How to fertilize hydroponic hyacinths
Here are some tips on how to fertilize hydroponic hyacinths and related knowledge about the hydroponic method and precautions for hyacinths. The following is an introduction for you.
1. Selection and planting points of hydroponic hyacinth bulbs
When selecting hyacinth bulbs, pay attention to the following points:
1. Try to choose bulbs with a larger diameter, as larger bulbs generally have better flowering ability.
2. The top bud of the bulb should be full and intact without withering or yellowing.
3. The outer skin should be intact, and the inside should be clean and smooth after peeling.
After selecting the hydroponic hyacinth, try to complete the planting according to these steps:
1. Peel off one or two layers of the outer skin of the bulb and trim the withered and poor roots at the bottom of the bulb.
2. Soak the bulb in a carbendazim solution for about half an hour to greatly prevent the occurrence of diseases and pests.
3. Place the bulb in a special hydroponic hyacinth bottle, or you can use other wide-mouthed, thin-necked glass containers, add water, and let the bottom of the bulb just touch the water.
2. Care before sprouting of hydroponic hyacinths
Before sprouting hydroponic hyacinths, the following points must be taken care of, otherwise they will not only affect germination but also affect future flowering:
1. Before germination, place the hydroponic hyacinth in a cool, dark place. The most suitable temperature for the rooting of hydroponic hyacinths is 2 to 6 degrees. If the temperature is too high, it cannot break the dormancy of the hyacinth, affecting its rooting. If you do not have low-temperature conditions, you can place the hyacinth bulb in the refrigerator's fresh-keeping compartment and adjust the temperature, then take it out for hydroponics after rooting.
2. If adding a special nutrient solution, only add a little to the bottom of the bottle, not too much.
3. To speed up the rooting process, you can wrap the bottle of the hydroponic hyacinth with a black plastic bag or black cloth to create a darker environment more conducive to rooting. After the white roots grow well, you can remove the wrapping material for normal care.
3. Care after the roots and sprouts of hydroponic hyacinths have grown
After the roots and sprouts of hydroponic hyacinths have grown, the following points should be noted for care:
1. Temperature: From germination to bud formation, it is best to place the hyacinth in a temperature range of 5 to 10 degrees to allow it to go through a vernalization process, which is more conducive to the germination of flower buds. High temperatures will affect bud formation and flowering.
2. Light: During the stage from germination to bud formation, hyacinths can be given sufficient light, which is more conducive to the germination of flower buds.
3. Water change: After hydroponic hyacinths germinate, it is generally recommended to change the water every 7 days. If using tap water, it is best not to use it directly. It should be exposed to sunlight for a day or settled for 24 hours before use.

4. Care during the budding stage of hydroponic hyacinths
Once the hyacinth has developed flower buds, the care routine needs to change and should be different from before budding:
1. Temperature: When there are signs of flower bud differentiation in the hydroponic hyacinth, it should be placed in a temperature range of 15 to 18 degrees for care. This temperature will help the hyacinth to better develop flower buds.
2. Light: Continue to provide sufficient light, as adequate light can help the hyacinth develop more and larger flower buds.
3. Fertilization: During the budding stage, you can apply a phosphorus-potassium-based special hydroponic plant fertilizer to promote flowering.
5. Care during the flowering stage of hydroponic hyacinths
Care for hydroponic hyacinths during the flowering stage should include the following points:
1. Temperature: During the flowering stage, try to place the hydroponic hyacinth in a temperature range of 10 to 15 degrees to extend the flowering period.
2. Light: During the flowering stage, avoid direct sunlight or too strong light. Placing it in a place with sufficient scattered light is more conducive to extending the flowering period of hydroponic hyacinths.
3. Add a piece of aspirin to extend the flowering period: Aspirin can extend the flowering period of plants. You can try adding a piece to the water during the flowering stage of hydroponic hyacinths.
4. Fertilization: Stop using any fertilizer. Hyacinths do not require much fertilizer, and as long as there is enough nutrition in the early stage, they can bloom well. Therefore, no fertilizer is needed during the flowering stage of hyacinths, as excessive fertilization can easily cause a short flowering period.
6. Disease and pest control of hydroponic hyacinths
Hydroponic hyacinths do not have many diseases and pests. The most common diseases are yellow rot and sclerotinia disease, which need to be controlled as follows:
1. Control of yellow rot: Regularly change the water to keep it clean, which is the key to preventing yellow rot. If you see yellowish-brown water stains or spots on the leaves of the hyacinth and yellowish liquid inside the bulb, it is yellow rot. In this case, you can spray the hyacinth with a 50% carbendazim solution diluted 1000 times for treatment. Both the leaves and bulbs should be sprayed. Clean the bulb before spraying and disinfect the hydroponic bottle after spraying before replanting.
2. Sclerotinia disease: Sclerotinia disease usually invades from the bulb, leading to yellow circular or streaked spots on the leaves. In the early stages of the disease, you can spray the bulb with Bordeaux solution. If it is severe, it is difficult to treat and should be discarded.
Hyacinths symbolize romantic love, with rich colors and a strong fragrance. Hydroponic hyacinths are also very clean and hygienic, making them popular among flower enthusiasts. They are one of the important bulbous ornamental flowers in winter and spring. To grow hydroponic hyacinths well, it is best to follow their growth characteristics at different stages and pay attention to keeping the water clean. Their beautiful flowers and rich fragrance will make people feel relaxed and happy.
The above introduction on how to fertilize hydroponic hyacinths and the hydroponic method and precautions for hyacinths can be used as a reference for everyone.
