“Swales” are one of the most common water-harvesting devices used by Permaculturists.
When people see our garden, they often start asking me for gardening advice.
“But master, this is the most beautiful tree I’ve ever seen! How can you not even notice it?”
With 10+ years of experience in observing planned food forests and similar “wild” ecologies, as well as 3 seasons of co-evolving with a home food forest, I’m just starting to form some good conclusions about what makes a really good forest garden in the Great Lakes bioregion. Interestingly, some of those opinions are quite different now than they were a dozen years ago when I first became passionate about the concept of forest gardening.
When first introduced to the concept, here are some of the criteria I would have had for a successful food forest:
–Would focus on productive trees.
–High percentage of the common fruits I liked to eat–a true “fruit forest.”
–Lots of sunny edge for the annual veggies I was used to.
–Focuses on the future potential of a mature forest garden.
–Could produce a large percentage of my dietary needs.
With experience, that hasn’t exactly been changed so much as refined to a more nuanced set of goals. Now, my ideal forest garden would be:
–Appropriately and flexibly yielding. A good forest garden provides things in amounts you can use, when you can use them, without becoming a burden. A really good forest garden is flexible enough that it can be scaled back to produce for a family’s needs without becoming a chore, but could be quickly adapted to provide a yield large enough to provide excess for distribution if needed for friends, trade or income.
–Focusses much more on the understory. This is, afterall, what differentiates an forest garden from a regular “orchard.” At least early on, the understory is capable of providing much more of value than young or middle-aged trees. Think about your diet now, the vast majority of it doesn’t come from trees. When I go foraging in mature woodlands filled with edible canopy species, it is still largely the understory species that I’m there to collect!
–Appropriate and well-planned selection of trees, focussing most on easy, no-spray tree species and support species that provide ecological functions. Right now, on an acre, I’d focus 95% on species that are both very easy to grow without spraying or extra care, and also easy to harvest and use with minimal processing, such as Paw Paw, Persimmon, Honeyberry, Blackberry, Raspberries, Asian pear, Heartnut, Hazelnut, Mulberry, Nanking Cherry, Elderberry, and Hardy Kiwi. I’d also focus on plants that provide greens, such as the Toon Tree, White Mulberry and Linden. Only then would I plant a few more difficult things like apples or plums, focussing only on the easiest and most disease-resistant species. Personally, I’d probably save difficult specimens like dessert apples and green gage plums for green-houses, espaliers or zone1 treatments.
–Lots of sunny edge for a large variety of useful plants, mostly perennials. This would include a lot of high value perennial vegetables, self-sowing annuals, medicinal plants, fiber plants, plants for fuel, plants for crafting materials, etc. Oh, and room for a few high-value annual vegetables.
–Focusses on “succession” and getting an early yield every year.
