prepare the grounf for planting

Hi
What is the best way to prepare the ground to grow sunflowers, should you use manure.
Many thanks
Happy New Year and a great allotment year

I do, where possible, a trench with a layer of muck in it. The trick for the real giants is not to give the roots a check by leaving them in the pots too long... sometimes I get it right, usually I don't...
