Generally, the water can be changed once every 3-5 days when the ginger flower is hydroponically cultivated, and once every 10 days when it is just hydroponically cultivated, so that the water quality can be kept clean. In hydroponics, it is necessary to remove the root system from the soil first, then clean the root system, trim and disinfect it, and put it in a hydroponics container and add water to 2/3 of the root system. During curing, the nutrient solution should be dripped once every 7 ~10 days, and sufficient astigmatism and a warm environment of 25℃ should be maintained, and the roots should be pruned to make them grow vigorously.

Water-culture ginger flowers for 3 ~ 5 days, and change the water once.

Ginger flower is a plant with beautiful flowers, which can be cultivated in soil and cultivated in hydroponics. How often should the water be changed? Generally speaking, it needs to be changed once every 3-5 days to keep the water clean, but don't change the water too often just after hydroponics, about once every 10 day.

If you want to hydroponically cultivate the ginger flower, you need to dig it out of the soil first. In order to avoid damage to the root system of the ginger flower, finally, let the root be separated with the soil mass. After that, the soil is cleared, the root system of the ginger flower is cleaned, and the residual roots on it are trimmed properly to avoid poor root growth during hydroponics.

Then put it into potassium permanganate solution for disinfection. Note that the solution needs to be diluted with water. Take it out after 30 minutes and put it in a cool place to let the wind dry its root wound. Prepare the hydroponic container, put the ginger flower into it, and pay attention to the fact that its roots should be fixed in the planting basket with vermiculite, then add water to 2/3 of the roots, stop the water, and then maintain it.

It should be noted that in hydroponic maintenance, in addition to changing water regularly, nutrient solution should be dripped once every 7 ~10 days to make it full of nutrients, and a bright growth environment should be provided for hydroponic ginger flowers to receive sufficient astigmatism and a warm environment of about 25℃, and its roots should be pruned in time to make it grow healthily.
