I love mesembryanthemum and for two years I've tried to grow my own.  They germinate readily enough, in a tray of coir on the kitchen windowsill.  But they're so fiddly to transplant, I'm sure I must be damaging the roots.  I transplant them into yogurt pots of coir, put them in the cold frame, keep them fed and watered, but they don't grow, they merely survive!  Any tips?

    John Innes seed compost might be better for them - they don't like being wet. They also need sun and warmth.

    Coir is just coconut fibres. It contains no nutrients or trace minerals.
    When your seedlings first emerge they will need feeding with a coir specific feed once they are about 4 days old and will need to be fed every few days from then on.
    I wouldn't use coir for that purpose.

    If I sow petunias/begonias etc (minute seed) I fill a pot with ordinary seed compost, level the top a little, sprinkle the seed on then cover with a sprinkling of some vermiculite dust (at the bottom of the bag) and spray with water from a hand sprayer and pop it in my propagator - or cover with a plastic bag and leave somewhere warm and not in direct sunlight

    Wisdom is not putting it in a fruit salad.
