For all of you blessed with a garden - or the ability to create a garden, should you want one - one of the best things we can do for our family and friends is to plant a vegetable garden and grow our own organic produce. In the mid 90s, I had set aside a huge space and proceeded to plant a vegetable garden that was about 40' x 50'. This garden produces so much food in such a short time, that I was handing bags of it away for free at the front door to anyone who showed up. Not only did we save a fortune in money from the produce department, but we were able to grow our food organically and it tasted great, was 2 to 4 times the size of grocery store vegetables, and just melted in your mouth. Happily, our friends and whomever happened upon our door, got free groceries at each visit, because the garden produced a ton of food constantly. I got to the point where I just kept bags outside the front door in the entranceway. "Please take one on your way out?" And they did.
Living in a condo, those days are gone now. But, if you can, do it. You will know exactly what is going into your food and you can choose non-GMO seeds that makes sure you are staying away from making frankenfood.
But also remember to mineralize your earth with the good stuff. For even with NPK, your vegetables and fruits won't have an abundance of minerals in them, which is what you want in the first place. You have to put them in the earth, before you plant.
