Rosemary can be used as a potted plant and is also a good seasoning for cooking. So, how to propagate rosemary through cuttings? This article summarizes the best rosemary propagation methods based on a flower enthusiast's experience, including both water and soil propagation techniques.
Rosemary cuttings can not only be propagated in soil but also rooted in water before being transplanted into soil. Because different enthusiasts have their preferred propagation methods, we will describe both techniques.
I. Rosemary propagation by water rooting:
1. Use clean scissors to cut new thin branches from healthy and vigorous rosemary plants, avoiding branches with flowers. The cut should be close to the point where the leaves meet the branch (where there are more growth cells), and the cut surface should be clean and neat. The lower part of the rosemary branch is brown and hard, the middle part is grayish-white with light brown spots and is softer, and the newest part is green and flexible without breaking. Refer to the table below for the length of the cuttings:
2. Remove half of the leaves from the lower part of the cutting, place the prepared cutting in a transparent container, fill water to just below the leaves, and then place it on a sunny windowsill. Change the water every 2 to 3 days for the first week, and then change it when the water becomes cloudy or has visible sediment. After 5 to 8 weeks, white fine roots will grow from the lower half of the cutting. Continue soaking until the roots reach at least 5 centimeters long and there are 7 to 8 roots before transplanting. However, the more roots there are, the higher the survival rate and the faster the growth after transplanting.
3. Transplant into individual pots and water thoroughly. At this point, the cutting has not received nutrients for a long time and has produced many roots, consuming a lot of energy. When watering, you can add a little nutrient solution.
II. Rosemary propagation by soil cutting: Remove the leaves from the bottom third of the branch, fill the flower pot with loose fine soil, and press the soil down with your hands, but not too tightly. Water thoroughly, and then insert the prepared cutting directly into the loose soil, spacing them at least 4 centimeters apart, and place them in a sunny location.
Water thoroughly the first time and then once a week, keeping the soil moist on regular days. If the climate is dry, insert a stick or chopstick taller than the rosemary cutting into the pot and cover it with a perforated plastic bag, making sure the bag does not touch the cutting.
