I would like to put an acer palmatum in a spot about two metres from the corner of the house and a similar distance from where the perimeter drain is buried on the way to the storm drain. There is a slope in the lawn which would put the tree about 1.5 to 2 metres above the depth of the pipe. The tree is about 2 metres tall now. Does anyone know if the roots will make it to the drain pipe as the tree matures? I would like to plant something tall-ish in that spot - good feng shui and all - and the maple seems to be the right scale.
