Dear All, A number of years ago Diana Chapman recommended tomato fertilizer as an excellent source of fertilizer for bulbs. I believe she mentioned a ratio of 5-10-10. Others have continued to repeat this advice. I began to look for tomato fertilizer and never found any in the ratio she recommended. I found huge variations in the ingredients of what was referred to as tomato fertilizer. They were not all low in nitrogen. If Diana and I both live in California and there is this huge difference just in our state, think how that could be magnified around the world. I'm not sure what would be the best common denominator when explaining what to look for. Is the ratio of Nitrogen-Phosphorus-Potassium everywhere? Mary Sue
