Choosing and Preparing a Planting Site For the largest blooms and straightest stems, choose a site that gets full sun. The bulbs are tolerant of partial shade as well. Grow in loosened, moderately fertile soil that drains well. Avoid low areas where water collects; hyacinths will rot in wet soil. Before planting, loosen the soil and work in 2 to 4 inches of compost or bonemeal for fertility.
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 hyacinth 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-toinch 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. Forcing Hyacinth Bulbs Indoors Hyacinth bulbs may be forced into early growth for indoor display in the winter.
Plant them with the tips just showing, in soil-based potting mix in containers with drainage holes. When shoots are about 1 inch long, increase light and temperature gradually. Water carefully, avoiding wetting the shoots or waterlogging the soil. Soil should be moist, not wet. After flowering, forced hyacinths may be transplanted to the garden and they will flower again in subsequent years.
If it is dry at that depth, it is time to water. Water deeply at soil level, not from overhead or with a sprinkler which encourages disease. Lay the hose end next to the plant, turn the hose on low and water for about 30 minutes or until the soil is moist. A soaker hose turned on low for a few hours will cover a larger area effectively.
With the organic matter and mulch, you do not need to fertilize. Protect container-grown plants from excessive winter moisture by keeping them covered or moving them to a sheltered area. Bulbs are prone to gray mold and bulb rot when kept too wet.
At the end of the spring season, the foliage will die back naturally. Remove when the leaves have turned brown to help prevent fungal diseases.
Hyacinth bulbs can remain in the ground throughout the year in most planting zones. Hyacinths require a period of colder weather to bloom.
Indoors Hyacinth bulbs that have finished flowering indoors can be transplanted to the garden. After their foliage dies back outdoors, hyacinth bulbs can be brought indoors and stored in a cool, dark, dry place until the fall or winter.

What do you want to read next? Planting Fall Bulbs for Spring Bulbs store energy within themselves, and therefore only require minimal fertilization. For the most robust hyacinths apply a slow-release fertilizer made for bulbs when you see the leaves emerging in spring. While the hyacinths are blooming they should not require additional water, other than what is provided by the earth. However, if you are facing a rather hot and dry spell in spring while the hyacinths are blooming a light water will help the blooms last longer.
When hyacinths are done blooming you can remove the flower stems. It is best to keep the leaves intact until they can be removed from the ground. Whether you are planting hyacinths this fall outside or forcing them for indoor blooms they will add fragrance to your home. Hyacinths can be grown in bunches or in rows in your garden or in vases and pots in your home.
