underground lines in place Need to attach a new valve for micro-irrigation Conversion kits available

18. LAYOUT

22. MAINTAINING A MICRO-IRRIGATION SYSTEM Frequent inspection is key! Check for signs of dry/wet soil or decline in plant health It can be difficult to tell if a drip emitter or in-line drip system is clogged If a micro-sprayer is not working, you may have a clogged filter Parts can easily be damaged by mowing and maintenance equipment
