  • Sweet Peas misbehaving?

    About a month ago I sowed about 20+ sweet pea seeds..... and one has germinated.

    I'm a bit bemused, as I've never had a problem before. Usual conditions, good seed in its sow by date, good supplier... They've been on a cool windowsill, and after a week I popped one lot into the heated propagator, but the only one that germinated was outside this.

    Should I keep waiting or try again? What went wrong?

    They've always been foolproof for me.

    Have you had a gentle poke around in the compost to see whether they've rotted or not ?

      When mine have failed it's because they have rotted. These days I sow them very shallow - just barely covered - into compost that is moist but not soaking. Then I keep them cool but not cold until they germinate.

      In the past I've tried pre-soaking them and I've tried chipping bits off the coat. I don't think either of those made much difference.

      I would try again, if they were going to grow they probably would have by now. But no harm in a poke about first, see if you can diagnose the problem.

        Yes, I'd go with too wet as well, they certainly don't need any heat to germinate.
        I let the compost take up as much water as it wants, from standing in a tray - then don't water again until they're up.
        If they look as if they really are drying out, the most they get would be a light misting from a spray bottle.

          Thanks all. Will check them out and then try again.

            I chit all my sweet peas - it's the only way I can get them to grow. I put them in a clear sided lidded container on damp kitchen roll. This morning I threw out one lot that haven't chitted at all after 3 weeks. It was old seed though - sow by 2014. Everything dated sow by 2017+ is chitting, so for me, very old seed doesn't work.

            Endless wonder.

              I’m growing sweet peas for the first time. Sowed two types in my unheated greenhouse in mid Feb. One kind started coming through a few weeks ago but the other ones have been slower. Just starting to come through in the last few days. I just assumed they were a bit slow.
