How to cut rosemary 1, hydroponic cutting
Hydroponic cutting of rosemary should be carried out in spring and summer every year. Cut off healthy new branches of 65,438+00 cm, cut off the extra branchlets on the surface, then insert the branches into a transparent container filled with water, change the water every 2-3 days, and plant rosemary in fertile potted soil after taking root.
2. Soil culture cutting
When cutting rosemary in soil culture, we should choose the robust branches of the year, cut off the branches and leaves near the base, then bury the rosemary branches in soft and moist pot soil, and keep the spacing between the plants at about 4 cm, then move the pot soil into an environment with sufficient astigmatism, and wait for 1 month before rosemary takes root and survives.
3, vermiculite cutting
When cutting rosemary with vermiculite, vermiculite and perlite should be mixed in the ratio of 3:2 to make cutting matrix, and then the treated rosemary branches should be inserted into the matrix. Because vermiculite and perlite have no nutrition, rosemary should be sprayed with the mixture of rooting powder and carbendazim regularly after cutting to promote root growth.
4. Preventive measures
When rosemary was just cut, it didn't adapt to the environment and couldn't accept direct sunlight. At this time, it should be placed in a semi-cool or cool and ventilated place, and then moved into the sunny environment after the plants take root and germinate smoothly. Moreover, rosemary after vermiculite cutting is easy to grow poorly, so it should be transplanted into pot soil after rooting.
