The only thing I've sown outside is Broad Beans, but I also have some in pots in the tunnel, and another variety to sow in pots. It's partly that all is frozen solid here and we expect plenty more, but also because the ground isn't prepared adequately yet. I will sow some suspended lengths of guttering with peas this week, in the tunnel. Also early carrots in containers. I have beetroot in modules which haven't germinated yet.
In my heated propagator

I have tomatoes, chillies, cucumber, aubergine, butternut squash (which I sow earlier than other squash types) and various flowers, and on the window sills I have lots of different lettuce, some herbs and more flowers. The herbs and the butternut haven't come up yet, and the chillies are being sporadic but most things are up and at the seed leaf stage.
I had real problems last year and the year before with pyralid (weedkiller) residue in the seed compost I bought in (deformed tomatoes and no bean crop) so this time I am trying my own home made composts, using molehill soil, seaweed meal, sieved garden compost or FYM (depending on the amount of nutrition I need), a bit of wood ash and

some peat. I haven't touched peat for years because of the environmental impact of extraction, but I have no leafmould so I've decided that the tiny amount of peat I am using doesn't compare with running a power station on it and will make the difference between me getting crops and not. If only we had some fallen leaves I could make leafmould for next year.......
