I tried to grow an organic garden last year but had no luck, all that happened was bugs eating my food.
Growing organically for the home gardener is very achievable. Your local nurseries will most likely be your best source of organic fertilizers, insecticides and fungicides.
All food is organic, take my word for it. Many seasoned farmers cannot grow organic per govt limits. Organic is a political term not a agricultural term. If you want to be organic you will fail more often than not. I use whatever is necessary to ensure I get a crop that I can eat. Captain Jacks Dead Bug Brew is as organic as I can get. If you insist upon being strictly organic then you will have very little to show for your efforts. Nature is way stronger than you.
You can put chemical free pest spray on your plants.. works like a charm for me. There was one bottle i found in my local garden shop that repelled over 120 different bugs and weeds, it was expensive, but it worked!
Use flour instead of the product called SEVEN. It gums up the mouths of the bugs, they don't like it. Plant peppermint around your house and chicken coup. Rodents and Raccoons don;t like it. Shred orange peelings where you don't want your cats in the garden, the cats don't like the smell. Use cinnamon where the ants take residence. It won't kill them but it will make them want to move to another location. Sprinkle hot pepper powder where bugs are eating your plants. Wash egg shells. Let them dry out well as they break into pieces better when they are dry. Sprinkle it around your vegetable plants. They don't like crawling over the sharp edges to eat your plants. Ad compost to your garden soil. Compost is made from vegetable scraps like potato peelings, old pieces of lettuce etc... It breaks down and turns into soil. Manure is used but some contain pesticides that are causing leaves to curl funny and causing problems with growing vegetables. It depends on what the farmers use in the fields, or what the neighbors are doing with garden products, pesticides etc...may play a factor. The word organic is over used but I do understand what you mean. The government has such regulations on organic that they look at like a five mile radius and specific time frames before allowing farmers to sell there food as organic. If your neighbor is growing genetically modified seed in there garden, cross pollination with your veggies is a possibility. Organic by government standards means smaller vegetable production and less crop.
