Many of our guests have been interested in how we practice permaculture on our property. We frequently give tours after breakfast to show how permaculture works and to help guests get an idea of how they can use permaculture principles on their own property to have a more earth-friendly sustainable landscape. We will talk about permaculture swales.
One permaculture element that is readily apparent when entering the property at Cedar House Inn & Yurts is the ditches that seem to be everywhere. Some guests have wondered what are they for? They are permaculture swales.
We began digging our swales several years ago. After strong rains we noted where the rain water travelled on the property and that helped us determine where we should locate our swales.
Why have swales you ask?
Permaculture swales take rainwater that would normally run off the property and send the water into the ditch to be stored for later use. The water in the ditch is slowly released underground after a rain and also helps the mycorrhizal fungi that lives in the soil. Why help the fungi? The fungi attach to the root nodules on the many fruit and berry plants we have planted and help the plants in the uptake of water and soil nutrients.
Our permaculture swales are dug on contour to catch water traveling downhill after the rain. The swales are 1 – 2 feet deep and 1 -2 feet wide. The dirt taken from the ditch is used to make a berm on the lower side of the slope that is used for planting fruit and berries as well as nurse plants. In the future we will talk about nurse plants.
Bottom line is that we think permaculture swales are swell and encourage others to add them to their landscapes. You will have happier soil and plants.

We built a permaculture swale above the vegetable garden and blueberry bush area to capture the rain to prevent runoff and conserve the water for future use. Swales have been proven to retain water by forcing the rainwater into the Earth down to the impervious layer of soil. The water then travels under the surface and provides plant roots with needed irrigation. Such water can travel great distances and be stored for extended periods of time. Swales conserve valuable rainwater that normally runs down slopes and eventually ends up in driveways and storm sewers. They also help reduce evaporation of rainwater.
We built a permaculture swale above the garden to capture water running down the hill from the north end of the property. The swale is approximately one foot deep and 16 inches wide. Swale depth can vary depending on slope of hill and soil type. For example we made the swale shallower but wider in areas with rock closer to the surface which made digging more difficult. The swale at the top of the hill provides water for the peach trees, blueberry bushes and concord grapes. Decomposed leaves are placed in the swale to help retain water. Wheat straw covers the leaves and swale berm to prohibit erosion.
Another smaller permaculture swale was dug at the bottom of the hill using the same technique. This swale catches additional water for the vegetable garden. We are considering the addition of strawberries on the berm portion of this swale since they have deep roots and will help stabilize the berm. Not to mention fresh strawberries in the future.
Additional swales will be built on the property in the future.
Our property at Cedar House Inn is not known for good soil for growing flowers or gardening. We have planted over 250 trees and shrubs since we purchased the property and struggled with digging each hole. First we have a very thin layer of top soil, then hard clay and finally a rock layer. To have a viable garden we have no choice but to haul in or make our own dirt.
Rather than hauling in dump truck loads of top soil I decided to make dirt the way mother nature intended. Down by the yurts we have a forest of trees and layers of leaves under the trees that have accumulated for many years. Raking back some of the leaves you notice decomposition of the organic matter. Worms, insects and fungi are all doing their part in breaking down the leaves. Could I use a similar process to make good dirt in areas where only rock and clay exists? I read about Permaculture (sheet mulching) and Lasagna Gardening that explains just how I can do that.
Last Fall I identified where I wanted the vegetable garden to be. I then took large sheets of cardboard and placed them on the ground as a weed barrier. The cardboard decomposes over time like the layers of leaves in the woods. After watering the cardboard sheets I hauled many loads of leaves to place over the cardboard. Next I added wheat straw, then more leaves. This created a “lasagna like” layer. Some beds were covered with black plastic to help the composting process. When my wife had vegetable scraps I dug a hole in the bed and bury the scraps. I also buried rotted wood to add other microbes and insects to assist in the composting process.
One bed has a worm tower that I made. The tower is a 5 gallon plastic bucket with holes the size of a pencil that I drilled. We add vegetable scraps and red wiggler worms to eat the scraps and make worm castings and tea.
I have read that by Spring if the organic matter is not fully decomposed that is fine. I can dig a hole in the garden for the plant, add some top soil in the hole and plant. This type of gardening also requires no weeding which I like.
We are looking forward to growing vegetables using this simple permaculture gardening method. Be on the look out for more posts about how our garden grows once planting season arrives.
The main problem we have now is that our trees have grown so well that we have too much shade for some vegetables to be productive.
