To propagate a rose, you will need just one unopened bud of this flower. And you will also need a head of red onion.
The bud must be cut with a sterile scalpel.
Then you need to cut off the top of the onion and make several cuts in it to release the juice.
The bud needs to be shortened a little and inserted into the bulb.
This structure should be placed in a pot with good drainage and loose soil.
Water the bud and cover it with a plastic cup. In just twenty days you will notice the growth of the root system, and the bud will open.
Then you need to transplant the flower into a more spacious pot and feed the flower with fish meal so that it develops well.
Further care should be the same as for other roses.
