Can roses be rooted from cuttings in winter?
Today, I will explain in detail whether roses can be rooted from cuttings in winter, as well as share some small experiences about the care of green plants, such as the timing and methods of rose cutting propagation. Next, the editor will introduce.
Roses bloom beautifully with a long flowering period, and many flower enthusiasts like to keep a pot of roses at home for appreciation. They often propagate by cuttings after pruning. Now it's the cold winter, and many enthusiasts are eager to try cutting roses in winter, but are unsure if they can survive?
In fact, roses can be propagated by cuttings all year round. The reason why they are not propagated in winter is because the ambient temperature is too low, making it difficult for the cuttings to root. However, as long as the indoor temperature is above 18℃, the roses will still root and survive quickly after being cut. There is also a benefit to cutting roses in winter, which is that they are less likely to develop black stems due to the lower temperature, which reduces the chance of bacterial infection. 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's not suitable to propagate directly outside. It's best to find some small plastic cups or cut a plastic bottle in half and pierce a few holes in the bottom for drainage. You can also use a flower pot filled with loose and breathable potting soil to propagate roses, as long as it can be placed in a warm indoor environment.
Prepare cutting medium
When propagating roses, many people have encountered the phenomenon of cuttings developing black stems, which 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 cuttings, the choice of medium is very important. When preparing the cutting medium, you can mix vermiculite, perlite, fine coconut bran, etc., or use clean river sand directly, which can also have a good rooting effect.

Pruning branches
When pruning roses in winter, you can directly use the pruned branches for propagation. Choose a few strong branches, cut them into 10-15 cm cuttings, each with more than 3 bud points. Cut the bottom of the cuttings at a 45-degree angle to increase the absorption area. In winter, there is no need to retain the leaves at the top if there are no leaves.
Cutting treatment
If you are not confident in your propagation skills, you can sterilize and disinfect the pruned cuttings before propagation. Soak the cuttings in 0.2% potassium permanganate or carbendazim to sterilize them, then dip them in rooting hormone before propagation. This can effectively improve the survival rate of the cuttings.
Propagation method
Fill the prepared medium into the cultivation vessels, spray it slightly moist, and then insert the bottom of the treated cuttings into the medium, with a depth of about 3 cm. After inserting, you can cover the mouth of the bottle or the entire pot with plastic, pierce a few holes for ventilation, and place it in a weakly diffused light environment for care.
Avoid low environmental temperature
The key to whether the cuttings can survive in winter is whether there is a suitable ambient temperature. If the indoor temperature is below 15℃, the cuttings will not grow and will not root easily. You can cover the pot with a plastic bag to keep it warm and moist, which can help the cuttings root faster.
Even if the roses survive after being cut in winter, don't rush to repot them. The survival rate is very low at this time. It's best to wait until spring when it warms up and the cuttings grow a lot of new buds before repotting. This is more likely to ensure survival.
