Toyon in the Pac NW?
I was wondering if anybody in Western OR or WA has had success with toyon (Heteromeles arbutifolia). I tried one in a partial sun area on well-draining clay back in mid-September, and it had leaf spot issues within a couple of weeks. (Outside of an initial deep watering upon planting, it didn't get any water before the leaf issues appeared.) The previous owner of our house amended this soil with perlite and probably some organic material (possibly as recent as two years before I planted here), so it's conceivable that some of this stuff was still present in the soil at the time.
I've read one success story up near Portland when a toyon was planted under the canopy of a mature conifer (that presumably sheltered it from a lot of winter moisture). But nothing outside of that. Most of the regional nurseries that supply plants for xeriscaping don't sell toyon, so I'm wondering if it's just not a very doable shrub for this region.
