Re: Pale recessed patches on Trichocereus pachanoi

I think I have found the cause, and they've even started healing/looking normal again. Turns out it was a lack of water, combined with possible sun damage. They were weekly watered yesterday and within a few hours the sunken areas had levelled out and the colour began returning to green from white/y...
