How to propagate roses in winter
Let's talk about how to propagate roses in winter and the methods and steps of rose propagation in the field of green plants and flowers. Let's take a look together!
Roses have beautiful flowers and a long blooming period, so many flower enthusiasts like to grow pots of roses at home for appreciation. They also propagate the branches cut off during pruning. Now it's getting cold in winter, and many flower enthusiasts want to try propagating roses in winter, but they don't know if they can survive.
In fact, roses can be propagated in all seasons. The reason why roses are not propagated in winter is because the environmental temperature is too low, and it is not easy for the cuttings to root after propagation. However, as long as the indoor temperature is above 18°C, roses will root quickly after propagation. One benefit of propagating roses in winter is that it is less likely to have black stems, as the low temperature in winter reduces the chance of bacterial infection at the wound. With a suitable temperature, the cuttings are more likely to root and survive.
Prepare propagation vessels
Since the outdoor temperature is too low in winter, it is no longer suitable for direct outdoor propagation. It's best to find some small plastic cups or cut the top half off plastic mineral water bottles and puncture a few small holes in the bottom for drainage. You can also use flowerpots and fill them with loose and breathable growing soil to propagate roses, as long as it can be placed in a warm indoor environment for care.
Preparing the propagation medium
Everyone has encountered the phenomenon of black stems in rose cuttings during propagation. This is often due to the soil being too sticky, with poor water permeability and aeration, leading to black rot at the base of the cuttings. To improve the survival rate of propagation, the choice of medium is very important. When preparing the propagation medium, you can mix and use vermiculite, perlite, fine coconut bran, etc., or use clean river sand directly, which can also have a very good rooting effect.
Pruning branches
When pruning roses in winter, you can directly use the cut branches for propagation. Select a few healthy branches, cut them into 10-15 cm cuttings, each with more than three buds. Cut the bottom of the cuttings at a 45-degree angle to increase the absorption area. In winter, there's no need to retain the leaves at the top of the branches without foliage.

Processing cuttings
If you're not confident in your propagation skills, you can sterilize and disinfect the cuttings before planting. Soak the cuttings in a 0.2% potassium permanganate or carbendazim solution to kill bacteria, then dip them in a rooting hormone before planting. This can effectively improve the rooting and survival rate of the cuttings.
Propagation operation method
Fill the prepared medium into the growing vessels, spray it slightly damp, 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 the propagation can survive in winter depends on whether there is a suitable environmental 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, which can both insulate and moisturize, allowing the cuttings to root more quickly.
Even after the roses have survived in winter, don't rush to transplant them into pots. The survival rate of transplanting at this time is very low. It's best to wait until spring warms up and the cuttings have grown a lot of new buds before transplanting them into new pots, which will be easier to survive.
