Daydaisy you could get too caught up in this organic or not question.
If all you are adding to your compost heap from outside your plot is a few peelings from bought in fruit and veg then it's as close to organic as makes no difference.
The important thing is to garden as organically as possible yourself.
If you are not selling as organic then what the difference.
If you are happy that you have kept non organic practices to a minimum.
Strictly everything added to the veg plot must be organic for the finished product to be classed as organic.
Most of us use seeds that are not certified as organic to start with.
Here in my garden I use nets and fleece to leep off pests as much as possible but if you want a crop of Rooster spuds then a blight spray is a neccessary evil.
