Hmm 🤔 it doesn’t seem to mention anywhere the sort of conditions the seedlings are going to need post pricking out and then potting on etc. ... if I had a heated greenhouse I’d be sowing them now, but with only windowsills and a mini-greenhouse against the house wall I think I’d better wait a while ... I simply won’t have the space they’ll need to grow on.

I sow chillies and peppers 1st week in March and I get a huge crop by summer. I don't grow petunias any more, but when I did, I also sowed 1st week in March and they always performed well. As Dove says - it's easy enough to get them to germinate, but at this time of year - then what?

I don't grow petunias but I do start my chilli plants, usually by the end of the month so not quite yet. They can take a while to germinate (I have a small heated propagator for the windowsill) and they also grow quite slowly - the sort I grow anyway - so they are still quite manageable sized plants on the windowsill by the time it's warm enough to put them in the polytunnel in May. I only usually grow 2 or 3 plants. I do it because the propagator is tiny and I need it for the greenhouse tomatoes to start them off in March, so the chilli plants need to be big enough by then to grow without heat.
I guess it depends what you have room for. I've not had a problem with leggy chilli plants.

I don't grow petunias, my favourite time for chillies with windowsills only is mid-February. But I would do them sooner if I had a heated greenhouse or a conservatory, and I would also do sooner varieties that need longer season (chinense and others super hot). Another crop that I sow very early is aubergines, they need even more time than chillies. We have very mild summers and my greenhouse doesn't get too hot. Everything takes ages to ripen. And I used to grow them without a greenhouse.
