Strawflowers for the Win

When I was still in horticulture school and we finished our spring plant sale, many flats of strawflowers (Xerochrysum bracteatum) were sadly left over. It's not surprising -- they weren't blooming yet, so unsuspecting customers usually passed up the four-packs of lance-shaped leaves for the early-blooming annuals that provided instant gratification. I admit I had never given them much thought until I brought some of that neglected merchandise home, potted them up, and watched them blossom. In the years since, strawflowers have become one of my favorite annuals, and I always make sure to plant a bunch in the garden each spring.

What's so great about them? They come in a variety of bright warm colors (and yes, so do lots of other flowers). But these annuals are robust and long-lasting. Its bracts are papery and petal-like, and they hold up throughout the season. The same flower will respond to the weather, closing during cool, damp night and opening again in the warm sunlight. The color persists for a long time as well.

It's December and I'm impressed with how much these flowers are holding on. The same plants are still forming new buds, and the spent flowers have reseeded all over the garden. I've practically got a ground cover of strawflower leaves in one of my beds, which is a good thing to keep in mind for future seed collecting. I also haven't noticed any major pest or disease problems with them, and so far the deer and rabbits haven't been interested.

Besides all that, they're wonderful in bouquets, and also as dried flowers. My wife and I grew and harvested strawflowers to throw at our wedding. Just an all-around great plant.

Most of those "weeds" that you see are self-sowing strawflowers. If only there was enough time in the fall to see them flower!
This is what they look like in December. They obviously aren't opening much now that it's cold, rainy, and darker, but these plants continue to hang on.
Still forming new buds!

Why I Criticize Lawns


If you've known me for any amount of time, and the subject of landscaping and lawn care has come up, you've probably heard me rail against lawns. I'd like to take a moment here to elaborate on my reasons why.

A big part of it has to do with sustainability, especially when it comes to maintaining a lawn up to the weed-free, short-length, green-all-year-round standards that most Americans have been conditioned to strive for. It requires constant mowing (and the energy consumption -- usually gas -- that goes along with it), fertilizing, weed removal (which often means regular application of herbicides and pesticides), and of course watering to get that lawn as close to golf-course perfect as you can. As time goes on, water scarcity is going to become an even bigger issue than it already is, and as the climate changes, we'll all need to question our priorities when using these finite resources.

Another reason is that I'm tired of this monotonous, wasteful work -- physically as well as psychologically. In the beginning of my horticulture career, I worked for a landscape maintenance company to gain experience in the field, and the majority of the job became a tiresome repetition of mow, edge, blow, and then drive to the next account as quickly as possible. Lifting and operating heavy machines, consuming gallons of gas between the equipment and the commutes, creating all that noise, obsessively trying to blow every speck of debris off the hardscapes.... I hated it. Lawn care was never work that I felt proud of. I felt the wastefulness of the whole labor-intensive routine that we repeated from week to week, and it all seemed so pointless. Now that I'm a homeowner, I have no desire to continue that drudgery on my own property.

Personally, I feel that there are better uses for the space. I want to grow food and raise chickens, along with some ornamental garden beds that have well-placed, drought-tolerant plants that serve other ecological functions, such as encouraging pollinators. As much as possible, I want to employ permaculture principles to my landscape choices to maximize the benefits of the land while also working in harmony with nature as much as possible.

Those are all good reasons. However, it was discovering the history of the lawn that really made a difference for me. One of the recommended texts during my environmental horticulture class was a book called American Green: The Obsessive Quest for the Perfect Lawn by Ted Steinberg. I know, I know, a whole book about lawns? How nerdy and boring could that be, right? But it's actually really informative and engaging. Why do people spend so much time, energy, and money on their lawns? I found it both fascinating and infuriating to understand where our turfgrass standards come from. Steinberg's book delves into the history of suburbia and reveals the manipulative marketing that transformed our ideas of what a "normal" yard is supposed to look like. It's another ugly story about the dark side of capitalism, with large doses of status anxiety, conformity, conspicuous consumption, and outright racism.

The growing obsession with the lawn went hand in hand with the rise of the suburban American Dream, which took off during the mass-produced housing developments of Abraham Levitt and his sons. The Levitts carefully manufactured their communities, constructing houses in an assembly line fashion to optimize production and lower costs. The design of these homes, yards, and community layouts was all tightly controlled in a picture-perfect little utopia, complete with strict rules about the appearance of these homogeneous properties. These towns, with their uniformly constructed houses and manicured lawns, seemed to be the epitome of postwar success in America... but they were also steeped in the prejudice that has been such a large part of American history. The Levitts were known racists, only selling homes to "members of the Caucasian race" and actively promoting segregation. They weren't subtle about their prejudice.

Bringing up the Levitts might seem like a detour, but those manufactured neighborhoods from the 1940s and onward have undeniably become the stock image of what the ideal American property is supposed to look like. It's a powerful symbol... and it comes with a lot of baggage. The immaculate lawn is a part of it. Especially when you understand how businesses like Scotts Company were promoting ever more obsessive trends in lawn care in order to sell their products and services. The marketing propaganda was so pervasive and influential that it set the standard for our societal norms. In most homeowners' minds, a manicured lawn is such an obvious default setting for their yard that they don't even question why they think that way.

Like I said, it's an interesting history, in that annoyed-our-society-has-been-duped sort of way. Ted Steinberg's book says everything about the subject that I want to express, and his writing is more entertaining than mine. I highly recommend checking it out. If you'd prefer something shorter, Freakonomics Radio made a podcast called "How Stupid Is Our Obsession With Lawns?" which includes an interview with Steinberg.

I'll wrap this up with some words from Michael Pollan, who has a beautifully written article -- Why Mow? The Case Against Lawns -- that blends rationality with poetry. He describes his changing relationship with the lawn, and like so much of his writing, the story really hits home:
The more serious about gardening I became, the more dubious lawns seemed. The problem for me was not, as it was for my father, the relation to my neighbors that a lawn implied; it was the lawn's relationship to nature. For however democratic a lawn may be with respect to one's neighbors, with respect to nature it is authoritarian. Under the mower's brutal indiscriminate rotor, the landscape is subdued, homogenized, dominated utterly. I became convinced that lawn care had about as much to do with gardening as floor waxing, or road paving. Gardening was a subtle process of give and take with the landscape, a search for some middle ground between culture and nature. A lawn was nature under culture's boot.
Mowing the lawn, I felt like I was battling the earth rather than working it; each week it sent forth a green army and each week I beat it back with my infernal machine. Unlike every other plant in my garden, the grasses were anonymous, massified, deprived of any change or development whatsoever, not to mention any semblance of self-determination. I ruled a totalitarian landscape.
Hot monotonous hours behind the mower gave rise to existential speculations. I spent part of one afternoon trying to decide who, in the absurdist drama of lawn mowing, was Sisyphus. Me? A case could certainly be made. Or was it the grass, pushing up through the soil every week, one layer of cells at a time, only to be cut down and then, perversely, encouraged (with fertilizer, lime, etc.) to start the whole doomed process over again? Another day it occurred to me that time as we know it doesn’t exist in the lawn, since grass never dies or is allowed to flower and set seed. Lawns are nature purged of sex and death. No wonder Americans like them so much. 
And just where was my lawn, anyway? The answer’s not as obvious as it seems. Gardening, I had come to appreciate, is a painstaking exploration of place; everything that happens in my garden -- the thriving and dying of particular plants, the maraudings of various insects and other pests -- teaches me to know this patch of land intimately, its geology and microclimate, the particular ecology of its local weeds and animals and insects. My garden prospers to the extent I grasp these particularities and adapt to them.  
Lawns work on the opposite principle. They depend for their success on the overcoming of local conditions. Like Jefferson superimposing one great grid over the infinitely various topography of the Northwest Territory, we superimpose our lawns on the land. And since the geography and climate of much of this country is poorly suited to turfgrasses (none of which are native), this can’t be accomplished without the tools of 20th-century industrial civilization -- its chemical fertilizers, pesticides, herbicides, and machinery. For we won’t settle for the lawn that will grow here; we want the one that grows there, that dense springy supergreen and weed-free carpet, that Platonic ideal of a lawn we glimpse in the ChemLawn commercials, the magazine spreads, the kitschy sitcom yards, the sublime links and pristine diamonds. Our lawns exist less here than there; they drink from the national stream of images, lift our gaze from the real places we live and fix it on unreal places elsewhere. Lawns are a form of television.

Oh, How I Miss Homegrown Tomatoes

I haven't had much time for food gardening while I build and get settled into the new house and community. Tomatoes, more than any other fruit or vegetable, make me miss it the most. It's hard to deny the incredible difference in taste between store-bought and homegrown tomatoes. This PBS segment with renowned seed saver and farmer John Coykendall explains why.

When is the best time to water my plants?

While it's always good to plan wisely about watering your lawn and garden, I find it particularly important in times of drought, when our plants rely on us for hydration.

The best time to water -- be it hand-watering or using an irrigation system -- is in the early morning, before the temperature gets warm. During this time, the air is still cool, and therefore you won't lose a lot of water to evaporation. More water is penetrating the soil and not being wasted, which is especially important if you're using a sprinkler system that sends water droplets through the air before hitting the soil where the moisture is actually needed. This also gives plants the water they need throughout the day, and won't have to spend the first part of it dry and wilting. As the temperature gets hotter, the water is already available and the plants are better able to combat the heat. If any water got on the leaves, it has the whole day to dry out before the air gets cool again at night.

If you have an irrigation system with a timer, watering at the correct time of day is a no-brainer. Set it for the early morning, and you're good to go. (Though you should still look below for some other water-savings tips.)

However, without automatic irrigation, it's not always possible to water at the preferred time. What are some second-best solutions?

Particularly if we're in a drought situation, the honest answer is that watering any time is better than skipping watering altogether because it isn't the best time of day (but I'd make a case against the lawn -- see below). If late afternoon or early evening is the only time available, then it's better than nothing when your plants are thirsty. However, there are a few things to keep in mind:
Please, stop watering the air!

  • Sprinklers: Water the soil, not the air! This rule applies no matter what time of day you water, but it's especially important when it's hot out. The roots are the part of the plant that needs water, so your goal should always be to get the most water into the soil. Realize that when you use a sprinkler system during the hot afternoon sun, a significant percentage of that water simply evaporates, and another portion of it just wets the leaves and doesn't get to the roots. This will vary depending on the type of sprinkler head. Some release a fine mist, which means a higher evaporation rate. Others are a little more water efficient, spraying larger droplets to reduce evaporation. Nonetheless, it's still unwise to use sprinklers at the hottest time of day, as there will always be some amount of evaporation happening. 
  • Hand watering: Again, water close to the soil. The same idea goes for using the hose or watering can. Keep the water as close to the soil as possible. Many hose nozzles have different settings, from powerful jet to fine mist. If it's hot and you're spraying a wide area, just remember that any water droplets traveling through the air will partly be lost to evaporation. It takes a little more effort to move the hose closer to the plant roots, but less water will be wasted.
  • Keep the leaves dry. If watering later in the day, avoid getting the leaves wet, as there won't be enough heat left for this water to evaporate. Cool, moist leaves will encourage fungal problems, such as powdery mildew.
  • Let the lawn go brown. I know this can be difficult for many people who have a hard time accepting a less-than-perfect lawn. But the truth is, keeping the lawn green during drought months requires a lot of water, and it's worth it to evaluate how necessary this is, and lower your tolerance. The grass will go dormant, but it's not going to die. If your area has a particularly long stretch without rainfall, you can give it some water to keep it alive, but don't overdo it. Every year water is becoming a scarcer resource (just look at what's already happened in California and in other parts of the world), and it's time to reconsider the importance of a perfect green during the summer months.
  • Avoid installing new plants during the summer. New plantings require a lot of TLC. Regular watering is necessary during the first couple of years to get your plants (even the "drought-tolerant" ones) established, and this is even more challenging during long, hot, dry days. In the spring and fall, when rain is abundant, it will be much easier to get these plants going without stressing them out during the hottest months.
  • Mulch. In your garden beds, use a top layer of mulch to retain moisture.
  • Check for leaks. Evaluate your plumbing, hoses, and irrigation equipment for leaks, and make repairs as soon as possible.

No one wants to waste water. It's an urgent environmental issue, but also a personal one. Whether you buy your water from the city or have your own well, you don't want to waste your money or finite water supply on inefficient irrigation.
