Do you mean bone meal? Bulb booster is a fancy name that they can charge more for. When planting any plant it is always wise to use bone meal to stimulate root growth.

Here is a link that might be useful: Propagating Perennials

I might add a word of caution about bone meal and furbabies (dogs). Years ago I planted lots of tulips, adding a bit of bone meal in each hole as I planted them. My doggies just were not happy until they had dug every one of them up...smelling the bone meal, I'm thinking.

If you are planting them in containers, then adding some sort of slow release fertilizer at planting is appropriate. Growing plants in containers is far different from growing them in the ground and the limited soil environment and constant water required to keep container plants happy leaches out nutrients that must be replaced. Rather than "bulb booster" or any limited ingredient type of fertilizer, I would use an all purpose type - something like Osmocote, which mixes easily in container soil. Even this is unlikely to provide ALL the nutrients necessary during a long summer growing season and you may need to supplement with some sort of liquid fertilizer as well.

btw, I have never found the need to use ANY fertilizer when planting most bulbs in the ground. Most fresh bulbs (true bulbs, that is) are self-contained growing units and have all the nutrients they need for healthy growth stored in the bulbs themselves. Once they have been planted for a season, adding fertilizer to the planting area when the foliage appears can help. Even mulching the area with compost in fall or early spring will provide what is necessary. We tend to over-fertilize most plants - it's the successful marketing campaigns of fertilizer manufacturers that have brainwashed us into believing it necessary. It is not.

Thanks everyone for your advice!
