There is an organic gardening supply store in Fayeteville that DH and I have been driving up to for the last few years. It occurred to me this time to ask if they have a web site. And they do. www.gardeniq.com or nitron.com. The name is Nitron Industries, Inc. They carry all kinds of organic fertilizers, mulches, seeds, sprays, dusts. We used Neem oil to get an outstanding peach crop last year. Also sprayed the pear with the fire blight spray. Buy Diatomaceous earth, kelp meal and fish emulsion from them.
