Help: Consolea rubescens has brown patches/damaged skin!

[tashipetter]

Hello all,

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!

Best wishes,
