Greenhouse

I have placed a cubic bag of grit sand to give a good 6ins to lay the flags on so I don't anTicipate a problem with drainage. I want to avoid the job of changing border soil every year. I'm lucky to have soil that drains quite well.

 

Spruce's suggestion of a flagged path with gravel borders is what I have, except I have patio pavers rather than flag stone. When it is really hot I wet down the gravel and pavers and let the evaporation cool the greenhouse. I don't know about others, but I find that just sitting in the greenhouse, reading or listening to music, is therapy for the soul.
