Another Great Blog!

I just have to write to let all of you know, in case you  don’t already, about MNN: the Mother Nature Network.  I personally just discovered the site today thanks to the writing of Chris Turner (@theturner on Twitter).  He provides a skillful skewering of a recent Globe and Mail article on the danger and horror of taking small children along for a bike ride.  Take note: this guy knows his shit!

Healthy Yards

In an online discussion held in a course at SAIT for the Environmental Technology program (ENVS470 – Advanced Environmental Considerations) someone asked if we’d all got our free rain barrels from the City of Calgary yet.  “The City does not give rain barrels away,” I retorted.  “They cost up to $80 outside the sale in May.”  Turns out I was wrong about that.  “You have to sign up for the Healthy Yards program,” I was told.  So I looked in to it, and signed up right away.

I expected to have to wait until 2012 to get my equipment, as the student said she had signed up too late last year to get hers, so she gets it this year.  Imagine my surprise, then, when I got an email informing me that I’d been accepted to the program for this year and would get my equipment soon.  This all happened in mid-May.  I now have got my rain barrel and composter, and am eager to get everything going.

Now some background.  The City of Calgary Healthy Yards program is a two-year commitment on the part of the participant, with some very simple requirements that are very easy to comply with.  While it is free to participate, there is a limit of 200 participants per year – hence the waiting list described above.  As mentioned, participants receive a complementary rain barrel and composter, as well as a DVD with videos demonstrating and explaining how to use this equipment and

  • how to use a mulching mower,
  • how to select and plant water-wise alternatives for Calgary’s unique climate, and
  • responsible pest management.

The basic requirements of the program are (if I’ve missed something, please let me know!)

  • use the provided equipment,
  • practice grass-cycling,
  • use a push-mower, or at most a 4-stroke gas mower,
  • limit or eliminate pesticide and artificial fertilizer use.

These are all pretty simple.  The Healthy Yards Orientation will provide you with more information about how to compost, how to use your rain barrel, how to grass-cycle, and much more.

One part of growing a healthy garden is to have the right soil.  Soil is described, at least in part, by its texture, and one of the easiest ways to determine this is to use the jar test.  Soil textures are often described by terms such as “clay,” “clay loam,” “sandy clay loam,” and so on.  The Healthy Yards program encourages participants to determine their own soil texture using the jar test.  It is not difficult – in fact, it is probably the easiest (and cheapest) way to do it.  Native soils in Calgary are generally clayey and require amendments such as peat, compost, vermiculite, et cetera, to become more workable.  Unfortunately, the process of developing a good, healthy, organic soil base can take several years of careful attention.

The funny thing is that I learned all about the jar test, as well as a couple other soil classification methods such as sieve analysis, in the laboratory component of my course in Sampling and Analysis at SAIT.  The basic idea with the jar test (Procedure: Jar test for determining soil type) is to collect a representative soil sample from your garden, place it in a jar (such as a mayonnaise jar), fill to about 3/4 with water, add some borax or non-foaming dishwasher detergent, seal the jar, shake vigorously for about 10-15 minutes, and then let the jar sit for 2-4 days.  The different components of the soil will separate at different rates based on particle diameter and density (Stokes’ law), so that coarser materials will settle first and clayey particles will settle on the surface.  By measuring the thickness of each layer (differentiate them by colour) and comparing it with the thickness of the entire soil column you can determine the percentage composition of sand, silt, and clay.  Then refer to the soil texture triangle to classify it.  (Apparently the Canadian system uses only clay and sand proportions to classify.  The link provided goes to the more familiar US version.)

Anyway, the point is that the Healthy Yards program is cool, easy, and inexpensive.  There is no reason you shouldn’t get going with it yourself!

A Sea of Yellow?

Common Dandelion

The common dandelion.

Last August (2010) I wrote about the removal of the common dandelion (Taraxacum officinale) from the Alberta Weed Control Act as a noxious weed.  Well, it appears this is still quite a contentious issue (indeed, I doubt that it ever will cease to be), generating a lot of commentary across the board.  To call it a debate may be misguided – it appears to me as more of a fight as people become more and more impassioned.  Former Calgary City Councillor Ric McIver appeared on CBC Radio’s The Current this morning in an attempt to argue, apparently, for the use of toxic and harmful pesticides to control dandelion populations.  Have a listen to the piece and see what you think.  It is not only Ric McIver appearing, but also Simon Wilkins, coordinator of integrated pest management for the City of Calgary.  In my (humble) opinion, Mr Wilkins provides the more sensible, logical, and rational argument.

Just to be clear, the removal of dandelions from the Alberta Weed Control Act does not mean that municipalities cannot elevate the plant to “noxious” status themselves (via bylaws) and thereby control them.  While this is not likely to happen, all it really means is that the City cannot issue citations for dandelion “infestations” unless they reach 15 cm in height or greater.  Further, in my previous article I mentioned that the City of Calgary failed to pass a (cosmetic) pesticide ban in December 2009.  This means that there is also nothing keeping residents from spraying poison all over their lawns in an effort to control a simple, harmless little plant.  (Note that this poison may be transferred to pets and children when they play in the grass.  In the case of dogs and cats, particularly, which often practice self-grooming, this can have decidedly unpleasant consequences.)

Non-Chemical ControlPesticide-Free Zone

It should be noted that there are a variety of dandelion control methods that do not involve the spraying of poison.

Of course, there is always the basic method of pulling them up as they appear.  This can be good exercise, but is tiring, time-consuming, and often frustrating.  A better and more effective way is to keep a healthy lawn.  This can be done, at least in part, by following these suggestions from the City of Calgary’s Healthy Yards Lawn Care Guide:

  • mow your lawn to 7.6 cm (three inches) in length
    • keep mower blades sharp to produce clean cuts and promote better grass health
    • the three-inch length provides shade to roots, protecting them from heat and helping to prevent weed seeds from germinating
    • too-short grass is susceptible to weed and pest problems, takes longer to recover from drought periods, has shallower root systems, and does not hold moisture as well (thereby costing more time and money)
  • limiting water to one inch per week (get a rain gauge or use an inverted frisbee as a guide)
    • keep track of rain received over the week
    • avoid watering in the evening
    • avoid fixed watering schedules to help keep grass hardier in times of drought
    • manual watering with a hand-held hose and shut-off nozzle is the most water-efficient method
    • avoid misting sprinklers or those that spray high into the air, such as the oscillating variety
  • aerating your lawn
    • improves rooting
    • increases migration of water, nutrients, and oxygen through soil
    • encourages activity of micro-organisms in soil
    • aerate in at least two different directions to ensure good coverage
    • leave soil plugs or cores on the lawn to be re-integrated
  • dethatch and power-rake your lawn
    • removing thatch allows air, water, and nutrients to migrate into the soil easier
    • if you are not experienced in power dethatching, hire a professional
    • give some extra water in the days after dethatching
  • topdressing
    • a great way to level the lawn, or build it up to the desired level
    • fills holes or low spots
    • encourages growth and may add nutrients (depending on type of topdressing used)
    • allow grass to grow through by not watering for a couple days after topdressing
    • don’t topdress if rain is in the forecast, as it makes a big mess and does not rub in well

There are a variety of other methods that can be found by simply using Google.  Weeds thrive by out-competing the non-native grasses we have been brainwashed into using.  Keeping a healthy, luscious lawn can help to turn the tides in the other direction.

Happy gardening!

Rising Gas Prices Anger Consumers

Living in the heart of oil country, people are often baffled when prices go up at the gas pumps, and I count myself in that demographic.  However, with all the complaining people do, they seem to believe it is up to Big Oil to fix the “problem” (after all, they’re just after more money right, so why not gouge the consumer?) rather than taking personal action.  No, I’m not talking about protesting, fire-bombing X Co’s corporate headquarters, or some (other) form of domestic terrorism.  Rather I am talking about behaviour modification.  I know this is a difficult concept, so I will repeat it: behaviour modification.

WTF!?

I know, I know.  Behaviour modification can be difficult (though it doesn’t need to be), and besides, that “other guy” is a lot worse – why should you change when he won’t?  Well first off, your pocket-book will thank you.  The steam/smoke emitted from your debit/credit card could be greatly reduced.  Of course, this all depends on what you drive (assuming you drive at all), how often, and how far on average.  If you don’t drive at all then you’re already laughing (please drop me a note and let me know some limited details about yourself, why and how long you have been car-less, and how you’re getting by).  If you do currently drive, you should know that there are options.  I will discuss some of them below.

Drive Less

This is perhaps the most obvious option to many people.  Not everyone is able to do this, such as those who drive for a living (taxi drivers, couriers, law enforcement, etc), but if you can it is an easy way to start cutting your ties with the corner gas station.

Now, I can already hear some of you complaining “If I can’t drive, I’ll just be stuck at home all the time.”  I call bullshit on that, one of the laziest excuses out there.  There are a variety of options available, not least of which the appendages attached to your hips (unless you don’t have legs, in which case you probably have a wheel chair and use your arms or some other method to get around).  Benefits of walking include general fitness, socializing with neighbours, reducing local crime rates, and much more.

Of course, it may not be feasible to walk to work, in which case there are other options.

Public Transit

Seen by some as a blessing and by others as a curse, public transit (PT) is certainly a viable option.  Some cite germs or “wierdos” as reasons not to use PT, and others may cite cost.  However, those citing cost as a factor usually do not drive or have never driven.  Fact is, using PT can save you a significant amount over buying fuel for your car/truck.  It is also possible to meet some… interesting… people (both good and bad, I admit).  Finally, you may get some extra reading, work, surfing, or whatever in while riding the train or bus.  Or… you can try to get some sleep.  Just don’t sleep past your stop (I’ve done that before and it was horrible).

Cycling

This is another option that can promote personal health and fitness.  Cycling is very easy, a lot of fun, and generally an excellent mode of transport.  Granted the initial investment in equipment can be expensive, but compared to driving, it pays itself off in spades in a relatively short time.

Indeed, because of accessibility and speed, cycling is one of the best and most effective ways to explore an area.  While many pathways in Calgary don’t really go anywhere (that is, there are no specified destinations), they do often pass through beautiful areas.  Riding to work is an effective way to stay fit – some even continue through the winter months!  If you’re not comfortable riding in winter conditions, I would advise riding in spring/summer and using PT through the winter.

Relocate

For some people, it may be feasible to move to a location closer to where you work.  If this is the case, you should be able to easily walk or cycle to work.  If you’re careful about your new location you should even be able to walk/ride to the local grocer!  What a great way to save money, get exercise, perhaps even have a bit of quality family time.

Be Creative & Innovative

As mentioned above, there are numerous ways to reduce your reliance on your car/truck.  While moving is rarely a fun or even enjoyable experience, relocation can have some wonderful outcomes.  Moving in to a transit-oriented development (TOD) can have the benefit of living near the workplace, the grocer, and many other services.  The same can be said of many other walkable communities such as Calgary’s Kensington or Inglewood.

Yet another option is car sharing.  More and more communities have car sharing programs available for residents.  With car sharing programs you are still paying for fuel, but only what you put into the vehicle.  And you only use the vehicle when you really need it.

Downsize

Now, of course, there will always be people who are unwilling or unable to get rid of their vehicle(s).  One way to get around this, then, is to downsize.  Just buy a smaller, more fuel-efficient vehicle.  If combined with the application of one or more methods discussed above, this can have a significant impact on your personal chequebook and lifestyle.  In reality, it is only such behaviour changes that reduce fuel consumption, which in turn can help lower prices at the pumps.

In a way, this operates as a carbon tax of sorts, encouraging people to buy smaller cars requiring less fuel.  But if you really hate the idea of a carbon tax, it’s probably best not to think in those terms.

All About Seeds

On Friday February 25, 2011 I attended a very enlightening presentation called “All About Seeds”, presented by the  Calgary Horticultural Society and the Unitarian Church of Calgary’s Green Sanctuary.  It was a very interesting evening with three lovely ladies speaking about different aspects of gardening directly from seed: indoor seed starting, seed harvesting, and winter sowing.  Each is summarized below in sections below the fold.

Gardening Season Approaches

I am excited.  Classes are nearly finished, and gardening season is fast approaching.  The only thing that would make it better would be having a job lined up for when I graduate.

Anyway, there are some events coming up for those into gardening, both of which I will  be writing about here as they happen.

  • All About Seeds
    Friday February 25, 2011
    19:00 @ the Unitarian Church of Calgary
  • Seedy Saturday
    Saturday March 19, 2011
    10:00-15:00 @ Hillhurst-Sunnyside Community Centre
  • Garden Show
    Saturday April 9, 2011 – Sunday April 10, 2011
    Spruce Meadows

So why am I excited about gardening season?  Well, for one thing, gardening is fun and interesting.  But I am also very excited  because, for the first time ever, I am planning  to try growing some grain crops.  Between the All About Seeds evening and Seedy Saturday, as well as the resources available on the intertubes, I feel confident that I will be able to learn enough of the basics to be able to grow and collect enough grain to plant next year, and hopefully also make a small amount of flour.  I’m planning at the very least to plant some wheat, but would also like to plant some quinoa and perhaps barley.  Couple all that with growing smaller items such as carrots, garlic, onions, and asparagus, as well as starting a rain barrel and continuing with worm composting, and it should be a fun and exciting season!  I do plan keep you all posted on here as things progress and as I learn more, so stay tuned.
