Planting, Growing, and Caring for Hyacinths

Catherine Boeckmann

Ahhh! The scent of hyacinth is intoxicating in springtime! And who can resist the tiny blue Muscari? Learn more about planting these spring-flowering bulbs as well as caring for the pretty pastel flowers after they bloom.

About Hyacinths and Grape Hyacinths

  • Hyacinths (Hyacinthus): Originally a pale blue or violet flower, hyacinths now come in a rainbow of colors, including lilacs, pinks, white, cobalt blue, cream, apricot, and even a blood-red hue. Each hyacinth bulb generally produces one flower stalk that stands 8 to 10 inches tall. The hyacinth鈥檚 loose-to-dense racemes (clusters) of strongly fragrant flowers may be closely packed single or double flowers.

  • Grape hyacinths (Muscari) are not directly related to true hyacinths, but also bloom in mid-spring and have the same care requirements. This tiny wonder has small clusters of bell-shaped, cobalt-blue flowers.

Note: This page will refer to both Hyacinthus and Muscari plants as 鈥渉yacinths鈥 for simplicity鈥檚 sake!

As hyacinths are one of the first blooms, they look best at the front of a perennial garden, near the front door, along a walkway, or in mixed borders. These beauties are also a great choice for pots and planters. Hyacinths make wonderful cutting flowers, too, and look stunning in bouquets. As the flowers are famous for their fragrance, you can bring the sweet scent of spring inside!

The Victorians revered hyacinths for their sweet, lingering fragrance, and carefully massed them in low beds, planting them in rows of one color each. In general, hyacinths are said to symbolize playfulness, sport, and rashness, though their meanings are color-dependent. Learn more about the meanings of flowers.

Please note: Most hyacinths grow in zones 3 to 9. They must have cold temperatures of 40掳 to 45掳F (4掳 to 7掳C) for at least 12 to 14 weeks. If temperatures in your area do not get this cold, you鈥檒l need to pre-chill the bulbs in a refrigerator before planting them outdoors. 

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.

Planting

Choose a planting site that gets full sun for the largest blooms and straightest stems. The bulbs are tolerant of partial shade as well.

Grow in loosened, moderately fertile soil that drains well. Avoid planting 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.

When to Plant Hyacinths

  • Like other spring-blooming bulbs, plant hyacinth bulbs in mid-to-late autumn, any time after your first fall frost and before the ground freezes.

How to Plant Hyacinths

  • Plant hyacinth bulbs 4 to 5 inches deep. Space bulbs 5 to 6 inches apart (grape hyacinths can be 2 inches apart). At the northern limits of their hardiness (USDA Zone 3), plant 1 to 2 inches deeper to ensure winter hardiness.
  • Dig out a larger area if you wish to plant five or more bulbs simultaneously. Hyacinths look beautiful in groupings of five to nine 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.

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.
  • Keep in a dark place at temperatures above freezing but no higher than 45掳F (7掳C), for at least ten weeks to allow roots to develop.
  • 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 into the garden, and they will flower again in subsequent years.

Growing

Caring for Hyacinths

  • Do NOT overwater hyacinth. They do not like standing water or having 鈥渨et feet.鈥 Water ONLY if the soil is dry at a depth of 3 inches. If it is dry at that depth, it is time to water.  
  • Water deeply at the 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. However, it’s OK to sprinkle a commercial organic fertilizer over the soil. 
  • Protect container-grown plants from excessive winter moisture by covering them or moving them to a sheltered area.

Types

  • Hyacinth orientalis 鈥Blue Jacket鈥: One of the great blues of the flower world. These award-winning hyacinths display big columns of royal blue florets with crisp white edges. 
  • H. orientalis 鈥楥ity of Haarlem鈥: A wonderful heirloom variety that’s been popular since the late 1800s. The flowers are soft, primrose yellow, maturing to creamy white.
  • H. orientalis 鈥楪ypsy Queen鈥: 鈥楪ypsy Queen鈥 is an heirloom hyacinth with salmon pink petals with peach and buttery-yellow highlights.
  • H. orientalis 鈥楯an Bos’: Intensely fragrant, this award-winning hyacinth has fuschia-pink florets that are tightly packed into large flowerheads.
  • H. orientalis 鈥Miss Saigon鈥: With a deep, rich purple color, this fragrant hyacinth is covered with starry, violet florets. Gorgeous!
  • H. orientalis 鈥楶ink Pearl鈥: Rose-pink flower heads turn heads with their cotton-candy sweetness; 鈥楶ink Pearl鈥 is a favorite for spring containers to add a pop of color.
  • Muscari armeniacum: This grape hyacinth has small and delicate cobalt-blue flowers that look gorgeous when planted en masse.

Harvesting

What to Do With Hyacinths After Flowering

Outdoors

  • After your hyacinths have finished flowering, remove the blooms, but don’t remove the foliage. The bulbs need their leaves to gather energy for next year’s blooms. The foliage will die back naturally at the end of the spring season. 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. If you live a warm climate where temperatures do not get below 60掳F, bulbs should be dug up in the fall and refrigerated in a cool, dry area for 6 to 8 weeks. Hyacinths require a period of colder weather to bloom. 

Indoors

  • Hyacinth bulbs that have finished flowering indoors can be transplanted into the garden. After flowering, they need time to gather energy for next year’s blooms, so they should not be placed directly into storage. 
  • 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.

Wit and Wisdom

Are Hyacinth Bulbs Poisonous to Cats and Dogs?

Yes, hyacinth bulbs are poisonous to pets. Many spring flowers, such as hyacinths and daffodils, contain a compound that may cause stomach and respiratory issues and skin irritation. This substance鈥攃alcium oxalate鈥攊s most concentrated in the bulbs, but is also found in the foliage and flowers of the hyacinth plant. Keep hyacinths out of reach of curious pets and children, and wear gloves when handling hyacinth bulbs for long periods of time.

The one upside to the hyacinth’s toxicity is that common garden pests, such as squirrels and groundhogs, often aren’t as tempted to eat your hyacinth bulbs!

Will Hyacinths Bloom Again?

Yes and no. Hyacinths bloom just once yearly (in the spring), but they will happily bloom again in subsequent years if provided with the proper care. They are a perennial plant.

Pests/Diseases

  •  Bulbs are prone to gray mold and bulb rot when kept too wet.

You should put bubls in the refrigerator for 2 to 3 months. Normally, you plant hyacinth bulbs in the fall because they are spring-blooming flowers. Bulbs should go in the ground before the first hard frost, ideally 6 weeks prior when soils are below 60 degrees F.

We live in southeast Michigan. Our H. are potted. I have cut all the bloom stems. The soil is drying out in one pot. The other is so new that it has not been watered. The dry-pot specimen nearly wilted completely this morning. The other, about 60% of the size of the first, still stands erect although the tips are folding over. What is the watering rule here?

Hi Stan,

Keep the soil moist so that the plants don’t wilt. The foliage will gradually turn yellow.

I planted Hyacinth bulbs for the first time and it seem that something is nibbling the tops off as they come up? I did not read anywhere that this could be a problem. Is this rabbits? What to do?

It’s not common that tops of hyacinths get chewed on. Usually it’s the bulbs that get eaten by moles and rodents. Hyacinths are not a favorite food for rabbits but if there is nothing else around they may nibble on them. Deer can also be a problem. If it happens again the best thing to do is to put up a fence around the plants.

hi, i force these to bloom. I think they were hyacinth bulbs but they look terrible, i tried putting this ribbon around them to make a prettier display but they are too floppy. the soil is moist. well lit room. Sort of yellow too. it can鈥檛 just be an issue with propping them up they aren鈥檛 healthy. The pot doesn鈥檛 have a hole in it so maybe they could be too wet? Lord help me if I have to drill a hole in the metal pots. woe is me. Cheers!
Kate

Hi Kate,

Move the hyacinths to a container with drainage holes. Let the soil dry out and only water when the soil is dry. Place the container in a sunny spot. If hyacinth blooms are large the stems bend. You can put a few stakes in the container for support.

I bought two plants that were already booming. I know when the leaves turn brown to trim them back, but how far? I live in Kansas and it is still cold at night so I don't want to move the pots outside yet, they are currently in a window with lots of sunlight. When I bought them they were soaked with water, enough that there was water standing on the surface of the soil. I did transplant them when I got them home(oops!) But they seemed to be doing fine. The flowers are dying off and the leaves are just now turning yellow, so from reading the article and quite a bit of the comments and questions I know soon I'll have to trim back the leaves. I've never tried my hand at flowers so I'm not sure how much to cut back or if I just cut in a straight line or really anything about this. Any help would be great. I love these flowers, so pretty and smell amazing! Thank you in advance for any advice or help you can give!

Let  the leaves turn brown naturally and you will easily pull them off the plant when dead.

I live in zone 7 and purchased two pots with 3 already bloomed flowers ( which were Not bloomed fully at the time I bought them) 2.5 weeks ago. I keep them in a window seal facing north until the weather permits me to go out and loosen soil in my garden beds. I love these beautiful hyacianths' and their fragrance is a delight. I have other lillies in the garden surrounding the house and have transported them and shared many with neighbors and friends as they took over one area bed.
My questions:
1. Will the hyacianths spread?
2. Can I just transplant them already bloomed right into the garden?
3. How deep do I plant them (bloomed) with foliage intacted?
Finally, can I seperate them?
Thank you if you can help me. These flowers remind me of my late parents... They did a lot of gardening and it is symbolic for me in their memory. I'm so ready to transplant!!
