I bought a Magnolia grandiflora in a 100 Litre container. It needs to sit tightly next to a fence, with intent to block a neighbouring property. Now, here is the problem... The tree is 2m tall, but blocking the neighbour requires closer to 3m.
This is a slow growing tree, and I want my privacy sooner rather than later.
What problem would I have if I plant the tree just a tad high -- i.e. I put it into a hole in the ground, which is, say, only 1.5m deep? Does anything change if I put a 0.5m frame around it (it's next to a deck, so I don't want lots of additional dirt in the area).
------ Additional info ------
The Magnolia is a 'Kay Paris'. To add complication, I have clay soil, which I believe isn't ideal for this tree (happy to be corrected). I still want it very close to the fence, a bit less than a foot. I am happy to water it regularly, and I suspect it may even work despite a 'rain shadow', as clay tends to hold moisture. But at such short distance from fence, the rear branches will be squashed a bit tightly, at least for a year until I cut them. So... will this work?
