Hyacinths, crocuses, tulips, and daffodils already provide a foretaste of the coming spring at the window in winter. With these tips, you will succeed in driving the flower bulbs in the glass. Hyacinths only take a few weeks from inconspicuous onions to beautiful blooms. We show you how it works!
Did you know that you can drive many flower bulbs that actually bloom in spring in a glass and thus make them bloom in winter? This turns the onions into great indoor plants that add a little color to the house, especially in the dark wintertime. The commercial gardener’s box of tricks makes it possible! Already in late autumn, they believe onion flowers in cold stores to have an early but short winter so that by December they believe that it is spring and that they are producing splendid blossoms. Whether hyacinths, tulips, or daffodils: If you put the prepared flower bulbs on glasses with water, they will take root in two to three weeks at temperatures of eight to twelve degrees Celsius. The first flowers will open after another five to six weeks.
Flower bulbs in a glass: this is how it works
- Place the flower bulbs on vases filled with water. There should be an inch of space between the onion and the water.
- Cover the shoot tips with darkening hats and place the jars in a cool place at temperatures around ten degrees Celsius.
- Check the water level regularly. As soon as flower buds appear, place the bulb flowers in the warm.
Bulbs in a jar: what do you need to power them?
It is particularly easy to drive flower bulbs on special onion flower glasses, which are available in various colors and sizes in stores. The special shape of the glasses gives the onions a hold and prevents rotting. You can also cover vases or normal glasses with a vegetable net and place the onions on top. A bowl filled with pebbles with a little water is sufficient for small iris and crocus bulbs.
Step 1: Prepare the flower bulbs in blowing vases
A bed of gravel is sufficient for the hyacinth bulbs to take root
Forced vases have a narrow neck and a small bowl at the top in which the flower bulb rests. This protects the onion from getting wet. First, fill the glass with enough water so that there is about one centimeter of air left up to the flower bulb. Then place the vessel in a bright, cool place with temperatures around ten degrees Celsius. Check the water level regularly. Simply place the flower bulb on the glass and do not wet it with water while driving. When buying, look for large bulbs, they guarantee a wonderful bloom.
Step 2: Darken the flower bulbs in the glass
The cones for driving can be made from old calendar sheets, for example
Put a darkening hat on each of the flower bulbs in the glasses with water. The cap remains on the onion until the growing tip of the shoot lifts it. You can easily make the blackout caps yourself in various sizes from cardboard. As soon as the first flower buds appear, place the glass with the flower bulb in the warm. Shortly afterward, the shoot shoots up and forms a beautiful flower.
If the bulb flowers have faded, do not throw them away: They can still be cultivated wonderfully on the balcony, terrace, or in the garden. Our tips: Plant them and overwinter the flower bulbs in a bright, cool place. As soon as the frost has passed, they are planted in the garden.
Planting tips for amaryllis bulbs
The large amaryllis bulbs must not be completely covered with soil
Fresh potting soil brings the amaryllis flower bulbs, also known as the knight’s star, to life. A little expanded clay or gravel makes the earth even looser. Make sure the bulbs are firm and not rotten or moldy. The bulbs should only be planted deep enough so that a third of the ground is still visible. Pour only over the soil, not over the onions – at first only a little, the longer the shoot becomes, the more. First of all, you don’t need to fertilize the amaryllis.
Bulb flowers as house plants
The large flowers of the knight’s star are a lot of fun in winter
Bulb flowers are also wonderfully suitable as indoor plants – for example for winter decorations. The flowers of the knight’s star appear naturally when you put the pots on the windowsill in a warm room. After flowering, the elongated leaves typical of the knight’s star develop. It is best to place the plants outside in the garden, on the balcony or terrace from mid-May.
