Growing hyacinths in a glass – that’s what my grandparents did. The pretty spring bloomers look even more decorative in the hyacinth glass. It takes a little patience for the bulbs to sprout flowers. But then the hyacinths enchant the house with their unique scent of spring.
What is the best way to grow a hyacinth in a glass?
How do you care for a hyacinth in a glass? Make sure that the bottom part of the glass is always filled with water, but that the onion is not in the water. Fertilizing is not necessary, but fresh water must be added regularly. After flowering, the bulb can be cultivated outdoors.
Does the hyacinth in the glass have to be watered?
The lower part of the glass must always be filled with water. The water level should only be high enough so that the roots but not the bulb itself come into contact with water.
Pour fresh water as soon as necessary. The roots must not dry out.
Does the hyacinth need fertilizer?
You are not allowed to fertilize the flower in the glass. Choose only the largest, firm onions possible for cultivation. The larger the bulbs are, the more nutrients they have stored.
How long does it take for the onion to sprout?
You should expect ten to twelve weeks. The onion only sprouts if the jar is in a cool place that is ten degrees warm.
The place also has to be dark. If necessary, you can cover the hyacinth jar with a paper hat.
Can the hyacinth be transplanted?
Transplanting doesn't make sense. The hyacinth only blooms in a glass for one season anyway.
Is the hyacinth cut in the glass?
You can cut off spent inflorescences. The leaves remain on the plant.
What pests and diseases can occur?
Watch out for aphids and scale insects. If the onion is in water, there is a high risk of onion rot.
What happens to the hyacinth glass after flowering?
If you grow a hyacinth in a glass, it will be used up after one season. It's worth a try to continue cultivating them outdoors.
- Take the onion out of the jar
- Let it dry a bit
- Cutting faded flowers
- Short the roots a little if necessary
- Choose a sunny location in the garden
- Planting flower bulbs
