Growing bulbs in a vase, also known as forcing bulbs, is a simple way to enjoy indoor blooms during the winter months. Here's how to do it:
Step-by-Step Guide to Forcing Bulbs in a Vase
-
Choose the Right Bulbs: Select bulbs specifically suited for forcing, such as hyacinths, paperwhite narcissus, amaryllis, or tulips. These varieties are known to thrive indoors.
-
Select Your Vase: Use a glass vase specifically designed for bulb forcing, or any vase with a narrow neck that will support the bulb above the water. Alternatively, you can use pebbles or marbles to support the bulb.
-
Add Water: Fill the vase with water, ensuring the water level is close to the bottom of the bulb, but not touching it. The roots will grow down into the water. If using pebbles or marbles, fill the vase to just below where the base of the bulb will sit when placed on the pebbles/marbles.
-
Chill the Bulbs (Important for most Bulbs): Place the vase with the bulb in a cool, dark place, such as a refrigerator (not freezer!) or unheated garage, for 8-12 weeks. This chilling period is crucial for root development and flower formation, especially for hyacinths and tulips. Paperwhites and amaryllis might not require chilling. Check the specific instructions for the type of bulb you're using.
-
Monitor Root Growth: After about 2-3 weeks, you should start seeing roots growing into the water. Replenish the water as needed to maintain the level, ensuring the bulb base remains above the water.
-
Move to a Warmer, Brighter Location: Once the roots are well-developed (several inches long) and a sprout appears, move the vase to a warmer room with indirect sunlight.
-
Turn Regularly: Rotate the vase regularly to ensure even growth and prevent the stem from leaning towards the light.
-
Enjoy the Blooms: Within a few weeks, the bulb will bloom, providing beautiful flowers and fragrance indoors.
Tips for Success
- Clean Water: Use fresh, clean water and change it regularly (every week or two) to prevent bacteria growth.
- Support Tall Stems: If the flower stems become too tall and floppy, use a stake or support to keep them upright.
- Discard After Flowering: Once the bulb has finished flowering, it can be discarded as it is unlikely to re-bloom well when forced. However, some sources say you can plant them outside in the fall, but do not expect blooms the following year.
