Hi Peachguy!! You will find organic recipes spread out all over the forum, but I can direct you to the largest pockets of them. In the Rose Care Forum, the first thread, dated March 19 called Organic Rose Care has several recipes. These recipes are not just good for roses but for any plants. Also in the Rose Care Forum, there is Mildew and Blackspot Spray on May 7, and Goodies for Roses on April 13.
In the Organics Forum, you will find a thread called Home Made Fish Fertilizer on May 11, and Compost Teas on May 5.
Hopefully these help you out with what you need. If you still need helpl, just drop us a line, and we'll be here!
