Plant hyacinth bulbs 6” deep. Space 5 to 6” apart (grape hyacinths can be 2” apart). At the northern limits of their hardiness (USDA Zone 3), plant 1 to 2 inches deeper to ensure winter hardiness.If you wish to plant 5 or more bulbs at the same time, dig out a larger area. Hyacinths look beautiful in groupings of 5 to 9 bulbs. Grape hyacinths also look best in masses and loose drifts.Set the bulb in the hole with the pointy end up.After planting and covering with soil, water thoroughly.Apply a 1-to-2-inch layer of mulch around the plants to discourage weeds and disease.If you are transplanting, water sparingly and then do not water again until flower buds appear the following year.Warning: Hyacinth bulbs (and daffodil bulbs) contain a substance called oxalic acid, which can be irritating to bare skin. Use gloves when handling these bulbs for extended periods.
