Solutions for Rose Cuttings That Won't Root

The rose is known as the queen of flowers. Rose propagation methods include grafting, sowing, cuttings, layering and so on. Because of its high survival rate, cuttings have become a common method for flower growers. But recently some flower lovers have reported that their rose cuttings won't root. What is going on here?

Failure to root for a long time is mostly caused by diseased or weak cuttings. For cuttings, you can choose semi-lignified branches from after flowering, which are rich in nutrients and help rooting. The branch should carry 1~2 growth buds and leaves, which helps the branch sprout.

The wounded part of the cutting is prone to viral infection, so before potting it can be disinfected and sterilized with a carbendazim solution. For rose cuttings rooted in water, because the roots dislike a bright environment, you need to provide some shade appropriately or use vermiculite for rooting.

In addition, rose cuttings rooted in water need to have their water changed frequently; poor water quality or improper water changes can also easily make the cuttings rot and turn black. Also, at a temperature of 22-25°C, rose cuttings root most easily, so you should control the temperature well and do a good job of keeping them warm and moist.
