First work Bone Meal or Bulb Booster into the soil where bulbs are to be planted.   Then, plant as directed:  larger bulbs such as tulips, daffodils and hyacinths should be planted 6-8″ deep and 6-8″ apart.  Minor bulbs such as crocus, snowdrops, anemones and others should be planted at least 4-5″ deep and 4″ apart.  Remember, the pointed side of the bulb always goes up.
