Growing hyacinths in a jar - that's what my grandparents did. The pretty spring flowers look even more decorative in the hyacinth glass. It takes a little patience for the onions to blossom. But then the hyacinths enchant the house with their unique scent of spring.

Does the hyacinth have to be poured in the glass?
The lower part of the glass must always be filled with water. However, the water level may only be so high that the roots but not the bulb itself comes into contact with water.
Pour in fresh water as soon as necessary. The roots must not dry out.
Does the hyacinth need fertilizer?
You must not fertilize the flower in the glass. Only select the largest possible, firm bulbs for cultivation. The larger the onions are, the more nutrients they have stored.
How long does it take for the onion to sprout?
You have to reckon with ten to twelve weeks. The onion will only sprout if the glass is in a cool place with a temperature of ten degrees.
In addition, the place must be dark. If necessary, you can cover the hyacinth jar with a paper hat.
Can the hyacinth be transplanted?
Transplanting does not make sense. The hyacinth only flowers for one season in the glass anyway.
Is the hyacinth cut in the glass?
You can cut off faded inflorescences. The leaves stay on the plant.
Which pests and diseases can occur?
Watch out for aphids and scale insects. If the onion is in the water, there is a high risk of onion rot.
What happens to the hyacinth glass after flowering?
If you grow a hyacinth in a jar, it will be used up after one season. It is worth trying to continue caring for them outdoors.
- Take the onion out of the jar
- Let dry a bit
- Cut faded
- Trim roots if necessary
- Choose a sunny spot in the garden
- Planting flower bulbs
tips and tricks
If you want to grow hyacinths in a jar, you should buy special hyacinth jars. They consist of a bulbous base on which sits a glass bowl. Only with suitable glasses can you prevent the flower bulb from coming into contact with the water.
