I just stuck mine in a pile of horse poo and let them get on with it.

Worth a go..... Nothing ventured as they say. Thanks for this.

Do it before you sow the seeds!

  I grew marketmore ,like DD with chicken wire so they could grow up it ,some were in the
    greenhouse ( pots) and some outside (in the ground ).They both gave plenty of cuc's ,and
   was surprised how well the outdoor one's did considering the weather.

I don't grow outdoor ones as I am sure the weather isn't good enough?
The ones in the greenhouse are planted directly into the greenhouse border and as they grow, tied in to a contraption that OH built. A sort of indoor Munty Frame. Works well for me.

I grow them outside and im much further north than you. The ones i grew last year where really heavy croppers so im sure you wont have any problems considering your location
