How to propagate roses in winter
Let me share with you some experiences on plant care regarding how to propagate roses in winter and the simplest method of rose propagation. Let's take a look together.
Roses bloom beautifully with a long flowering period, and many rose enthusiasts like to grow them at home for admiration. Every time they prune, they also propagate the branches through cutting. Now it is the cold winter, and many enthusiasts want to try propagating roses in winter, but they are not sure if they can survive.
In fact, roses can be propagated throughout the year. The reason why propagation is not done in winter is because the ambient temperature is too low, and it is difficult for the cuttings to root after propagation. However, as long as the indoor temperature is above 18°C, the roses will root and survive quickly after propagation. One advantage of propagating roses in winter is that it is less likely to develop black stems because the low temperature reduces the chance of bacterial infection at the wound. With suitable temperature, the cuttings are more likely to root and survive.
Prepare propagation vessels
Due to the low outdoor temperature in winter, it is no longer suitable to propagate directly outside. It is best to find some small plastic cups or use half-cut plastic bottles, puncturing small holes in the bottle bottom for drainage. You can also use a flower pot filled with loose and breathable culture soil to propagate roses, as long as it can be placed in a warm indoor environment for care.
Preparation of propagation medium
Everyone has encountered the phenomenon of black stems when propagating roses. This is mostly due to the soil being too sticky, with poor water and air permeability, leading to black rot at the base of the cuttings. Therefore, to improve the survival rate of propagation, the choice of medium is crucial. When preparing the propagation medium, you can mix and use vermiculite, perlite, fine coconut bran, etc., or directly use clean river sand, which can also achieve very good rooting results.

Prune branches
When pruning roses in winter, you can directly use the pruned branches for propagation. Select a few healthy branches, cut them into 10-15 cm cuttings, ensuring each section has at least three buds. Cut the bottom of the cuttings at a 45-degree angle to increase their absorption area. In winter, there is no need to retain the top leaves without foliage.
Handling cuttings
If you are not confident in your propagation skills, you can also sterilize and disinfect the pruned cuttings before propagation. Soak the cuttings in 0.2% potassium permanganate or carbendazim for sterilization, then dip them in a rooting hormone before propagation. This can effectively improve the survival rate of the cuttings.
Propagation method
Fill the prepared medium into the culture vessels, spray it slightly moist, then insert the bottom of the processed cuttings into the medium, with a depth of about 3 cm. After planting, you can cover the mouth of the bottle or the entire pot with plastic, puncture a few small holes for ventilation, and place it in an environment with weak scattered light for care.
Avoid low environmental temperatures
Whether propagation can survive in winter depends on whether there is a suitable ambient temperature. If the indoor temperature is below 15°C, the cuttings will not grow and will not root easily. You can cover the pot with a plastic bag to keep it warm and humid, which will help the cuttings root faster.
Even after the roses have survived in winter, do not rush to transplant them into a pot. The survival rate of transplanting at this time is very low. It is best to wait until spring when it is warm, and the cuttings have grown a large number of new buds before transplanting them into a new pot, which will be easier to survive.
The above is a detailed introduction on how to propagate roses in winter and the simplest method of rose propagation. Have you understood it?
