I have too many half used packets of vegetable seeds. I don't want to waste them, but nor do I want to waste my time preparing the soil and planting them if they're too old ever to germinate. I'm abandoning them for the moment.
I started today with the 'all-the-year-round cauliflower'. I can't be bothered to plant seeds with measured spaces between them, so I just scatter them into a pot, cover them with a bit more soil, and will transplant the best ones when they pop up.
If I keep it up, by February, I should have leeks, onions and parsnips under way too.
The instructions don't say anything about a greenhouse, but I'm assuming it will be frost-free, and that they should have a better chance in there than outside. Of course I'll have to water them, although the greenhouse seems permanently damp at this time of year, so that shouldn't be too much work.
