Hi Jools,
No beds, just concrete. I was worried about the soil too!
I will be growing lots of flowers too. What I know about growing them you could write on the back of a postage stamp. I've promised my children that there will be lots of different flowers. No harm in planting a few lettuces in between! Last year we had a competition on whose tomato plant got the first red tom and my 8 year old son won even though he did very litle and my daughter (11) nutured hers. My winter hobby is card making so I've also been fund raising for their school!
I'm really looking forward to propagating plants in the greenhouse (once I've learnt how). We live very near to Wisley RHS and they run some great courses so will be booking on one or two to learn all about fruit trees and soft fruit. I've ordered several trees from Browns so it would be useful to know how to prune them etc. Are you growing any fruit?
