What most people consider pruning is taking a power tool to the exterior of a shrub and turning it into a perfect ball, or hedge row. While this tactic applies to hedges it does not benefit most shrubs and trees. A common pruning practice that you will see when it comes to trees is chopping off the top of crape myrtles. The crape myrtle will survive and flower a lot the next year but the aesthetic structure of the tree is lost forever and will have to be pruned in the same manner every year thereafter.
A much more practical way of pruning which enhances the aesthetic structure of the tree while aiding in pest and disease resistance and increases fruiting (in fruit trees), is pruning from the inside out. This process is called thinning.
The primary objective of thinning is structural; open up the canopy for air and light penetration. Allowing more air to flow in the center of a tree or shrub canopy reduces disease by allowing limbs and leaves to dry sooner. Increasing sunlight onto the interior buds of a tree increases fruit production. Shaded branches are unproductive but they still use nutritional resources.
During the winter, woody plants store their energy in their trunks and roots. Branches have little stored energy and can be removed without altering the stored energy of the tree or shrub. Because of their dormant state large portions of trees and shrubs can be removed. Plants heal best in the spring and summer, when their physiological processes are at their peak. Wounds from fresh cuts are prone to winter injury, therefore late winter is best. Plants can also be pruned in the summer but major limb removal should be kept to a minimum because you will be reducing the energy of the plant. If the plant is spring flowering and the pruning needs minimal you can wait until after flowering.
The best way to prune a tree or shrub is by looking at the plant from the inside out. Before you cut anything, analyze the plant. Find the large branches that reach the canopy. They should come out of the trunk at an almost perpendicular angle. These are the main structural branches. Do not remove these. Start by removing dead, diseased or broken branches. Any small branch that starts within the interior and does not make it to the canopy can be removed. They are shaded and unproductive. Remove any branches that come out of the truck with a very small crotch angle and then grow vertically through the canopy. They are shoots. They will be of smaller size than the main structural branches and entangled through the entire canopy. When making a cut it is best to remove an entire branch from the trunk at the end of the branch collar.
The resulting tree or shrub will have a cleaner look. There will be less small limbs in the interior of the canopy making the larger structural branches more visible. It will also be more resilient and require less ongoing maintenance as plants pruned from the top down.

The shortest day of the year in the northern hemisphere is December 21st , the winter solstice. From the advent of the solar calendar, cultures have been holding celebrations on this day in association with their religious beliefs. At this time of the year all of the season’s agricultural work would have been finished and the days were dark and cold. People were indoors and free of the bulk of their chores. If you make your living as a landscaper like I do then the agricultural ebb and flow of the seasons still largely applies. In reference to the suburban garden, the plants are in dormancy and the ground is frozen, now is a good time to rest, relax and reflect.
While snow will have to be removed from paved surfaces like the driveway, walkways and streets, it can be left alone on planted surfaces. Plants with marginal cold hardiness should have been mulched and protected from frost before the onset of winter. Late winter is the best time of the year for dormant pruning but not until February or March. The year’s gardening work is finished. Take some time off.
Many companies have realized that giving their employees time off of work can actually increase productivity and quality of work when their employees return. This is especially true in reference to creativity. Progressive companies like Google are known to give employees an entire month off in an effort to boost creativity. As a result of this policy they have produced some of their most creative innovations. Removing yourself from direct mental and physical engagement with your work allows you to return to your work refreshed and with a new perspective. Simply being able to rest and refresh the mind and body will lead to improved results when one returns. A change of scenery and a break from the ordinary routine can produce insights previously not thought of.
If you kept records of your garden now is a good time to look them over and think about the next year. Walk the garden in winter and take note of the structure of trees and shrubs as they are bare of leaves. Pay attention to the garden beds and pathways, their layout is easier to see without all the vegetative growth of the summer. But most importantly take a load off. Read a book next to the fire. Go on vacation. Meet with family and friends. Drink, eat and be Merry!
Fallen Leaves: A Valuable Resource, Not a Waste Product
©2013 Danylo Kosovych and Organic Edible Gardens LLC
One of the first practices that struck me as odd when I began landscaping is the collection and disposal of the season’s fallen leaves. Leaves are a good source of organic matter and plant nutrients. You can reduce your mulch and fertilizer inputs by using what nature provided, rather than paying money or expending energy to get rid of them. If you live in a forest you can simply let them lie but like most people who have a combination of lawn, garden beds and paved surfaces the leaves will need to be processed in one of three ways.
Deciduous trees drop their leaves each fall storing all their energy within their roots. In mature forests the leaves fall onto the ground and whatever nutrients remain are cycled back into the system. Trees need leaf litter; it keeps the soil warm in the winter and prevents evaporation in the summer. Just as we put on more clothes in the winter to keep ourselves warm. Leaves create a warm blanket on the ground, their active decomposition creates heat. The litter of fallen leaves under the tree creates an ideal substrate for beneficial soil fungi and bacteria to grow in. The metabolic activity from these microorganisms can keep the temperature higher than in the surrounding area. The increased warmth supports microorganism activity and root growth as well as providing a habitat for insects and small animals.
The large area and number of trees in the forest keep the leaves on the forest floor. Landscape beds are much smaller and many times slightly raised in comparison to walkways and lawns. As a result, fallen leaves tend to blow off of landscape beds and collect in lower areas of the property. Shredding the leaves reduces the surface area that catches the wind, keeping them in place. They also tend to mat less, preventing the smothering of groundcovers. Shredded leaves have a more uniform color than whole leaves. Leaf mulch is an attractive dark brown and slowly decomposes, releasing nutrients to the plants, and preventing winter damage by keeping roots warm.
Shredded leaves in garden beds:
An even easier way to utilize fallen leaves is to shred them into your lawn. This takes only slightly more work than mowing your lawn. You will have to mow your lawn 2-3 times over to get all of the last leaves. All it requires is a mulching blade and closing the discharge chute. A study by Michigan State University, found that mulched oak and maple leaves reduced the amount of dandelions and increased spring green up in lawns. They reduce the prevalence of dandelions by reducing dandelion seed germination. Shredded leaves provide nutrients and organic matter to the lawn producing a thicker, greener more drought tolerant lawn.
Fallen leaves contain a small percentage of nutrients, ranging from 1-3% nitrogen, (the higher being from leguminous trees) and small amounts of phosphorous and potassium. While the percentages might be small, the sheer volume of leaves dropped by large deciduous trees creates an ample amount of nutrients. A low input lawn requires 1 pound per 1000 square feet of nitrogen per year. A heavily wooded lot can produce 100 pounds of leaves per 1000 square feet providing enough nitrogen for the year.
Leaves in the lawn before shredding:
After Shredding:
If you do not have much lawn but have vegetable gardens, then you might want to save the leaves for the compost bin. Compost improves soil porosity by loosening heavy clay soils and retaining moisture in sandy soils. It also adds beneficial microbes that support root growth and break down the organic matter into soluble plant nutrients.
A balanced compost has an equal ratio of brown (dry) and green (wet) or carbonic and nitrogenous material. An over proportionate amount of either one will result in unhealthy microbial activity. Too much carbonic material will be too dry and take too long to break down. Too much nitrogenous material will become sludgy and anaerobic producing a bad smell. Leaves and wood are good examples of brown or carbon rich materials while grass clippings, herbaceous plants and food scraps are good sources of nitrogen rich materials.
There are many beneficial uses for your fallen leaves that can save you time and money in the landscape, not to mention the fossil fuel saved by eliminating the transportation of material. Even if you use machinery to process the leaves you will not use nearly as much fuel as transportation requires. Which method you choose to process your leaves or whether you simply decide to let them be is determined by the makeup of your property.

“Swales” and other rainwater-harvesting earthworks are an integral part of the sustainable landscape. Harvesting rainwater is by no means a new concept – humans have been capturing and storing rainwater for at least 6000 years, probably longer. From the cisterns of ancient Rome to today’s ubiquitous 55-gallon rain barrels, people have utilized the free and precious resource of rainwater for every water need from irrigation to bathing and drinking. Yet the use of tanks, cisterns and barrels can only be a small part of any sustainable water strategy.
This is because catchment itself is only part of the need. First, there is the simple matter of quantity – more water falls from the sky than we can possibly capture and use for our needs. For example, a 1-inch rainstorm falling on a 1000 square-foot roof generates more than 600 gallons of water – enough to fill a 55-gallon rain barrel almost 11 times. We could simply build a 600-gallon cistern to hold all of that water, but what if it rains 2 inches? Or 10 inches over a week-long storm? Where is that water going? And do we really need to hold on to 600 gallons? For what use? This also does not take into account the water that is falling on the rest of the yard.
Second, there is the issue of rainwater that flows over the landscape. Professionals and organizations are fond of referring to this issue as “stormwater management” – this water is a nuisance that must be diverted and shunted out to the nearest river as quickly as possible. We could not possibly disagree more with this stance. Stormwater flow is indeed a serious issue, as Colorado residents could tell you after the recent devastating floods in that state. However, a responsible stormwater management policy, combined with rainwater harvesting (viewing rainwater as a precious resource), would help to both collect and conserve water, as well as prevent flooding, erosion, and property damage.
Rainwater-harvesting earthworks are a key component of such a strategy. These earthworks include “swales,” terraces, rain gardens, and check dams. The term “swale” can be somewhat confusing – landscape and stormwater professionals use the term to denote a vegetated ditch that transports water. Permaculturists and rainwater harvesters use the word to describe a ditch dug on contour (running along an equal point of elevation crossways along a slope) with a berm placed on the downhill side of the ditch. When stormwater runs over the landscape, it is caught in these swales, and is allowed to slowly sink into the soil. Rainwater harvesting expert Brad Lancaster uses the term berm n’ basin to avoid confusion.
The catchphrase for both rainwater harvesting and stormwater management is “Slow, Spread, and Sink.” The idea is to slow the flow of water over the landscape, spread the water out evenly (instead of having it rush down one spot creating gullies), and sink it into the ground. Swales are an incredibly useful technique to accomplish this. The swale slows the flow of water by stopping it along a single point of elevation. It spreads the water, since it is a long ditch – much like a bathtub, even though water flows in from one point, the entire tub is filled with water. By stopping the water in one spot, it enables the water to sink into the ground.
Carving out swales for a recent project in Purcellville, VA
Permaculturists are often fond of saying that the cheapest place to store water is in the soil. Indeed, it costs much less to dig a swale than it does to purchase and install a large-capacity water tank – plus with just a tank, you still have to deal with the problem of water runoff from the tank’s overflow. In addition to capturing stormwater, swales serve many other important functions. By planting the swale berm with trees and shrubs (preferably fruiting plants, but hey, we’re biased), you can increase the amount of available water in the soil to your plants. This increased water supply boosts growth and fruit set. Ben Falk of Whole Systems Design has discovered, over 10+ years of experimenting on his farm in Vermont, that trees and shrubs planted on swales often exhibit twice as much growth as the same species planted nearby on flat ground. Over time, the increased amount of water infiltrated into the soil can also regenerate aquifers and revive springs downslope, creating even more of a water resource for people, plants, and wildlife.
Even the chickens love swales.
Of course, swales are only one tool in the rainwater harvesting kit, and may not be useful for all yards or properties. A detailed study of climate, soils, property size and other factors is the best way to determine which techniques are best for any particular situation. Usually a combination of various techniques, appropriately sited, are the best way to go. As seen in the pictures above, we recently installed a network of both diversion and infiltration swales as part of a permaculture landscape in Loudoun County. We’re excited to see how these earthworks solve drainage and erosion problems and provide free irrigation to the gardens. We’ll post more information over time as these systems develop and grow!

Fall, in general, is the best time of the year for planting. With temperatures slowly cooling down and an increase in precipitation, newly installed plants have a good opportunity to establish themselves. When it comes to the month of September specifically, this is a good time for planting cool weather annuals, whether they are petunias or pansies or vegetables like lettuces, arugula, spinach, beets and carrots. Perennials, trees and shrubs can be planted now but there is no hurry as they can be planted as late as December as long as the ground is not frozen. There is one family of plants that have a much smaller window of opportunity; their optimum period for establishment in the month of September. I am talking about our prized and sought after turf grasses. This is what we at Organic Edible Gardens are devoting our time to right now and I will explain a little about our process.
As the name suggests we practice organic gardening methods. In reference to lawns, this means no herbicides or synthetic fertilizers. How do you manage weeds without selective herbicides? You might ask. We burn them, or technically put we heat-sterilize them. With a specially made tool designed for organic agriculture, we pass an extremely hot flame over the weed, heating the water inside the leaves to a degree that destroys the cell walls killing the plant tissues. Now most weeds have rhizomatous roots which store energy in case their leaves die, so multiple applications are necessary to kill weeds permanently. Following a sufficient weed suppression schedule we add any necessary nutrients and adjust the pH of the soil as advised by a simple chemical soil analysis. An organically fertile soil requires organic matter; it is the food that the microbes eat in order to produce nutrients for the plants. Most lawn soils, especially chemically treated ones have low percentages of organic matter. In order to improve this, we apply a top-dressing of well matured compost. We follow this with an aeration to improve soil porosity, work the compost into the soil and to provide a good seed bed for the grass seed. Seed selection is important as certain varieties are best adapted to our climate. We also include certain non- grass seeds in our mixes that work well in turf systems whether by fixing nitrogen or filling in niches that other weeds would otherwise fill without altering the look of the turf. With a little help from Mother Nature in the form of rain, a short time later you can have a more drought tolerant, lush green lawn for your children to play in without the health risks of synthetic pesticides or contamination of the watershed.

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.
This was a really fun project – edible forest gardens, mandala gardens, meditation area, plants for the chickens, and TONS of beautiful, pollinator-attracting flowers everywhere. These were really fun clients to work with, very committed to regenerating the land, being good stewards, and growing their own healthy food in abundance. This will truly be a permaculture paradise!
