avapalo how big is your plot and how much time do you have and also how much experience have you got?
It was hard for me at the beginning because
a) didn't have much time
b) had a huge plot
c) didn't know my weeds from my beans
I made it harder by getting help turning over the soil, allowing other people to dig the roots in for me. Not a good idea.
But if I had the time, a small plot and was an experienced gardener, I would go the organic way.
Semtex - werks for me!
