I'm in the north Okanagan, and apples, peaches, and plums all grow well in my neighborhood. I have one protected corner of my yard, shielded from the elements by wood fences, and I am dreaming of one day having a twenty foot tall flowering tree grown up out of that corner, to beautify the neighborhood. The past couple of years I have tried to grow Magnolia trees there, first a yellow butterfly imported as rootstock from PEI, and then a local hardy favorite from the local nursery. This town is full of beautiful flowering Magnolia trees, lining all of the city streets! But no luck in my corner. The first got to six or eight flowers and an equal number of leaves the first year, but the second year the leaves curled and it died. Next (more mature $100 tree) did ok the first year, and I tried preventative treatment with copper spray, but it didn't help. Leaves all fell off, and it's dead now too ( was hopeful this spring, but no luck). Should I excavate deeply and remove all soil before trying another tree? Can I ameliorate the soil somehow? Or do I just have bad luck or bad tree karma?? Every plant within three feet of this corner is THRIVING, including a very pesky invasive Chinese elm I have to cut back every year, huge lilac bushes, various other trees, grape vines... (Sigh) But so far no luck with Magnolia trees. And I am wondering if there is something else really showy that I can plant there. Ideally something that won't grow taller than twenty feet, since there is a 25kv transmission line right overhead... Any suggestions?
