Here is an extremely unique method of propagating roses – using onions. Onion peels contain a lot of quercetin, natural sulfur, and antioxidants, which stimulate root cell growth and are also very strong disinfectants. This solution helps rose branches root faster and prevents microorganisms from causing root rot during the incubation process.
Apple peels contain a lot of malic acid, vitamin C, and polyphenols which help soften plant tissue, support nutrient absorption, and stimulate the growth of young roots. The combination of onion and apple peel creates a biological solution rich in natural enzymes that promotes the formation of callus tissue at the cut and initiates root growth in just the first few days. For a simple one-cup rooting method for roses, see this guide.
1. Onion Peel Rose Propagation: Prepare the onion peel infusion
Prepare 1 onion with the dry outer skin intact. Wash the onion to remove dirt, then gently peel off the outer skin – this skin is the main ingredient. Chop the onion skin into small pieces to increase the contact area, helping the active compounds in the skin dissolve in water.
Put the chopped skin into a clean glass jar, then pour in 500 ml of boiling water. Stir well and cover tightly. Let this mixture soak until completely cool.
2. Onion Peel Rose Propagation: Make the apple-onion enzyme mix
Prepare a medium-sized apple, wash it, peel it, and cut it into small pieces. Put all the chopped apple peels into a clean plastic cup. Take about 30 grams of onion, cut it into small pieces, and put it in the same cup with the apple peel.
Pour in 500 ml of clean water and stir well. This combination creates a biological solution rich in natural enzymes which helps promote callus formation at the cut and initiate root growth in the first few days.

3. Onion Peel Rose Propagation: Select and prep the cutting
Choose a healthy rose branch, free of pests and diseases and of moderate age – the stem has become slightly woody but is still flexible. Use scissors or a sharp pruning knife to cut off all the leaves, sharp thorns, and wilted petals. Shorten the branch to about 15-20 cm, and cut the base diagonally to increase the nutrient absorption area.
4. Onion Peel Rose Propagation: Soak the cutting
Immediately after cutting, soak the rose branch in the onion – apple peel solution just prepared. Soak for 30 minutes so that the solution penetrates the conductive tissues in the stem.
5. Onion Peel Rose Propagation: Build the rooting setup
Prepare a small, clean glass jar and a piece of foam. Cut the foam so that it fits snugly into the mouth of the glass jar. Use a small stick to punch a hole in the middle of the foam, equal to the diameter of the rose branch so the branch stands firmly without tilting or breaking.
6. Onion Peel Rose Propagation: Mix the rooting solutions
After soaking for enough time, filter out the residue of the onion – apple peel solution to collect the clear water. Take the onion peel solution from step 1 and mix these two solutions together to create a complete root nutrient mixture – both antibacterial and stimulating strong roots.
7. Onion Peel Rose Propagation: Assemble and place the cutting
Pour the mixed solution into a small glass jar until it is full. Place the foam on top, then cover the mouth of the jar to limit evaporation. Use a cable tie to lightly wrap around the middle of the flower stem to fix the position on the foam and help the branch stand firmly.
Insert the base of the flower stem through the hole in the middle of the foam so that the base of the stem is submerged in the solution about 3-5 cm. For more bloom after rooting, try this simple one-cup trick to boost blooms.
8. Onion Peel Rose Propagation: Create a humid microclimate
Use a transparent plastic bag or a plastic cup to cover the entire glass jar. This helps to maintain high humidity, creating an ideal microclimate for the rose branch. Place the jar in a cool place, away from strong winds and direct sunlight to prevent water loss and encourage easier rooting.
9. Onion Peel Rose Propagation: Check progress
After about 10 days, you will see the magic happen. On the stem, green shoots begin to sprout. At the base, plump, healthy white roots appear and grow around the entire cut – a sign the branch has fully absorbed nutrients and is ready to be planted in a pot.
10. Onion Peel Rose Propagation: Potting and early care
When the roots are about 2-3 cm long, gently plant the branch in a pot with a well-drained substrate, ideally clean, slightly moist river sand. In the early stages, place the pot in a place with diffused light and mist to keep it moist. After about 2 weeks, when the plant has completely taken root, move it to a place with more light for strong growth.
11. Onion Peel Rose Propagation: Why this natural method works
This method takes advantage of biological compounds in plants to stimulate roots, nourish branches, and fight bacteria without using chemicals. The mixture is safe and helps the rose branch develop roots quickly, thick and strong – the foundation for future seedlings to grow well and produce many flowers with bright colors. Try this recipe in your garden and enjoy the results that nature brings.
Final thoughts
Onion peels and apple peels, used the right way, can turn a simple cutting into a vigorous young rose. Wishing you success with pots of green roses, bright all year round.
