1、 Prune branches

Before cultivating Platycodon grandiflorum in water, its branches need to be simply trimmed. First of all, the rotten pedicels should be trimmed off, and the leaves at the bottom should also be cut off. A section of the bottom should be cut off obliquely at an angle of 45 °. In this way, the branches will better absorb water after being inserted into the water, and they should be trimmed every two days

2、 Water level

The height of the water level is also very important. Many flower friends will ignore it. The height of the water level should exceed 1 / 3 of the vase. If possible, add some preservatives to make it bloom longer

3、 Water change time

If no preservative is added, change the water for it once a day. The water with preservative can be changed once every 3-4 days. When changing water, you should also clean the vase or disinfect it with disinfectant, which can kill some bacteria

4、 Placement position

Don't always be exposed to sunlight during maintenance, which will accelerate the evaporation of water in Platycodon grandiflorum and shorten its survival time. The place should be far away from the air outlet, especially the air outlet of the air conditioner. The ventilation does not need to be too good
