ok John gel it is then I also found looking through my garden diary some advise I was been given by a gardener the grows his brassicas for veg shows and its as follows
1 obviously after cultivation of the ground make a hole with a dibber
2 get some baby pampers break them up into pieces and soak them well in water and liquid fertilizer mix
3 put the wet piece of pamper down the hole and plant the in this case a cauliflower plant and cover
I've never tried this method myself but the chap who told me this seems to win quite a few prizes
with his brassicas anyway I'm just passing this info on to all who would ike to give it a go
