What type of compost do nasturtiums flower best in?
I have some young nasturtiums grown recently from seeds which are in 10cm pots of John Innes no 1 compost. In previous years I have failed with them rather becasue I have tried to grow them with too high a fertility level. Consequently they made mostly leaves and only a few flowers throughout the summer. I wish to grow them in pots on my patio. When I move them on into bigger pots, which I must do soon, what type of compost would work best to use? Should I stick with John Innes no 1 throughout the whole season and never add any fertilizer or feed, or would something else work better? I'm really keen and determined to succeed with them this year. Please can anyone help?
