How to care for roses in water
Cultivating roses in water not only fills the living space with a romantic atmosphere but is also cleaner and more convenient than soil cultivation. However, many rose enthusiasts find that water-cultivated roses tend to wilt and rot easily, often due to neglect in container selection, water treatment, and care techniques. Master the following six key points to make your roses bloom for more than 15 days in a hydroponic environment.
One, scientific selection of hydroponic containers
Transparent material to observe the root system
It is recommended to choose a narrow-necked bottle made of high-boron silicon glass, as the transparent material allows for easy observation of the water level and root condition. The height of the bottle should be 2/3 of the length of the flower stem, with a diameter of 8-10cm being the most conducive to air circulation.
Bottle mouth design to prevent toppling
Preferably choose a bottle with a narrow opening to physically support the flower stem and prevent it from falling over. Placing 3-5 pebbles at the bottom of the bottle can stabilize the plant and also form a micro-ecological filtration layer.
Two, key steps in water treatment
Double water purification method
Boil tap water and let it cool, then let it sit for 24 hours. Add 2 drops of citric acid (per 500ml of water) to adjust the pH to 5.5-6.0. Alternatively, use the water from an RO reverse osmosis water purifier, ensuring the TDS value is less than 50ppm.
Scientific nutrient solution ratio
Add 0.5g of hydroponic nutrient solution for flowers to each liter of water, with a nitrogen-phosphorus-potassium ratio of 1:2:2. You can also add 1/4 of an aspirin tablet to inhibit bacterial growth.
Three, pre-treatment of flower stems
45-degree oblique cutting technique
Use a branch剪 that has been disinfected with alcohol, and cut the flower stem under running water. The cutting angle should be strictly controlled between 45-60 degrees, with each 1cm cut increasing the water absorption area by 30%.
High-temperature sealing treatment
Soak the cut end in 80℃ hot water for 30 seconds to quickly form a protective film. This operation can reduce juice loss by 70% and extend the freshness period by 3-5 days.
Four, intelligent care system
Three-time light avoidance method
Place in a diffused light environment from 10:00-16:00 daily, and cover with shade for the rest of the time. Combine with daily misting to maintain an environmental humidity of 65%-75%.
Water change cycle formula
Change water every 5 days when the water temperature is below 20℃, every 3 days when it is between 20-25℃, and daily when it is above 25℃. Each time you change the water, retain 1/3 of the original solution to maintain bacterial balance.
By following a systematic care plan, combined with techniques such as adding a vitamin C tablet (1/4 tablet each time) and cold storage preservation (16℃ at night), the viewing period of hydroponic roses can be extended to 18-22 days. Regularly check the stem for stickiness, and promptly cut off any diseased parts to make this romantic touch in the water last longer.
