I swear by John Inns seed compost with permiculate to lighten the texture and improve drainage. I use John Inns no 1,2,3 as I pot up and also add a little fish\bone\blood to the mix. If you have enough of your own homemade compost, leaf mould or mushroom compost (if you can source it) you can make your own seed mix. If your using multi purpose then I would add permiculate and fish\bone\blood to improve its texture and nuritents. I really noticed the difference for the better when using John Inns seed compost over general purpose, so if you can afford it I would recommend using this. |
