In the process, you have to “trick” the bulbs into pretending they survived the winter so they can flower. This means that they must experience a constant cold environment while in a dormant state.
As a general rule, short-stemmed tulips tend to respond better to the growing process than long-stemmed varieties.
The most important thing is to choose healthy, large and firm bulbs.
Place a few balls in a clean vase up to 1/3 of the way up the jar. Their purpose is to let you use less water in the process and to let the tulips’ roots rest on them.
Place the tulip bulb upside down inside the vase until it sticks inside.
Pour clean water up to 1 cm below the bulb. It is very important that the bulb does not touch the water.
Leave the vase in a cool, dark environment to allow it to grow. You have to wait about 16 weeks. You must change the water regularly. Always keep the water at the same level.
When the 16 weeks are over, you can place the vase in sunlight. Don’t forget to change the water regularly.
The right climate is very important to ensure the growth of tulips inside the water. For this you may need cooling and also sunlight right after 16 weeks. If you live in areas with long winters, this may not work.
Cool for the time recommended for the species. They can get cold in the coldest, darkest place in your house; basement, garage or fridge, just be careful not to put them next to apples. The gas given off by fruits such as apples will prevent them from blooming.
For growing a hyacinth bulb, this method is an especially easy way to bring some spring into your home before they start blooming naturally. You can use pots specially made for this purpose, or any vase or vase with a mouth small enough to hold the bulb without it falling into the water.
The purpose of a reinforced glass is to keep the bottom of the bulb away from the water. A bulb that sits directly in water will rot, but if the basal plate (the bottom of the bulb where the roots grow) is just out of reach of the water, it will begin to root and eventually flower.
Hyacinth bulbs must be chilled before they bloom. You should place the bulbs in a labeled paper bag, make sure the bag is protected from moisture and leave cool for 8 weeks. This can be the refrigerator or any other cool, dark place where the temperature does not exceed 50ºC.
Place the vase in the light, but not in direct sunlight for the first 10 days when the bulb turns green and grows rapidly. Filtered light in a room is perfect.
