I'm going to buy a few lavander plants to put in big pots in my front
(North facing) garden in Brixton. What sort of compost should I put
them in? On the one hand, I want to be nice to them. but on the other,
I associate them with pretty rough garrigue landscapes.

What's more, they'll have to surive several weeks in August without me
there to water them.
