How to Grow Hyacinths in Water and Detailed Steps
How to grow hyacinths in water. For water culture, hyacinths can be grown by selecting large, well-developed bulbs in September to October and placing them at the mouth of a glass bottle with a cup-shaped opening. Fill the bottle with water, with the water level just below the base of the bulb. Add a small piece of charcoal to absorb impurities in the water and prevent it from becoming foul. If the bottle opening is larger than the bulb, pack cotton tightly around the bulb to hold it in place. Then place the bottle with the bulb in a cool, dark spot indoors, keeping the room temperature at 10-15°C.
After about 1 month, roots will grow. Once the roots are fully developed, move the bottle to a spot without direct light and keep the temperature at 15-20°C. Add water frequently but do not let it reach the roots. There is no need to change the water or fertilize. After leaves appear, light can be increased appropriately. Once buds form, expose to sunlight for 1-2 hours a day to make the leaves and flower stalks grow strong. Rotate the light direction frequently so the plant does not grow leaning to one side. After the flower stalk bolts, change the water once every 3-4 days. After the flowers fade in March to April, take out the bulb and plant it in a pot. When the leaves wither, dig up the bulb and store it well, and it can be replanted in autumn.
Hyacinths can also be grown in water using the method for Chinese narcissus. In a shallow pot with an elegant shape, place a small amount of pebbles to hold the bulb in place, pour in clean water, cover the pot surface with black paper, and keep it in a dark room to encourage rooting. After the flower stalk begins to bolt, move it to a bright, warm spot by a window indoors to let it bloom. The above is an introduction to how to grow hyacinths in water.
How to Grow Hyacinths in Water

I. Steps Before Water Culture of Hyacinths
1. Add clean water to the glass bottle, but make sure the water level just does not touch the base of the bulb.
2. Use an ordinary glass cup or a specially made flower glass bottle to grow it. The bottle is divided into two parts, upper and lower, with the upper part smaller and the lower part larger;
3. For the glass cup, a wire can be used as a tray, hung down from the rim of the cup.
4. Fill the lower part with water and put a piece of charcoal in the water to prevent it from becoming foul.
5. Choose an especially large bulb, place it 5 cm from the mouth of the cup or bottle, immerse it in water, and place it in sunlight.
6. When the sprout grows to 5 cm, place it in a dark spot. After the roots are fully developed, place it in a warm spot without direct sunlight. Add water frequently so the water reaches the bulb. When leaves and flower buds grow, expose it to sunlight for 1-2 hours a day to make the leaves and flower stalks strong; rotate the direction every day so it does not grow leaning to one side.
7. No fertilization is needed, and in March to April of the following year it will produce a bright, fragrant hyacinth flower. After the flowers fade, take it out with the roots, plant it in potting soil, and when the leaves wither, dig it up and store it well; it can be planted again next year.
II. Care Methods
1. Place the hyacinth in a cool, dark, well-ventilated spot, keep the temperature at 9°C to 13°C, and check once a week to see whether water needs to be added.
2. When the flower bud grows 8 cm out of the bulb (after about 10 to 12 weeks) and the glass bottle is full of roots, the hyacinth can be moved to a warm room.
3. In an environment at home kept at 17°C to 20°C, you will enjoy the process of bud growth and color development. But do not place them directly near a heat source, so the beautiful hyacinth flowers can stay in bloom longer.
4. After flowering, the bulb can be planted in your yard. In summer you can use a glass bottle for flower arrangements, and in winter you can buy a treated hyacinth and reuse it.
How to Grow Hyacinths in Water, Methods for Growing Hyacinths in Water
Gardeners who have experience with growing hyacinths know that hyacinths can be grown not only in soil but also in water. Today I will briefly introduce the methods for growing hyacinths in water for everyone's reference and learning.
Methods for Growing Hyacinths in Water
1. After receiving the bulb, do not rush to open it, and be sure to pay attention to protective measures, because some gardeners may be allergic, so it is best to wear gloves, or wrap your hands with a plastic bag, then unpack it, and put the bulb into a prepared carbendazim solution to soak for 10-20 minutes for disinfection and sterilization. Take it out and let it dry in a cool place (do not rush to grow it in water before it dries, as it easily rots).
2. For the container used for water culture, any container is OK, but it is best to use a taller one, such as a waisted water culture bottle. Other water culture bottles are the same, and of course using your own drink bottle is OK too.
3. How much water to put in when growing hyacinths in water is a relatively important question, because later some gardeners found that hyacinths grown in water can develop mold and rot, which is related to too much water. The water level should just reach the root plate of the hyacinth; there is no need to submerge half the bulb.
4. It is understood that the rooting temperature for hyacinths is around 9°C, so during rooting, placing them in a completely dark environment is beneficial to root growth. At this time gardeners may think of putting the hyacinth in a dark room; the principle is the same. After putting it in a dark room, just place the hyacinth in a cool, ventilated spot for care.
5. When adding water during water culture of hyacinths, remember not to sprinkle it on the bulb, as this can easily cause mold. You can add water along the wall of the bottle. Again, do not let the water level be too high.
6. What should be done if mold is seen on a hyacinth grown in water? This situation is relatively normal, mainly because the air is too humid, so a dry environment is less prone to mold. If mold appears, gardeners can use a cotton swab dipped in carbendazim solution to clean the moldy spots; there is no major problem.
7. What should be done if the roots rot? A few gardeners may encounter this unusual outcome: the roots of a hyacinth grown in water rot. In this case, it is recommended that gardeners take out the bulb, clean off the rotten roots, then dry the hyacinth again and plant it in soil.
In addition, hyacinths grown in water should be given fresh water frequently, about once a week. When changing the water, just pull the hyacinth bulb partway out of the water culture bottle, avoiding breaking the roots.
Summary: The above is knowledge about growing hyacinths in water. I hope it is helpful to gardeners growing hyacinths.
