Here is his reply. ------------------------------------------- < snip > ------------------------------------------------------------------------------------------------- Thank you for your mail. Bulbs like all plants are best fed with a complete plant food rather than a single ingredient. We produce a product called Bulb-tone that will provide all major, minor, and trace nutrients required. A fact sheet is attached. Sulfate of potash (SOP) is a mined mineral with an analysis of 0-0-50. It is generally considered an acceptable input for organic gardening and agriculture. It is superior to the muriate because it is lower in salts that can harm plants (particularly tender emerging roots of bulbs). We no longer produce the SOP as a single ingredient. We do use the material as a potassium source in our blended plant foods. We do have the muriate, but plan to discontinue that as well. ------------------------------------------------- <snip>-------------------------------------------------------- Judy, the ever-curious in New Jersey
