A dracaena grown in water needs regular checks of the roots and water. Use products intended for that growing method rather than a homemade nutrient recipe.
Nutrient solution
Use a nutrient product intended for the identified plant and water-growing method. Follow its label rather than mixing an improvised acidic solution.

Light
The seedlings that are just planted are placed in a darkest place for slow seedlings. After that, when the seedlings grow normally, they can move to a place with sufficient light. In addition, Brazilian wood likes the sun. Except for summer, it can maintain sufficient light in other seasons. In summer, it is necessary to prepare for shading to prevent the Brazilian wood from being directly exposed to sunlight. In winter, we must pay more attention to the sufficient light. In addition, Brazilian wood likes warmth. In winter, it should ensure that room temperature is more than 10 degrees Celsius, so that Brazilian wood can grow better and safe through winter.

Watering
When Brazilian wood is too dry in the indoor air, the phenomenon of rolls of the leaves will appear. When this phenomenon appears, you can choose to spray water around or put a water basin to increase air humidity. In addition, when the plant is too high, the trunk part of the top should be trimmed in time, so as to germinate new branches, it is also more suitable for the appearance of Brazilian wood, which is convenient for people to appreciate and watch.
