How to propagate roses in autumn
This article introduces the experience of propagating roses in autumn and the fastest method for rooting cuttings in autumn. Let's learn about it together.
Roses are common potted flowers that not only have beautiful blooms but also carry good meanings, making them popular among flower enthusiasts. Roses are also easy to grow and propagate. Typically, a healthy branch is chosen, inserted into the soil, and can survive with a very high survival rate.
So how to increase the survival rate of rose cuttings? Below is an introduction to the complete process of rose propagation and the steps for transplanting after rooting.
Simple method for quick rooting of roses
1. Cutting Time
First, let's understand the timing for rose propagation. Roses can be propagated throughout the year, but September to October is a good time for rose propagation. The temperature during this period is between 20°C to 25°C, resulting in a high survival rate, with over 95% survival.
2. Preparations
Before propagating roses, prepare the materials needed for the process, such as the soil for propagation, the branches to be cut, the containers for propagation, utility knife, clean water, trays, and you can also prepare rooting powder.
3. Soil Preparation
For rose propagation, vermiculite can be used as the soil. It's best to rinse the vermiculite with clean water first and keep it slightly moist before use. For the containers, transparent disposable cups are used, which need to be treated simply. Generally, a red-hot screw is used to poke holes in the bottom of the disposable cups to allow for air and water permeability.
4. Branch Selection
For rose propagation, select robust branches and cut the long branches into segments, with each cutting having 2-3 buds. Remove the leaves from the branches, leaving only 1-2 pairs. The cut ends of the branches need to be cut smooth with a utility knife.
You can make a 45-degree diagonal cut to increase the contact area between the branch and the soil, making it easier to absorb water, or you can make a straight cut, which has a smaller wound area and heals and roots more easily. Choose the appropriate cutting method according to personal habits.

5. Filling Soil into Containers
Before propagating, fill the soil into the disposable cups. First, place the disposable cups in a tray and then pour the vermiculite into the cups. Then, water the cups filled with vermiculite until water comes out from the bottom of the cups.
6. Propagation Process
First, use a stick similar in thickness to the branch to insert into the vermiculite and wiggle it slightly to expand the hole. Then insert the rose branch into the hole, with a depth of about 2 centimeters. There's no need to insert it too deep. After one is done, proceed with the other branches in the same way.
7. Post-Propagation Care
After all the rose branches are inserted into the vermiculite, water them again to make the branches adhere more closely to the vermiculite and avoid any gaps. Then move the pots to a well-ventilated area. During later care, if the water in the tray dries up, replenish it in time to prevent the branches from dehydrating.
Also provide moderate sunlight, about 50%-70%, avoiding complete shade or direct sunlight. If the ambient temperature is too high, you can spray water around the pots.
8. Rooting
After about a month of care, you can see white roots through the cup walls. Don't rush to transplant when you see white roots. Wait until you can see fine roots all around the cup walls, then you can proceed with the transplant.
Try not to remove the soil during the process, as this can damage the roots and greatly reduce the survival rate of the transplant.
9. Transplanting
When the roots are fully grown, consider transplanting. Prepare the growing medium, flower pots, and the new rose plants with strong roots.
The transplanting soil is mixed with vermiculite, perlite, and coconut fiber in a 1:1:3 ratio. Fill the soil into the flower pots, filling 1/2-1/3 of the pot and pressing it down slightly.
Then use small forceps to hold the rooted rose plant and place it in the center of the pot, making sure the roots are fully spread out. Fill the soil on top of the roots without pressing too hard, keeping it natural. After planting all the new rose plants, water them thoroughly until water comes out from the bottom of the pot. If the soil sinks, fill it with more soil.
Finally, place the pot in a well-ventilated area and provide some sunlight. If the sun is not too strong, you can place it outside. Also, water the plants according to the dryness of the soil to prevent the seedlings from dehydrating.
