Q.How To Use Vermiculite In A Newly Planted Choisya
I’m moving the choisya into a large planter and would like to know how much vermiculite I should add to the multi purpose compost. Please advise. Many thanks.

They need well-draining, acidic soil, so I would add perlite instead of vermiculite. Vermiculite holds in moisture. You can make your mixture about 1/3 perlite.
