I recently bought a Consolea Rubescens cactus on ebay and sadly on arrival, discovered that it has many brown patches and areas of scarring/damaged skin (which weren't visible on the ebay photos!)
Is this something caused by pests or mites that I can treat? I thought the brown patches may be 'corking' but there are marks the whole way up the cactus.
Any advice greatly appreciated!
