The Forest Garden of Agnes Seitz

by Miche Genest

Guild is an old word denoting an association of like-minded people engaged in a common pursuit — armorers, cobblers, or weavers, for example. In Whitehorse weavers, sewers and felters have organized themselves into a Fibres Guild, and theatre-goers attend plays at the Guild Theatre.

On a small homestead on the Annie Lake Road, there’s a different sort of guild at work, involving players of another kind. They are plants; all kinds of plants from herbs to berry bushes to fruit trees, and they work together in a “food forest” planted and maintained by Agnes Seitz and her partner Gertie.

For the past several years Seitz has been slowly building what has become known in permaculture circles as a food forest, but is actually, she says, “comparable to a really extensive home garden.” This kind of home garden has been grown in tropical climates from the Amazon to India for thousands of years; such gardens are a low-intervention way of ensuring food security. In the mid-1980s,

British gardener Robert Hart began experimenting with “forest gardening” in Shropshire, England, bringing those techniques into a more temperate climate. In the Yukon several gardeners and homesteaders are experimenting with building food forests in a much colder environment, Seitz among them.

“The idea is that a young woodland is the most perfect natural system and the most prolific one,” she says. “And that’s what we’re trying to copy, a young woodland.” A young woodland occurring naturally is basically self-sustaining. While a planted food forest is not entirely self-sustaining, it can come close.

Planting in guilds is a cornerstone in the building of a food forest. “You plant in such a way that throughout the season [the plants] support each other,” says Seitz. “There are nitrogen fixers in there, there are attractants that bring in the bees for pollination, there are plants that bring up minerals from the soil. You bring all these players together in a system that makes it so much easier on us.”

When she was starting out, “because we don’t have soil here,” Seitz brought in a truckload of compost from the City of Whitehorse dump. Five or six years later, now that the system is up and running, Seitz’s interventions are low-tech and low-key. She fertilizes with wood ash and human urine. “Humans are one more part of the habitat we are building there,” she says. “An apple tree needs about five pees a year to get all the nitrogen it needs.”

Seitz also uses “green manure,” turning plants into fertilizer using a technique called “chop and drop.” After harvesting, “you just cut the plants and let them fall, and they feed the micro-organisms and that’s how you build the soil.” Seitz also grows a huge annual garden of organic vegetables, which she says requires lots of controls and lots of work.

Square foot for square foot, the annual garden uses nearly twice the mount of fertilizer of the perennial food forest. She estimates there are about 80 species of herbaceous plants in her 4,000 square-foot food forest, most of them edible, like sorrel, burdock, mint, lovage, a wide variety of chives and onions, and Old World plants like sweet cicely and Good King Henry. Mixed amongst these plants are nettles, fireweed, lambs quarters and dandelions. “Wild foods, what we call weeds, are an essential part of the system,” she says.

The next layer up is composed of berry bushes such as Saskatoons, gooseberries, red, white and black currants, haskaps and raspberries. Among the next layer, the fruit trees, are hawthorns, sour cherries, pin cherries, several species of apple, Siberian pear, Manchurian plum, Manchurian apricot, Siberian pine (there may be pine nuts in 12 or 15 years) and even hazelnuts.

The more exotic species are still “kind of a research project,” says Seitz. Though the hazelnuts are not yet fruiting, they have lasted three years. “It’s going to be interesting to see how they did with this really cold winter.” Seitz has not planted low-bush cranberries, a favourite Yukon berry, because she can easily walk into the surrounding boreal forest to find them. “They’re right around the corner.”

But for just about every other kind of herb, plant, berry or tree fruit, she says, all she has to do is walk into her backyard food forest and “kind of like just – forage.” For further reading and resources on food forest gardening, a good place to start is Permaculture Research Institute.
