1, temperature control
It may be that the temperature of water-inserted roses is not suitable, and the suitable temperature for flowering is between 18-25 degrees. Above 30 degrees or below 15 degrees, it is easy not to bloom, and it will also lead to rotten flowers. Only by keeping it at a suitable temperature can it bloom normally.
2. Change the water regularly
Roses in water have high requirements on water quality, so it is necessary to change the water regularly to ensure the water quality is clean. Change the water every 5-7 days in summer, every 15 days in spring and autumn, and observe the water quality every 20 days in winter. Change the water immediately if it is slightly turbid.
3. Strengthen ventilation
Water-inserted roses are difficult to blossom if they are not ventilated indoors for a long time. Open the window for 2-4 hours every morning and evening to let the indoor air circulate. At the same time, astigmatism irradiation is needed for photosynthesis to accelerate flowering.
Rose hydroponics
1, pruning
If you want to raise the bought roses in water, you should prepare a pair of sterilized sharp scissors, cut the bottom of the flower branch into a smooth 45-degree oblique mouth to increase the absorption area of the rose, and then cut off the leaves of the rose branch to avoid losing excess nutrition and prolong its survival time.
2. Hydroponics
When hydroponics roses, you need to prepare a clean and pollution-free vase, and then fill it with half of the water. Tap water can be left standing for two days before use, and then roses are inserted in vases, and rooting water or nutrient solution is dripped into the vases.
3. Suitable environment
Hydroponic roses need little light. When planting roses, it is necessary to place the plants in a ventilated and semi-shady place to avoid direct sunlight and maintain the normal growth of roses. However, in winter, roses can be placed in sunny places and receive all-weather natural light.
