Agapanthus Propagation

Torg22Torg22 Posts: 302

Hi, I have read that when you sow agapanthus seeds you should cover the soil with sharp grit. Is this to retain moisture or is it to deter snail/slugs etc...? Would covering the container with cling film work?

I was thinking of collecting some seeds tonight and sowing them. I also have some seeds given to me by my mother in law but the seeds are now a year old I would imagine. Will I have any success with the older seeds as I have heard that you should sow fresh seeds.

    Cling film will trap moisture and probably lead to rotting.

    I sowed seeds a few years ago and just used compost to cover them.   Got lots of babies.

    The only way you'll find out if yours are still viable is to sow and wait and see.

    Once the seeds are potted up in a tray, would you advise me to leave it outside in the elements or place it in the mini greenhouse??  If inside the greenhouse will it need watering regularly?

    I thought agapanthus was half hardy but my neighbour gave me some from her garden which had self seeded.  We are in Llandudno where we get little frost and no snow.

  • have had agapanthus in the ground for 15+ years and now the large ones hardly bloom at all (the peter pans bloom a lot).  I live on the coast in California where we're in a drought, but why does the small variety still bloom, but not the large ones?

    I've sown agapanthus seeds the last two years.  I put them on top of compost with a light covering of compost on top and have them on the window sill in the kitchen over the winter.  I move them out when all risk of frost has passed and pot them up, with 3 seedlings per 9cm pot (purely because I get so many I'm trying to save space and cold frame will only take so many pots).
    Once their roots are coming out the bottom I move them onto a 1 litre pot and then a year later onto a 2litre pot.  (by the time they go into a 1 litre pot it is one plant per pot)

    Planted my first lot out this summer and have another batch in the cold frame for this winter and it may be the year after next before those get planted out.

    My first lot are growing really well in the ground so hoping for some flowers next year.
