Hi

I had been given a small courgette plant in a pot which I have been growing on my kitchen window over the weekend. It was growing leaves at a rapid rate and so I decided yesterday to plant it out in the garden.. In terms of the ground outside, our soil is very stony, hard and clay like. So I dug a trench about half a foot deep and then filled the trench with multi purpose compost. I watered the compost and I then planted it in the middle of this compost and put some slug pellets around, I then watered it again last thing at night..
However, since I planted it out, it doesn't seem to have grown at all, have I done something wrong!
How quickly should it grow and produce folwers and courgettes?
Any help would be welcomed!..
