Different growing medium for pots

Andy LeedsAndy Leeds Posts: 518
Afternoon, I've got a couple of plants to put into pots, and was wondering what type of 'soil' I should fill the pots with.

Previously, the only things I've put in pots have been acid loving so I just filled with ericaceous compost. For other things, e.g. the Crocosmia lucifer, cordyline red star, choisya white dazzler and viburnum burkwoodii Anne Russell I have ready to put out, is it simply filling a pot with multipurpose compost; filling with the soil from the garden, a mix of both or something different?

As you can see, I'm really not afraid of asking the stupid questions image

    Good for you Andy - ask away - no one knows it all and if you don't ask you won't find out image

    For plants that are going to be in the container for more than one season I would use John Innes Loam-based compost No 3 - it will has a structure that will last and not break down to dust like ordinary MPC will do over time.  It also has the right nutrients to feed a mature plant for at least one season. 

    I would add a few handfuls of horticultural grit for the cordyline as it likes really well drained soil.

    Personally I wouldn't put the Viburnum burkwoodii into a container - it'll be much happier planted out into the garden - they grow into very large shrubs.

    Thanks for the reply - I think the viburnum will only be in for a year until I find a place for it image
