Cheap bird food sunflower seeds work perfect
Years ago when my kids were little we used the ones from hamster food successfully. This year is the first year in years I've grown them. Planting seeds from poundstretcher I got reduced end of season last year. Any spare I don't use will be repotted and stuck in a tray for others to help themselves to for their kids for something to do.
I bought some sunflower seeds from eBay but they never propagated so I decided to try the bird food ones. They started showing up after a couple of days.
You have to pay £2 when you can buy seeds cheaper else where. If we all spend £2 elsewhere on sunflower seeds, we will be able to grow more sunflowers
Waste of money. Buy a bag of bird feed containing sunflower seeds and use them. You can grow your flowers and feed the birds. I've got a couple of dozen sunflowers starting to grow from these seeds.
