How to propagate roses in autumn
Today's experience sharing: How to propagate roses in autumn and the fastest method for rooting cuttings, as well as some knowledge about flowers and plants, details are as follows:
Roses are common potted flowers, not only beautiful when blooming but also with good meanings, so they are loved by flower enthusiasts. Roses are also easy to grow and propagate. Usually, a healthy branch is selected and inserted into the soil to survive, with a very high survival rate.
So how to improve the survival rate of rose cuttings? The following is a complete guide to rose propagation and the steps for transplanting after rooting.
Simple method for roses to root quickly
1. Cutting Time
First, understand the timing of rose propagation. Roses can be propagated in all seasons, but September to October is a good time for rose propagation. The temperature at this time is between 20°C to 25°C, with a high survival rate, reaching over 95%.
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, tray, and optionally, rooting powder.
3. Soil Preparation
For the soil of rose propagation, you can choose vermiculite, which should be rinsed with clean water first and kept slightly moist before use. The containers used for propagation are transparent disposable cups, which need to be simply processed. Generally, a red-hot screw is used to puncture a few holes in the bottom of the disposable cup to facilitate ventilation and water drainage.
4. Branch Selection
For rose propagation, choose strong branches and cut the long branches into sections, with each cutting containing 2-3 buds, removing the leaves, keeping only 1-2 pairs of leaves. The cut ends of the branches need to be cut smooth with a utility knife.
A 45-degree oblique cut can be made to increase the contact area between the branch and the soil, making it easier to absorb water, or a flat cut can be made, which has a smaller wound area and heals and roots more easily. Choose the appropriate cutting method according to personal habits.

5. Soil Filling
Before propagation, fill the soil into the disposable cups, first placing the cups in a tray, then pouring vermiculite into the cups. Then, water the cups filled with vermiculite until water flows out from the bottom.
6. Propagation Process
First, use a stick similar in size to the branch to insert into the vermiculite and sway it slightly to expand the hole. Then insert the rose branch into the hole, with a depth of about 2 centimeters. After inserting one branch, continue with the others in the same manner.
7. After 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 air gaps. Then move the pot to a well-ventilated area. During later care, if the water in the tray dries up, replenish it promptly to prevent dehydration of the branches.
Also provide moderate sunlight, about 50%-70%, avoiding complete shade or direct sunlight. If the ambient temperature is too high, you can mist the area around the pot.
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 wall before transplanting.
Avoid transplanting too early, as it can lead to incomplete roots and lower the survival rate of the transplant.
9. Transplanting
When the roots are fully grown, consider transplanting. Prepare the growing medium, flower pot, and the new rose plants with strong roots.
The soil for transplanting is mixed with vermiculite, perlite, and coconut bran in a ratio of 1:1:3. Fill the soil into the flower pot, filling 1/2-1/3 of the pot and pressing it down.
Then use small tweezers to hold the rose plant with roots and place it in the center of the pot, making sure the roots are fully spread out. Fill the soil around the roots, but don't press too hard, keeping it natural. After planting all the new rose plants, water thoroughly until water flows out from the bottom of the pot. If the soil subsides, add more soil.
Finally, place the pot in a well-ventilated area and provide some sunlight. If the sun is not strong, you can place it outside. Also, water according to the dryness of the soil to prevent the seedlings from dehydrating.
The above is an introduction to how to propagate roses in autumn and the fastest method for rooting rose cuttings, which can be used as a reference suggestion.
