Bone meal is good food for most bulbs, but I always mix it into the soil. I can't see why the concentrated bone meal would hurt the bulbs, but I can't be sure. I would check a few bulbs and see if they are making roots. If not, or if they are rotting, you are in trouble.

There is a theory that bone meal doesn't really work. I've grown lily seedlings with and without bone meal. It works, wonderfully. Root growth and bulb development are vastly improved. Just ignore the cynics, and they will get bored and go away.

I don't use bonemeal because it attracts my dog to the gardens. I use an all purpose fertilier (slow release) in the spring, milorganite once a month in the summer and spray with water soluble fertilizer every other week with which I add immucloprid (Merit) to control the red lily beetle. I fertilize well with Milorganite at the end of the season. I use Milorganite because the daylilies love it and it's just easier to use the same thing for everything. BTW, newly planted bulbs should not need to be fertilized but I try to water in with root stimulant mixed with the water.

mainiac, the Milorganite analysis looks good for bulbs; not real strong in phosphorus, but it has iron, which I find is very helpful to many plants, especially acid-lovers. And the nitrogen is slow-release. But it doesn't have any potassium; that's a problem, unless you have potassium-rich soil. I probably wouldn't use it on edibles, because of the risk of heavy metal contamination.

I'm going to stick with bone meal because I have side-by-side experimental results that prove that is very effective on lilies, daffs, and tulips. Lily seedlings love it.

Thwe primary reason I started using Milorganite is because it deters deer. It used to be an annual event when the deer showed up to eat the lily buds. Since I started using Milorganite they don't bother the lilies anymore.

How about Bone Meal for Calais Lilies?
