I've never been very good with seeds (other than self seeding plants!) but I need to do something about that to make up for not going to garden centres (DH needs to be careful). This year I had mixed results with what should be easy ones - nasturtiums were great, some of the sunflowers were good but only a few got to maturity; sweet peas and cosmos I thought I'd done in time but some have never made it to flowering.
I don't have a greenhouse or anywhere to put one (sloping garden.). I'm wondering if cloches or something would be helpful but I don't have much hard standing. Limited space indoors - the windowsill I can normally use has student DDs houseplants on it, and my kitchen table is already somewhat occupied with herbs.
