I would like to ask if anyone has a Permaculture solution for a very windy roof garden.
I live on the Mediterranean Coast of Spain and there is plenty of sunlight for my roof container garden and there is usually adequate rainfall, but sometimes there are very strong winds and this has damaged a lot of my plants on the roof. I was thinking of putting some bamboo plants as a barrier but since they have deep roots , I am not sure if they can grow in containers. Any kind of panel could blow off the roof and be a potential danger to people in the street , so whatever I use as a wind breaker would have to be very secure and not able to fly away.
I welcome any suggestions.
