I will guide you through a special cutting formula combining coffee and onions. If you want to propagate roses at home but do not know how to quickly root branches, make new shoots grow strong, and prevent root rot, this method will help. Here is how I do it.
1. Why Coffee and Onion Rose Propagation Works
Coffee contains caffeine and many antioxidants. Caffeine helps stimulate the activity of callus tissue at the base of the branch, promoting cell division and the formation of new roots. This is why brewed coffee is a powerful base for rooting.
Onions contain sulfur compounds, flavonoids, and a small amount of natural phytohormones. These substances have strong antibacterial and antifungal effects, helping to prevent root rot while stimulating the callus at the base of the branch to develop new roots. Coffee and onion together create a rooting solution that both protects and stimulates.

2. Coffee and Onion Rose Propagation Setup
Coffee extract
Put 1 teaspoon of coffee in a clean glass jar and add 0.5 liters of boiling water. Cover and let it cool for about 1 hour.
Prepare cuttings
Choose a healthy branch with moderate age, not too young to avoid rotting and not too old because it is easy to dry. Cut the branch to about 15 to 20 cm, remove all the leaves and sharp thorns, keeping only a few clean stems. This step helps reduce water loss so the branch can focus its energy on forming roots.

Onion solution
Use onions about 30 grams. Cut the onion into thin slices, put it in a clean plastic cup, add 0.5 liters of water, and stir well. Soak the rose branches in this solution for about 30 minutes.
Tools and support
Prepare a clean glass jar and a piece of foam. Cut the foam to fit the mouth of the jar, then use a stick to make a small hole in the middle just right for the diameter of the rose branch. Have a string ready to secure the cutting.
3. Step by Step Coffee and Onion Rose Propagation
Filter and combine
After soaking for 30 minutes, take out the flower branches, filter out the onion residue, and keep the clear water. Filter the coffee through a clean cloth to remove the grounds. Mix the two solutions together to create a rooting blend that is both antibacterial and growth stimulating.
Position the cutting
Pour the mixed solution into the jar, almost full to the mouth. Place the foam on top of the jar and use a string to secure the position of the branch on the foam. Insert the branch through the small hole so the base is deeply immersed in the solution.
Create humidity
Cover the mouth of the jar with a plastic bag or a transparent plastic cup. This creates a high humidity mini greenhouse that helps the branch quickly take root. Place the jar in a cool place away from strong sunlight and wind.

4. Signs of Success and Potting Up
After just 7 days you will see green shoots start to grow and new white plump roots appear around the base. This is a clear sign the branch has successfully taken root. Move the branch to a larger pot using a well drained substrate such as coconut fiber so the roots grow healthily and the plant adapts quickly.
Final Thoughts
With just coffee and onions, two cheap and easy to find ingredients, we have created an effective natural cutting solution. This method stimulates strong root growth and protects the branch from root rot, helping you successfully propagate roses at home. I wish you success and a brilliant rose garden all year round.
