What is the correct fertilizer to use for bulbs?
A. If the bulbs are to be sited in slightly infertile soil, you might add some bulb booster or bone meal on top of the soil after planting. These products have a higher proportion of phosphorus, which is necessary for optimum root development. An alternative would be to sprinkle a 5-10-5 or 10-10-10 fertilizer around the site in spring as the leaves are emerging and then again in fall. Always water in granular fertilizers.
