The Desert Oasis Teaching Gardens

Feb 2018 The Desert Oasis Teaching Garden

Started in Fall 2013

2 acres of gardens

We are an experiential learning space

We are a school AND community program!

We grow bounty in the desert

Climate Change in the Desert

We know that

Groundwater is being over-pumped, wetlands are drying out, lakes are shrinking, and large rivers are so tapped out that they rarely reach the sea.

Climate-warming trends over the past century are due to human activity.

Really good news – each of us can help

A 2% increase in the carbon content of the planet’s soils could offset 100% of all greenhouse gas emissions going into the atmosphere

So, no matter…

what size your garden is

or what shape…

We can all create Regenerative Systems

By growing organically & sustainably, we are:

Regenerating soil health & saving water

Restoring our health

Fostering wellness for the whole planet

Innovations + Traditions

To be “water wise” – think about:

SoilSun

Water Seeds/PlantsAmendments

Challenges for growing here

• Too sunny

• Too hot

• Too windy

• Low rain

• Low humidity

= Evapotranspiration deficit

Our soil quality is variable

What’s your Soil Type?

What makes great soil?

Organic Matter

How does soil capture carbon?

This is why Soil Carbon Matters!

Healthy soil captures carbon & holds more water!

Where to use Ollas

How do Ollas work?

MicroSprayers

Swales and Berms

A swale is a shallow trench dug along the land’s contour, with a berm on the downhill side.

Swales and Berms

1” of rainfall x 1000 sq ft = 620 gallons

Soil Sponges

Water Trees at the Drip Line

WaterSmart review at DOT Gardens• Collect rainwater:

• Soil sponges

• Swales

• Cisterns

• Use drip irrigation

• Try Ollas

• Grow in a sunken bed

• Use shade structures
