Transformation from Ailanthus to Food Forest

From Invasive Ailanthus Grove to Food Forest

The rear of the property is a daunting invasive Ailanthus grove on a steep slope. After removing the invasive species, the space gives way to a sunny slope appropriate for a food forest. It is comprised of Paw paw, Asian persimmon, Cherry and Peach. Companion plants include Indigobush, False Blue Indigo, Pink Turtlehead, Butterfly Milkweed and Anise Hyssop.

The front yard is full of edible natives like American Hazelnut, Blueberry, Elderberry and Currant paired with ornamental natives like Dogwood, Redbud, Bayberry, Echinacea, Asters and Virginia Bluebells.

 

Rainwater Collection Using the Earth, Not Rain Barrels

Rainwater Collection Using the Earth, Not Rain Barrels

By Danylo Kosovych and Organic Edible Gardens LLC

When it comes to rainwater collection the first thing people think about are rain barrels but you don’t need a barrel to collect rain water. Rain barrels are useful if you want to store water and use it for irrigation but for storm water management they are dwarfed by amount of rainfall that falls in the average storm. Once inch of rain falling over a 1000 square foot roof produces 600 gallons of water. A 50 gallon rain barrel only catches 1/12 of the water. A 600 gallon water tank is not only large and obtrusive but also expensive.

Not to worry, rainwater collection can be achieved in multiple ways without using a container at all. Below are examples of multiple ways we have collected rainwater using the earth as the container.

You can catch rain water in a swale:

A swale is a depression in the earth, dug on contour and linear in shape, therefore adept at catching runoff. This client had runoff problems from their neighbor. We created a swale along the property line to catch and infiltrate the runoff before it entered their property. The Elderberries and Aronia benefit from the additional water.

You can catch rain water in a rain garden:

A rain garden is a bowl shaped depression that works well to catch stormwater from a downspout. We later planted this one with Aronia, Low- Bush Blueberries and native perennial flowers. The soil in the center is deeply tilled and the water infiltrates rapidly, while the plants benefit from the additional water.

Or you can use perforated pipe to leach rain water into the soil:

This is a vegetable garden which we created on contour and directed the roof runoff into a perforated pipe and buried the pipe in gravel. All of the water from the roof infiltrates into the soil and waters the vegetable beds.

Here we used the same principal with the infiltration pipe but planted columnar apple trees on top of the pipe. Now the water from the roof irrigates the apple trees.

Alpine Strawberry

 

Ecology

Fragaria vesca ssp. alpina, or alpine strawberry, is a prostrate fruiting herb that has been eaten by humans since the Paleolithic.  Like a great many of our favorite cultivated plants (apples, pears, roses, plums, peaches, etc.), it is a member of the Rosaceae, or rose family.  Alpine strawberry is a subspecies, or distinct strain, of the wood strawberry (Fragaria vesca) which is native to most parts of the Northern hemisphere.  Alpine strawberries in particular come from the European Alps, where they have been esteemed for centuries – often depicted in medieval tapestries.  Unlike other strawberries, alpines do not send out runners, instead remaining as a single clump.  While other strawberries yield large numbers of fruits at a single time of the season, the alpine strawberry fruits all season long, albeit in smaller numbers.  It is a woodland plant, preferring moist soil and dappled or part shade – plants will fruit with as little as 4 hours of sunlight.

In the garden

The non-spreading habit of alpine strawberries makes them excellent for use on the edges of borders.  The leaves are evergreen, which helps avoid the “dead” look of many winter gardens.  They are also very suitable for part shade, that being both a characteristic of most gardens in our region and of the alpine strawberry’s native habitat.  The fruits are incredibly delicious:  Edible Forest Gardens author Dave Jacke says, “…there is more strawberry flavor packed into one of these tiny fruits than in any number of enormous store-bought hybrids!”   There are a number of cultivated varieties – one of my favorites is ‘Pineapple Crush’ – a nearly white colored strawberry with a hint of pineapple flavor, and the white color decreases the chance that birds will get the berries before I do!  Alpines are also incredibly easy to start from seed, and grow fast – seeds started in the early spring will bear a small crop that season, and larger crops in successive years.  Overall, alpine strawberries are a great, long-lived, low-maintenance perennial with superior fruit that can add much to any garden or edible landscape.

Species Profile: Sea Buckthorn

Posted on by

For a while now, we’ve wanted to start profiling certain plant species here on our site.  There are a few reasons for this:  First, a lot of these plants are unfamiliar to American gardeners (outside of  some permaculture circles, that is!), and they definitely deserve a bit more popularity for several reasons.  Second, we want to show that functional plants (edible, medicinal, etc.) can serve very powerful aesthetic purposes in the landscape as well.  We hope that you will enjoy these profiles as we post them, and that you gain an appreciation of these amazing plants!

 

Sea Buckthorn

 

Sea Buckthorn (Hippophae rhamnoides) is a large shrub in the Elaeagnaceae family that is native to Europe and Asia – it can be found from Britain to Japan, Norway to the Himalayas.  In the wild, Sea Buckthorn is typically found near the coast (hence the ‘Sea’ in its common name), growing out of cliffs and sand dunes.  What is interesting is that by evolving to grow in these harsh conditions (sandy alkaline soils, exposure to salt, etc.), it basically has the ability to grow in nearly any soil and any conditions you can throw at it (wet, dry, near roads where they put down salt in the winter, etc.), which is great for gardeners in many different kinds of growing areas.

 

Sea Buckthorn

 

One of the reasons that Sea Buckthorn can survive in so many different kinds of conditions is that it, like other members of the Elaeagnaceae family, is what is called a nitrogen fixer.  Basically, this plant forms associations with soil microorganisms (in this case, a genus of actinomycetes called Frankia) .  The plant absorbs atmospheric nitrogen, which is not readily used by plants, and transfers it to its roots, where it is “processed” by the microorganisms (in exchange for plant sugars and nutrients) into a form of nitrogen which IS available for uptake by plant roots.  What this means, is that the plant provides its own fertilizer.  This fertilizer is available for use by other plants, too – when its roots die back (which happens naturally or can be encouraged by coppicing, as described below), or when it drops its leaves in the fall, the nitrogen concentrated in these tissues remains in the soil, available for uptake by any nearby plant.  Having these nitrogen fixing plants in the garden can reduce or eliminate the need for external inputs of nitrogen and other elements commonly found in fertilizers.

Aside from providing a good amount of fertility to the garden, Sea Buckthorn can serve many other functions in the garden.  It makes a great hedge for keeping out unwanted intruders (human, deer or otherwise) – it does have thorns, so avoid placing near paths or where children play.  It is a very beautiful plant – silvery gray-green, almost needle-like foliage gives it a very Mediterranean-like appearance.  When it bears fruit in the fall, the plant is literally COVERED with brilliant orange berries – very much like Winterberry (Ilex verticillata), a common shrub in eastern American gardens.  We’ll talk more about the fruit below.  Sea Buckthorn can get to be 10-20 feet tall if left to its own devices, but can be kept reasonably small by coppicing (cutting it to just above ground level in the winter when it has gone dormant) every few years.  It is an excellent plant for holding together soil and preventing erosion.

Sea Buckthorn fruit is not very good fresh – the berries are very tart and astringent, but they make an incredible juice when steamed or pressed and then sweetened.  They are incredibly nutritious, too – incredibly high in Vitamin C and Vitamin A, antioxidants, and healthy fatty acids.  Jams, jellies and wines made from Sea Buckthorn are delicious.  The fruit yields an edible oil which can be used for cooking, and is also used to make an inexpensive and easily produced biodiesel fuel.  Other uses of the plant include medicines, cosmetics, charcoal, wood fuel, and yellow dye.

To conclude, Sea Buckthorn is an incredibly beautiful, useful, multifunctional plant that we think deserves more of a place in our gardens and landscapes.  Stay tuned for more useful plant species profiles, there’s a whole world to cover!
