In spring or early summer, cut 5-10cm green and tender new branches. From summer to early autumn, 10-15cm gray and white branches should be cut. In autumn, 15-35cm Brown hard mature branches should be cut. First, cut the new twigs from rosemary with clean scissors, and pay attention to avoid the twigs with flowers. The cut should be under the place where the branches and leaves connect. The cut should be clean and tidy. Remove about 1 /2 of the leaves under the lower half of the branch, put them into a transparent container, and inject water to the height below the leaves. Put it on the sunny windowsill. Change the water every two to three days in the first week, and then change it when the water becomes turbid or there is obvious sediment. Five to eight weeks later, the second half of the branch will have white roots, and continue to soak. When the roots are 5cm long, they can be transplanted. Transplant into a separate flowerpot and water it. When watering, you can make up a little nutrition properly.
Remove 1 /3 of the leaves under the branch diameter, fill the soft fine soil into the flower pot, press the potted soil flat, and water it. Insert the treated cuttings into the fine soil. If there are more branches, the spacing shall be at least 4cm. Put the flowerpot in a sunny place and keep the soil moist on weekdays. If it is similar to the dry climate in the north, you must put a stick or chopsticks higher than the cuttings in the flowerpot, and then cover the plastic bag with holes, and do not touch the cuttings.
Use the ratio of 2:3 to make the cutting matrix of vermiculite and perlite, and put it in the lattice of the hole plate. With a pot of rooting powder + carbendazim solution, spray it in case of water shortage. Next, ensure that Rosemary's drainage and disinfection are normal until the root is produced.
