How to Grow Hyacinth

One of the loveliest scents of spring comes from hyacinths in blooms. Even at a distance, you'll notice these flowers' intense fragrance and spikes of bright colors. Introduced to Europe during the 16th century, hyacinth's popularity sparked Dutch bulb growers to breed more than 2,000 cultivars by the 18th century, and today there are about 60 to choose from in commercial cultivation.

Modern hyacinths are some of the easiest-to-grow spring bulbs—they can be planted in the ground or pots, or grown in water in a bulb vase, no soil required. Hyacinths are best planted in early fall and will grow slowly, emerging as shoots in the spring.

Hyacinth Care

For the strongest and farthest-reaching scent, grow hyacinth in large blocks. Hyacinths also mix well with other spring-blooming bulbs, since they come in so many colors and sizes—their spiky flower stalks make a nice counterpoint to cup-shaped tulips and ruffled daffodils.

Most varieties of hyacinth bulbs are fairly large. For spring garden blooms, plant hyacinth bulbs in the fall six to eight weeks before the first frost. They should be placed root-end-down (widest side), about 4 inches deep. Give them some room to spread out by spacing them about 3 to 4 inches apart. Cover with soil, and water well.

There are taller varietals that can tend to flop—you can stake them if you only have a few, or plant them closer together so that they support one another. Once the bulbs have finished blooming, cut off the flower stalks (leave the leaves) to encourage the plants to store energy in their bulbs.

Light

Plant your hyacinth bulbs in a spot that boasts full sun or partial shade. As with all spring bulbs, hyacinths sprout, bloom, and start to fade into dormancy before deciduous trees fully leaf out, so you don't have to worry about too much shade from nearby trees. You should aim to give the plants at least six to eight hours of sunlight a day.

Soil

Hyacinth bulbs are not particular about soil pH, but they do best in soil that is loose and well-drained and will not tolerate wet soils. Rich soil can lead to floppy stalks, so go easy on the organic matter when preparing or amending the soil. 

Water

Water the ground well after you plant the bulbs. Continue watering into winter if there is no regular rain, but allow the ground to dry out between watering. If the bulbs sit in cool, wet soil, they will eventually rot.

Temperature and Humidity

Hyacinth can be expected to survive the winter in USDA plant hardiness zones four through eight. They may need some winter protection in zones lower than four, and some pre-chilling in zones above eight, depending on the variety. Dig up the bulbs where winter temperatures remain above 60 degrees Fahrenheit and chill them somewhere dark and cold for six to 10 weeks. Unfortunately, hyacinth bulbs are short-lived and will probably last only three or four years. Many people treat them as tender perennials and replace them yearly due to decline.

Fertilizer

The easiest way to feed new bulbs is to toss some bulb food into the hole at planting time. There are many fertilizers available for feeding bulbs, or you can use an ordinary bone meal. Feed the bulbs at planting and again in the spring when the new growth first appears by scratching some bulb food into the nearby soil and watering well.

Propagating Hyacinths

Hyacinth bulbs don't usually live for more than about three or four years. If you'd like to propagate more hyacinth bulbs, wait until late summer and gently lift the bulbs. Remove the small offsets forming around the edges of the bulbs, and replant everything, including the original bulbs. Be patient, because it will take a few years for the offsets to bloom. Since the plants can disappear in mid-summer, mark their locations while they're still in bloom.

Potting and Repotting Hyacinths

When planting in pots, hyacinth bulbs can be spaced more closely than when planting in the ground because the bulbs won't need room to multiply. You can squeeze them in so they are almost touching, but leave room for some soil in between to hold water.

Keep the soil damp but not soaking wet until the bulbs sprout. Then, water whenever the soil dries out. Once the bulbs have sprouted, move them to indirect sunlight. Cool temperatures will keep them in bloom longer.

If you are potting hyacinth indoors for forcing early blooms, you will either need to purchase pre-chilled bulbs or pre-chill them yourself.

Common Pests/Diseases

All kinds of rodents will munch on hyacinth bulbs. You can protect them somewhat by throwing a handful of gravel into the planting hole, or you can try commercial rodent deterrents. An easier method is to interplant them with daffodils, which rodents tend to avoid.
