I am looking for a global garden supplies company which can supply large adjustable surround supports (tripod or quad pod) for plant containers sites on hard surfaces such as patios, gravel and or earth beds. For example where a container with a growing plant has become top heavy and the container cannot support itself on windy days without a footed frame. The plants are typically greater than 1.5m tall and the containers are greater than 0.5m diameter at widest. I am using bamboo canes in the earth beds for now however I am looking for something elegant for the patio. The only other solution is to repot the plants in larger containers with added weights in the base. However I would prefer to work with containers I have. Thanks in advance for any recommendations.
