BioHeat's time has come

It's going to be an exciting year for the Joe family. We've decided to make the switch this year to B20 BioFuel (80% petroleum, 20% vegetables) for the 2006-07 heating season. As my partner and I have grown more committed to our efforts to minimize our impact on the planet, we have decided that money can no longer be a barrier to following our values in this area. Hence, in February we bought a Honda Civic hybrid that gets nearly 50 miles to the gallon and has very low emissions. We continue to purchase as much locally-grown and/or organic food as we can find. We have reduced our use of plastics. And now we are going the BioFuel route. And the best news about BioHeat is that the prices are now competitive with petroleum.

We received notice, through the Maine BioDiesel newsletter, that local supplier Independence Fuel in the neighboring town of Durham, is among several BioDiesel companies in the state now offering fixed-price plans for BioDiesel. This is a huge step in bringing Bio Fuel to the mainstream. The product is cleaner, safer and more environmentally friendly than pure petroleum, and 20% of the product is produced in this country! In prior years pricing wasn't competitive, and the companies couldn't offer the security of the fixed price contracts that are so important with the constant rise in oil prices. This year is different, however. The contracts are available, and the pricing actually beats that offered by my former supplier. I was willing to pay more for all of the benefits that BioFuel provides, so I'm certainly willing to pay less. In fact, I signed up for a budget (10 payment) plan that is 10 cents cheaper than the price-cap pre-buy price of my incumbent supplier! I save money and I don't have to write a check for $1,500 this summer? Where do I sign?

According to Independence Fuel's web site, they still have fixed-price plans available. Click here to find other BioFuel dealers in the state. If you don't live in Maine (and why don't you?), check the map to find a supplier near you.

Freedom Lawn (or, How Hannah Holmes Changed my Life)

I have what most American suburbanites would describe as “a crappy lawn.” The US ideal, as promoted by the people at Scotts, Chemlawn, and even the environmentally friendly Nature’s Lawn, is a lush sea of green grass. Neither flower or non-conforming foliage must tarnish the landscape.

My lawn, on the other hand, is comprised of clover, dandelions, paintbrushes, buttercups, strawberry vines, baby ferns, some purple flowers that I kind of like (and some white ones, too), a bunch of things that I should know the names to by now, and at least three varieties of grass, including the crab variety. It’s a mess.

Is this any way to run a lawn?

I even went so far as to contract an assessment (“high weed content”) and quote from Nature’s Lawn a couple of years ago. Despite their promises to not use chemicals and pesticides, I decided that I had better things to spend a few hundred dollars per year on. At least my lawn is already green. Besides, I don’t live in a subdivision, I live on a country road where you can’t see anybody else’s lawn while standing on mine. I figured I could wait before trying to strengthen the grass (and choke out the weeds) on my own.

Then I met Hannah Holmes, who talked me out of even that.

That’s not entirely true. I didn’t actually meet Ms. Holmes, though I live only about 20 miles away from her South Portland home. I did, however, receive a copy of her 2005 book Suburban Safari, in which she spends a year documenting the actions of the flora and fauna in her own back yard. And right there on page 103 Holmes introduced me to the concept of the Freedom Lawn:

The freedom applies both to the plants and the people, the latter of whom
needn’t water, fertilize, pesticize, or other otherwise interfere. Nurseries now
sell Freedom Lawn seed mixes, for lawn owners who life in parts of the world
that have been shortchanged in weeds. But even before I came across the official
term, I thought of my yard as a Darwin Lawn. Whatever could survive the mower
and the drought was welcome to stay.

That’s what I have! A Freedom Lawn. And it’s a good thing, too. Holmes later writes about the problems with having a lawn that is comprised of one species of grass:

Monocultures are sickly, that’s a scientific fact. While it’s true that some
plants fight each other, it’s also true that a high diversity of plants protects
everybody. Together, the plants pool their talents. Each plant probably repels a
few harmful insects. Each probably attracts a beneficial insect or two. The
wastes of one species feed the roots of the next. The bold produce shade for the
shy. They also dilute themselves, making it tougher for diseases to roll from
clover to clover, or ryegrass to ryegrass. This has been proven in experiments:
A plot of grassland hosting many species produces a lot more total greenery than
a plot with fewer species. Even the most carefully tended plot of a single
species can’t compete.

Rather than spend a lot of time an money and resources forcing your lawn to be something that it doesn’t want to be, and isn’t all that desirable (from an ecological standpoint), Holmes and the Freedom Lawn community suggest just letting the thing run free. And indeed, since I stopped applying water and fertilizer a few years ago, my lawn has become more lush and green and (dare I say) healthier than ever before.

Looks OK when you mow it!

Suburban Safari is full of such practical advice. While promoted as a chronicle of the activity in Holmes’ back yard over the course of a year, it is much more than that. Holmes takes on such important topics as global warming, disease, invasive plants and animals, and, importantly, water diversion. The last topic isn’t one that we hear about much in New England, which receives ample precipitation most years, but it is an issue in the desert southwest where rivers and groundwater are depleted to feed agriculture, humans and, increasingly as the population grows, human lawns. It takes a lot of water to grow grass. Growing grass where there isn’t a lot of rainfall requires one to divert water from other, more practical uses. The problem is exacerbated by the fact that human population centers require a lot of pavement, which doesn’t absorb rainfall but instead sends it down into the sewers. Less absorbed rainfall means more water needs to be diverted. It’s a downward spiral.
The book does live up to it’s original billing as well, and it’s an interesting story. Like any good story, there is romance, violence, and the struggle to survive. It’s man vs. nature as well as nature vs. nature. We follow crows, chipmunks, squirrels, ants, slugs and spiders. We also follow oak trees, apple trees, pear trees and grape vines. We see how plants, animals and humans fight amongst themselves for space. Most enlightening was Holmes’ description of the defense mechanisms employed by the trees. We all know that plants are living things, but Holmes portrays them as, if not thinking beings, species that are able to adapt to threats and changing conditions, and even react with unseen, unknown defense mechanisms. It’s a fascinating read.

There is much to be learned from Suburban Safari. Some of it is in the “cool to learn something new” department, like the aforementioned discussion of the trees. But much of it is practical advice for what we as humans can do to preserve the natural world around us. It is an eye-opening look at how our attitudes toward rain water, energy usage, chemicals and invasive species affect our communities and our lives. Highly recommended.
