I'm assuming you are not going to use Chemical fertilisers or weed-killer, the cost will far negate the savings you are going to make growing your own. The Cottagers didn't use chemicals !!
The only sure way to know you are eating chemical free fruit and vegetables is to grow your own, If the area is water logged you will need to sort it out before you dig it over.
If you are planning to turn a lawn into a planting area for fruit and veg, you will need to remove the turf, the easiest way is to cover the area with black plastic until the grass rots.
A quick way is to remove the turf with a spade, mark out squares about 2" deep with a sharp spade and scoop the turf off, turn it over and store in a heap in a corner of your garden to turn into loam to be added back to your garden.
Digging the ground
Dig the area over removing as many large stones and weeds as you can, don't try to remove every stone, its impossible.
Providing the soil breaks up into reasonably small chunks there is no need to rake it over. Weeds that haven't gone to seed can be added to your compost heap. Weeds that have gone to seed like Bindweed and ivy can be rotted down in a plastic bag and then added to the compost heap.
Sandy soil is easier to dig but doesn't have as many of the essential nutrients clay soil does so you will need to dig in plenty of compost making compost
Chalky soils are dry, stony and low in nutrient, but by choosing plants that grow in chalky soil you can still grow a good selection.

For organically-grown plants choose a gardeners shop that clearly labels organic plants. The best way if you can, is to buy organic seeds and grow your own plants from seed.
If you are sourcing your plants from a garden center be aware that the plants grown for sale in the large modern garden centers will be grown using chemical fertilizers and pesticides and as well as bringing some of these chemicals into your garden the plants will be addicted to the chemicals and may show signs of stress for a while as they are weaned off.
Also check the plants and the root system for signs of insect or disease problems. If the plant looks straggly and weak, put it back even if its reduced in price. Only introduce strong healthy plants into a chemical free Organic garden.
These vegetables are easy to grow with just basic care.
To prevent disease its a good ideal to rotate your vegetables and not grow the same crops in the same place year after year.
Collect any seeds from the plants that go to seed for next years harvest

Daily Telegraph research found that a
basket of six fruit and five vegetables from Tesco and Sainsbury's costs £37.20, compared to just £21.01 on average from four different independent greengrocers around the
country. Why pay £16 more for a basket of six fruit and five vegetables, plus the cost of driving to the supermarket. Keep it simple and shop locally.
We throw our hands in the air every time our local Butchers, Bakers, Greengrocers and Post office gives up the battle with the supermarket, but don't support them when they are open, preferring to buy and eat fruit and veg that has gone around the world twice, instead of buying local produce that is on average, £16 cheaper for a basket of six fruit and five vegetables.We let supermarkets get away with charging far more for fruit and veg than they should.
