Lasagna Gardening (It's Not What You Might Think)


Lasagna Gardening (It's Not What You Might Think)

Since ancient time people have known that land can become worn out from too much farming. The ancient Hebrews would let the land lie fallow every seventh year, during which time it undoubtedly collected new topsoil that had been depleted from six years of growing crops. The Dust Bowl of the 1930's was partly caused by ploughing the land. Small, loose particles of dirt blew from the Middle West all the way to the Atlantic Ocean. Much of Australia is desert, and irrigation can be expensive. Farmers there invented a technique, called lasagna gardening, designed to conserve water, and a native Californian working in Australia brought the technique to his home state, where it has taken hold.
Lasagna gardening does not involve planting lasagna seeds to harvest a pasta dish. The name comes from layers that are used to build up the soil rather than disrupting it. Besides helping to conserve water, the technique builds up organic matter and produces a soft soil where roots can grow. To build up your soil the first thing you will need is newspapers. Save only actual newspaper with its rough texture. Do not include glossy Sunday supplements or advertisements which will add unwanted chemicals to your soil. Colored photographs on newsprint are okay. A 6 month’s supply of newspapers will cover about 600 square feet of ground.
The next thing you will need is hay. Alfalfa hay has a sweet scent and a lovely spring green color, but feel free to experiment with different kinds. Hay is available at feed and grain stores. Two bales should cover a 600 foot garden.  You can make life easier if you buy bales that have been sliced like bread. Lastly, you will need compost. If you are just getting started it is not considered cheating to buy compost or gardening soil at the local home improvement store.
Begin by finding a sunny location far from any trees. Trees hog all the sunlight, soil nutrients, and water. Most vegetable plants need plenty of sun to convert into the energy that goes into growing and making food. When you have found a good spot, begin by covering it with newspapers, at least 2 inches in thickness. The newspapers are there to hold in water, so pile them high. (Don't try this step on a windy day). Next, separate your hay slices and place them like paving stones over your newspaper layer. Spread your compost or garden soil evenly over your hay, taking care to disturb the hay as little as possible. If the hay and compost get mixed together, just shovel on some more compost to make a nice, thick top layer, at least 2 inches thick. 
Now your lasagna soil is ready for sewing seeds. Sow them in the compost layer at the depth specified on the package. Your new soil will gradually settle, get worn down by the elements, and become depleted from your crop. It is recommended to renew all your layers each spring. Happy growing!
