Rose cuttings turned black after a month - let me teach you a trick to root roses in any season

A gardening friend took rose cuttings, and after a month they had not rooted. When pulled out to check, callus tissue had formed, but no roots had grown, and then the stems turned black. What is going on? Let us take a look today

This rose cutting has already turned black, which means the propagation has failed. The callus tissue growing at the bottom shows that it was only a few days away from success. So what caused this?

It is very likely caused by poor air permeability of the cutting medium, or by the environment being too dry. I do not know what medium was used for the cuttings. For rooting cuttings, it is best to use plain soil; you can use river sand, vermiculite, perlite, etc. for cuttings. They have good air permeability and decent water retention. After inserting the cuttings, you can cover them with a bag to retain moisture, poke a few holes in the bag for ventilation, and reduce transpiration from the leaves,

Create a warm and humid environment for it. The cut wound on the stem can be sprayed with carbendazim solution to disinfect it and reduce the occurrence of black stems

The cutting method I often use is the vermiculite cutting method. This method is simple and easy to do, and even beginners can root cuttings successfully. It is especially simple,

Take a mineral water bottle, fill it with vermiculite, drill a few holes in the bottom, insert the cutting into it, then water thoroughly. Place a saucer under the bottle and keep about 1 cm of water in it. Just put it directly in a place with plenty of diffused light to get sun, and make sure ventilation is good. Keep an eye on the water in the saucer and do not let it run out, because the bottom stays moist and airy,

So rooting is very fast, and roots can form in about 20 days or so. Moreover, whether it is bud cuttings or stem cuttings, they all root very easily. If your rose cuttings never survive, you might as well try this method. The survival rate is very high
