If you want it to take root faster in water culture, you can add diluted aspirin tablets to the water. Specifically, use a pill to break, add a kilogram of clean water to dilute, and then add a few drops to the bottle every two days, so as to promote growth. Or soak the tablets in water before they are put into the bottle. Specifically, use three tablets, add 0.5kg of water, soak them for half a day and put them in the bottle. This can also achieve the goal
If it happens to be in spring during hydroponics, you can cut some willow branches into chopsticks like lengths, and then soak them in water. The water soaked for a day is a very good rooting water, and then you can mix it with water to drop it into a vase, so that it can not only accelerate rooting but also make its leaves green all the year round.
In addition to the above two methods, you can also add vitamin B2 into the water, and put the tablet directly in the vase. Pay attention not to put too much, just one tablet can, and it can also speed up its rooting speed.
