Question: Please let me know what I can use on my roses for fertilizer and soil conditioner and I do not see how to order grass fertilizer. Thank you, Joan. Answer: Joan, A fantastic combination for roses is OPTIMIZE-Soil Optimizer, MAXIMIZE-Microbes & Minerals, and NOURISH-Biosol--you'll be amazed by the results. We use out NOURISH-Biosol organic fertilizer for lawn and for vegetables and trees, plants, etc. It is the best fertilizer I have ever used and it not only will feed your grass, but it builds the soil in amazing ways at the same time. Best Regards, John
