My ‘Droughted’ Weedy Lawn: What do I do With it Now?

IMG_9160

This little stucco house, in the Woodstock neighborhood, is one of Julie’s favorites. It sits on a little rise clothed in an unbroken sea of Juniperus sabina Tamariscifolia (?) punctuated with several Italian Cypress. This landscape has been here for decades and appears to be completely weed free. It’s xeric with enough density to choke out weedy interlopers.  By not adding supplemental water many of our more common weeds are discouraged. Even if you wanted to apply a pre-emergent herbicide I don’t know if it could get to the soil. There is no way for anyone to enter this to remove volunteer Blackberries, Clematis, Canada Thistle or anything else for that matter. Junipers are strongly allelopathic containing chemicals in their shed foliage that build up in the organic layer on the soil surface discouraging successful weed germination.  Many other plants including our West coast Manzanita are allelopathic as well and can be used similarly.  Generally, allelopathic plants require several years to build up an effective layer of weed controlling old leaves to be effective, so our efforts will be necessary for some time.  At minimum don’t remove this layer of old and decaying leaves!  Junipers are also highly competitive in terms of their roots for water and nutrients.  Do I recommend this landscape…not necessarily, as it provides little ‘useful’ space offering little more than a very ‘defensible’ border, though it does have its attraction.   It provides shelter for some birds and critters, including rats, unfortunately, and fruit to those interested, while posing a minimal weed/seeding hazard to other landscapes.  It is a very simple landscape.

We can do much better than we have been doing with our landscapes…we have to!  It is incumbent upon each of us to grow our landscapes well, whatever they are, whatever they demand of us.  Our inability or unwillingness to do this is symptomatic of a society today that doesn’t  place priority and value on life, first!  (If you are reading this, you probably aren’t part of this ‘we’.)  The fact that we don’t have the time, resources or interest is indicative of how far out of balance our own lives are.  This isn’t a new phenomenon.  I don’t mean to shame or blame anyone here.  Modern societies have long been out of step.  We place a premium on our personal freedom, the idea that we have moved beyond nature, that technology will do for us whatever we need.  Nature will keep ‘chugging’ on without us so that we can devote ourselves to our more personal goals…and so ‘nature’ has been left largely on its own as if what we do will have no significant or damaging effects…but that isn’t really the way it is.  So, what do we do about that dead weedy lawn out front?

The Droughted Lawn

IMG_9080

A golf course is dependent upon a healthy, vital and uniform turf. It directly influences a courses playability. Even if you don’t play golf, courses evoke a calm with their pastoral, expansive lawns and views. This is a view down the 14th fairway at Eastmorland Golf Course. The perimeter rough areas receive no water and minimal maintenance. To the left is a swath of Blackberry. Other areas are over grown with weeds with fence lines draped with the invasive Clematis.

[A reader asked me to do an edited down version of this article to make it more accessible for those less interested, but in need of its message.  This is a stab at that.]

The suburban American lawn has been identified with the fall of nature by many.  Today, a good and green American, certainly us Portlanders are included in this, rejects the perfect monoculture of the lawn.  Nature:good; lawn:bad.  Our lawns demand water that could be better used growing food and assuring healthy fish populations, our lawnmowers spew air pollutants damaging to us all, our fertilizers leach away and move off site contaminating ground water and stream flow while our pesticides used on them, more directly attack nature all around us, all of this for no justifiable benefit, only fulfilling some narrowly defined human desire for an outdated aesthetic.  Detractors of the lawn argue against the waste of resources they require and they are difficult to justify if their purpose is restricted to providing a neat and ‘defensible’ perimeter for each house, the appetites of golfers and the youthful fantasies for power and dominance of sport, all increasing the consumption of land ‘stollen’ from nature to sate our hunger for it.  But this view of the lawn does it a disservice.

A Healthy Lawn, Drought Stressed Turf and a Meadow: Finding Our Way to a ‘Better’ Landscape

IMG_9080

A golf course is dependent upon a healthy, vital and uniform turf. It directly influences a course’s playability. Even if you don’t play golf, the landscape can evoke a calm with their pastoral, expansive lawns and views. This is a view down the 14th fairway at Eastmorland Golf Course. Imagine this drought stressed and brown overwhelmed with weeds…both the play and the ‘feeling’ the landscape evokes will be badly degraded.  The perimeter rough areas receive no water and minimal maintenance. To the left is a swath of Blackberry. Other areas are over grown with weeds with fence lines draped with the invasive Clematis.  Priorities are one-sided.

[The world is like a ball of string…pull on the loose end available to you, and you pull on the entire thing!]

Portlanders, Oregonians, often promote ourselves as being ‘green’ leaders.  Cleaning up the Willamette, the Bottle Bill, preserving our beaches as public property, state mandated land use planning, bicycling, recycling, mass transit…and it’s an apt description…to a point.  Combine this with our relatively low population, our huge, diverse and beautiful natural landscape, our progressive ‘weirdness’, and we are firmly on the national map, the envy of many places and a beguiling destination for those who find themselves looking for the laid back, ‘cool’ place, to be.  Our environmental righteousness is intoxicating and clouds our own vision of where we are and the work to be done.  A steady stream of new arrivals brings with them their own visions of Portland, based more on their own desires and marketing efforts than the on the ground reality, skewed by tinted glasses of Portlandia’s popularity, our own boosterism and the ‘boom’, probably transitory, commitment that big money has showered upon us.  Our little town is not what it once was, if it ever was.  But this is the nature of any place, it is many things, often contradictory, when looked at by its many very different inhabitants with their unique history’s and perspectives.

The Opposite of Freezing: Plants Have Upper Limits Too

It’s Sunday, July 30, and 87º outside, our forecasted high.  We’re at the front end of a forecast that is calling for two days over our record highest temperature ever recorded in Portland.  I’m looking at it now, Monday, the 31st calls for 92º, August 1 for 99º, 108º, a record, on the 2nd, 110º, another record, on the 3rd, before ‘cooling’ to 105º on the 4th and 95º the next day.  Our average high for this time of year is 82º.  The current record is 107º set on Aug. 8, ’81 and matched on Aug. 10, ’81.  That may not seem that high to people in the SW, but it is here and here is what matters.  Temperature is a local phenomenon.  It’s okay if we whine about it.  It’s hotter than we’re used to.  Hotter than what the local native flora and fauna are ‘used’ to.  For native species it’s not just about preferences, though we may use that word when we talk about their requirements and limits.   Continue reading

I hope that you will forgive me this departure into verse, prose, whatever this is…another thread in my life.  I don’t think it is too far amiss, because, after all, horticulture is the ‘art’ and science of growing plants.  Originally I began this as an idea for a children’s story, yes I did, the life of a particular Dandelion, but, probably due to my more recent reading on topics like photosynthesis, cellular metabolism and a biophysics response to the question of, ‘What is life?’…it has morphed…considerably.  When you read this, keep in mind that my intention was to write from the perspective of the Dandelion, a concept pretty incomprehensible to a modern American. 

The Taraxacum Cycle

Stories all begin with a single word, a seed, around which they grow, nurtured over time by the things we all share in common, family, history and experience.  They contain ‘truth’, but are not themselves true, because they must be told in such a way that they lure the reader in and are ‘believable’.  They are organic and grow within us and to the extent that they reflect our own ‘story’, that they meet our expectations, we stay with them and them with us, because there is no story if it is forgotten.  So, the author must manipulate what he knows, he must ‘lie’, to bring you in and keep you, weave truth and lie into a whole.  We take the stories you already know and introduce our own characters, set them in exotic though familiar settings, and, if a writer is good, introduce enough, but not too much, that is ‘new’, different from your cultural experience, your expectation, that you are affected by its unfolding, that you become a part of the story and look at your world in a different way, even if only a little bit.  The word here is Taraxacum.

Manzanita, Rock Roses and Friends: The Strength to Stand

Choosing the right plant is not an easy process.  We pick a design theme, make sure our plant choices are a good match for our site conditions, are compatible with their ‘bedmates’ and won’t become overly burdensome, in terms of the maintenance we are able and willing to perform.  There are a lot of variables here.  Our expectations of how a plant performs in the landscape, as individuals and as a composition, are important as we assess their performance over time and decide how we will respond to them.  Many of us are attempting to create gardens that require less of us in terms of maintenance, that fit the conditions on the ground with minimal intervention on our part.  We may chose to create a xeric garden to minimize or even eliminate supplemental irrigation.  If we do, the plant choices we make, their spacing, the size of plants we purchase, even the timing of the planting and the soil prep we do, are all important in our success or failure.  While we attempt to keep our specific site conditions and our goals in mind, we need to be prepared for the extremes of conditions, like weather, that can occur occasionally, even if only once every several years.   Continue reading

The Strength to Stand: Surviving the Load of Ice and Snow in Portland

img_7484

The morning after the big snow along the front of my house. To the left, splayed out and weighted down, is my Butia capitata. This one, from Argentina and not used to snow, had me worried, but it sprung back. The Oleander to the right, next to the sign, was bent down to the ground from its 8’+. Further back is one of my Chinese Windmill Palms, Trachycarpus fortuneii, bent under a snow load it is used to from high in the mountains of southern China.

Many of us who garden in the Pacific Northwest, and especially those of us in Portland this year, will be visiting our garden centers and favorite nurseries this spring and summer with a little more anxiety and need as we look for plants to replace those that have succumbed to this winter’s cold, ice and snow loads, all of which were more severe than what we have come to expect here.  But before we pull on our boots and don our rain gear to head off for shopping there are several questions that we need to consider before we make our purchases.  Not all of us draw up plant lists, but most of us at least carry in our heads a wish list of plants we have seen in other gardens, in magazine spreads and while on vacations, but if we want to avoid some major mistakes and move our gardens toward the kind of landscapes that we really want, we are going to have to put on our reality goggles and critically assess our choices…that is, if we want to avoid unnecessary losses in the future.
