I live in a condo that had all the limited common gardens removed from in front of a concrete retaining wall that directly affects what I look at. We have to use plants in pots, but am wondering if I can set a few pots along the wall with vines in that would cover the grey concrete and quickly provide some greenery again. The wall is about 76 feet long and from 7 feet to 9 1/2 feet tall. My neighbour and I have had our garden suites turned into concrete cell blocks and are desperate for some creative and not too costly solutions. Strata is very reluctant to replace the limited common gardens (that's another issue!) Can anyone provide some ideas or assistance? Thank you.
