I'm an enthusiastic gardener each spring but when nothing grown, except weeds, I lose heart each summer. Nevertheless, I've sown veg seeds again this year: carrots, parsnips, spring onions, cabbage, etc - and I've diligently watered them daily and I have some incredible bindweed this year but not much else.

As a Londoner with limited garden space I felt inspired when I heard about the One Pot Pledge which is a campaign to get us to grow our own food in a garden pot.  It’s a scheme for gardening newcomers and I'll still count myself in that category after 15+ years of failed growing. They hope to attract 30,000 people to try the idea (why this number, I don't know) but I've signed up and my One Pot Pledge membership number is 1315.

I had already bought some seed potatoes and have heard that children grow potatoes in buckets so that's where I've planted mine, in organic compost, of course. And I've added the bucket to my daily watering regime. I probably should have checked the One Pot Pledge potato growing tips but my enthusiasm got the better of me. For now it's wait and water time.

The One Pot Pledge has lots of growing tips so why not sign up too?

Of course, if nothing grows again this year I'm resort to growing cress on the windowsill which, I feel, is best grown in an old egg shell with a damp ball of cotton wool inside sprinkled with cress seeds and a face drawn on the front. Do you think that would count towards the One Pot Pledge?
