The stem segments of rosemary can generally take root quickly and establish new plants under the conditions of light and humidity. The following are some suggestions to improve the cutting success rate of rosemary:
1. Select a healthy stem segment: ensure that the stem segment is complete, free from pests and diseases, and has 2-3 top leaves. Stem segments should be upright and strong.
2. Incision treatment: Use sharp tools, such as scissors or blades, to trim the bottom of the stem segment at a 45-degree angle and ensure that the incision is clean. This is helpful to improve the water absorption of stem segments and form new roots quickly.
3. Hydroponics environment: Choose containers suitable for hydroponics, such as transparent bottles or vases, and add purified water. Ensure that the lower end of the stem segment can be completely immersed in water, but the top leaves should be kept dry to prevent the leaves from getting wet.
4. Plenty of light: Rosemary likes sunshine, so put the container in a well-lit place, such as near a window. If the sunshine is insufficient, consider using artificial light sources to provide extra light.
5. Suitable temperature and humidity: The suitable temperature range of rosemary is 20-30 degrees Celsius. It is also important to maintain proper humidity conditions and avoid excessively humid or dry environments.
6. Change the water regularly: change the water once a week to keep the water clean. If necessary, an appropriate amount of hydroponic nutrient solution can be added to provide nutrients.
7. Patience observation: It often takes some time for the stem segments to take root, so be patient. Observe whether there are new roots at the bottom of the stem segment. If there is rot or other abnormal situation, take timely measures to adjust.
Generally speaking, rosemary cuttings can usually take root and survive successfully as long as proper environmental conditions and correct operation methods are paid attention to.
