Rose cuttings turned black-stemmed? Let me teach you a trick to root them successfully in any season

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

This rose cutting has already turned black-stemmed, which means the cutting 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 the cutting soil, 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 keep in moisture, poke a few holes in the bag for ventilation, and reduce the transpiration of the leaves.

Create a warm and humid environment for it. The wound on the cutting 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. Even beginners can get cuttings to root. 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 bright indirect light to sun it. Ventilation should be 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. It can root 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.
