The day we were in the community garden in Menard, butterflies were everywhere – one sign of a healthy garden.
Our group of Master Gardener students was here specifically to learn about water conservation. In a demonstration, Billy Kniffen pours water into four different plastic boxes on top of a rack. The water then flows down into other boxes on the lower shelf that have drain pipes. The purpose of the demo is to show how much water pours out of the pipe and how quickly it empties out.
What is planted in the ground makes a difference for water absorption. The bin on the left has native prairie grasses growing, which allows the rainfall to soak in, and the long roots of the grasses leads the water further into the ground, replenishing the water table.
Then there is a container that has very little growing in it. Bare ground becomes hard and doesn’t absorb water, which then washes away even more soil.
This shelter and some other small sheds have gutters that direct rainwater into water storage tanks.
The last container has a house. Sponges are placed around the house. Once they have soaked up water, then it will gradually seep out. He suggested having water permeable hard surfaces to prevent water runoff. Replacing concrete with other materials like gravel would help. There are products that have a strong enough surface for walking or even parking a car, but have holes that allow water to pass through. Those have been in use in Europe for many years.
Manufactured permeable blocks that look like concrete are available, but are extremely expensive. Hopefully companies will come up with ways to produce more affordable materials.
Enjoy the butterflies in your garden now before cold weather comes.
