Seed Saving

After work tonight, my little girl and I went to collect seeds in the veg garden from some of the flowers that I grew this year. 

There's three main flowers I grow, these are nasturtiums, marigolds and sunflowers (all have an ediable element but look pretty). Saving seeds from nasturtiums and marigolds is easy, even my 21 month old could manage that, but when I've tried to dry a sunflower head for seed in the past they've always gone mouldy.
I was wondering if anyone had any tips on collecting/harvesting sunflower seeds and drying them so they could be used for planting next year or just stored for cooking and eating?

Lots of Planting

With the greenhouse now glazed I've been getting on with some serious planting this and last weekend as I'm a little behind.

Marigolds always germinate really well

Firstly I potted on all my tomatoes - this is a job long overdue but they weren't as root bound as I thought they'd be.

I also planted sweetcorn, sunflowers (inside and out), marigolds, sprouts, purple sprouting, cabbage, runner beans, french beans. I pretty much filled every pot I could find. I also put in another row of carrots and some peas outside but my beetroot hasn't come up get (or more likely the slugs have had it).

Some weeds are also starting to make an appearance so I'll have to get the hoe out tomorrow!

Are you on target with your veg planting this year?
