If I plant a shrub which gets to 6ft high with a natural 6ft spread, how
close can I plant it to a fence without it becoming lopsided to such a
degree that the plant will suffer? For example, if I plant it 1ft from a
fence, will I have problems later when it has 1ft of growth on the fence
side but 3ft of growth on the garden side? I'm thinking of it leaning and
falling over under the weight of the extra growth especially in parts of the
garden where it's prone to waterlogging.
