For those of you who grow from seeds, what have you found to be the best topping to stop moss/algae growing on slow germinating seedlings?

    Generally if they're tough perennials horticultural grit is your best option.
    When I sow petunias etc I use just a thin topping of vermiculite

    Thanks Pete8................when do you start your petunias?

    I sowed them on 3rd March this year in my propagator, but made  a note that it was too early as by 24 April they were starting to flower and very rootbound, and we were still getting frosts, so next year I'll be starting them 2 weeks later

    I use vermiculite for all my seeds on the top.
