Translucency ..the sign of Echeveria Agavoides root rot !

I don't like posting about negatives, but if you can learn from it, then its going to make you a better and more observant gardener.

Here was my prized seedling of a red edged Agavoides that was before the recent monsoon of rain, it was romping away with good growth.

Now after spotting signs off it being over watered I thought maybe we could save it, but alas as you can see from the colouring once it turned that translucent colour in the leaves, its a goner unfortunately !

So it begs the question, how do you recreate the ideal conditions of a Echeveria from Mexico to withstand the english climate?  For us soil for plant means growth, but if the plant in it's native habitat it grows on a rocky outcrop it will not enjoy literally drowning in a pot. 

Looking at the internet literally had me spinning in a circle, so many opinions but no firm answer. My recent import from Germany arrived in just pumice and lava rock, no soil at all. But I've also had bought plants in soil, dry soil mind you, but soil never the less.

With that in mind the experiment is to provide a fast drainage system, whilst lightly drenching th roots and providing minerals from the substrate to feed the plant.  

Easy eh ? No, but I'll find a suitable potting compost one day!

So disappointed to lose this one, as one of a kind. I'm hope the nursery grower has some more seedlings in the future.
