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? Continue reading →
