just to let folks know that marshalls seeds are giving away vegetable seed growing guides with orders
http://www.marshalls-seeds.co.uk/
I had one similar to these given years ago and it is very handy, made out of durable plastic, rotating and all information about sowing conditions, spacings, crop rotation, times of year, when to harvest for 40 veg (does include melons and toms) and a conversion chart as well
you might want to check it out :) make nice gifts
