Petunias may be grown from seed by most gardeners. Planters and hanging gardens benefit from their strong, long-lasting blossoms. Taking petunia cuttings might be an option. Find out how to propagate petunia clones from cuttings, and you’ll be able to have a head start on the rest of your neighborhood when it comes to blooming time.
Why Propagate Petunia Cuttings?
It’s not easy to save petunia seeds and plant them again the following year if you want to grow the same variety of petunia. If you live in the northern portion of the United States, you may not see any flowers on your petunia plants until the middle of July. Second, if the petunias you grow and care for are hybrids, the seeds you collect will not produce real flowers the following year. Rooting petunia cuttings is the best strategy to increase the number of plants in your garden for next year.

Since I no longer have a source for inexpensive six-packs of annuals, I’ve had to rely on grocery store options and even Wal-Mart for petunias. This year, my petunia seedlings failed, but I’m planning to start some new ones soon. Hopefully.
So, I decided to get started with what I already had and make more of it. You won’t get full, lush plants out of this method in a hurry. To get the most out of the flowers, you’ll have to wait until the end of the season (unless you start in February). However, the reward is worth the wait..
You can start petunias from cuttings in the middle of summer when you prune or renovate your leggy petunias.
Propagate petunias: Sowing seeds yourself
Plants can be easily propagated by sowing. There are specific stores where you may buy the seeds. Generally speaking, there is a wide variety of options to choose from. Petunia seeds can be harvested from your own plants if you already have them. “Salmon Wave,” a salmon-colored cultivar, is exceptionally easy to grow from seed and even rainproof.
Harvesting seeds yourself
The seeds of petunias can be easily gathered by the user themselves. To do this, proceed as follows:
- The seeds of petunias can be easily gathered by oneself. Proceed as follows to accomplish this:
- When the seed capsules have turned a light brown color, remove them from the ground.
- Dried till they explode in a hot, well-ventilated area
- Keep little, black seeds in a cold, dark area for future use (e.g., screw jar)
Once you stop washing the seeds, they will begin to create seed capsules on their own. After a few days, the dried seed capsules begin to burst open.
Sowing the seeds
From February through March, seeds are sown. Observing a few simple rules, you’ll soon be able to enjoy tiny seedlings of petunia.
- Sow the seeds in a germ-free sowing soil in the tray.
- Mix seeds with sand and scatter them over the soil evenly and at an appropriate distance apart.
- At the very least, cover seeds with a thin, porous layer of soil (light germination)
- Minimum temperature for germination is 20 degrees Celsius.
- Spray the soil with a watering can to keep it equally hydrated (water sprayer)
- Wrap a foil hood around the seedling tray (ventilate 1x daily from germination)
- Location that isn’t under direct sunlight yet is nonetheless bright
- Prick out or transfer individual plants from the second pair of leaves.
- Before they are planted outside, the plantlets need to be acclimated.
- After the middle of May, you can start planting outside (no more danger of frost)

To speed up the process of planting micro seeds, you can add quartz sand to your mix. Mold can be minimized by placing a thin layer of dirt on top of the seeds. The foil cover acts as a humidity source. Place the plantlets outside during the day on sunny days to acclimate them. See our post on growing petunias for further information on where to plant petunias beginning in May.
If you want to get the most out of your petunias, keep in mind that they are supposed to bloom from June until the first frost, but many plants are fatigued by their own pace and fade before then. Some seeds can be sown later (in April or May) in order to prevent a flowerless season.
Propagating petunias by cuttings
Hanging petunia cultivars are ideal for cutting propagation since they develop long, vigorous shoots with sufficient care. Developing roots on your cuttings shouldn’t take long if you follow these steps.
- When it comes to cutting care, summer is the ideal time.
- Use 10cm long (ideally flowerless) stems for this purpose.
- Remove all of the blooms and foliage (except the top pair of leaves)
- As soon as the roots have formed, either place them in a glass of lime-free water, or plant immediately into the pots.
- When the cuttings sprout at the top, the propagation was a success.
- Continue cultivating as mature petunias in larger pots.
- Before planting in mid-May, acclimatize the cuttings.
In a glass of water, cuttings may take two to three weeks to develop enough roots to be useful. A few inches of dirt should be inserted into the pot and then pressed down firmly to ensure that the cuttings are well rooted.

Petunia varieties: A small selection
There are a wide variety of petunias to choose from. Both the flowers themselves and the hues in which they bloom are as diverse as the species itself. They also come in different forms. There’s a flower for everyone, whether you prefer single or double blooms. Four categories of variety are commonly used to classify the many kinds.
- Flowers are two to three centimeters in diameter on this multiflora.
- Rain-resistant multiflora with flowers that are around five centimeters in diameter.
- Floribunda with eight-centimeter-long blooms
- Large, trumpet-shaped, rain-sensitive flowers of the Grandiflora.
Below is a list of particularly beautiful petunia varieties
- This hanging petunia’s huge purple petals resemble a night sky dotted with white stars. There is no such thing as a duplicate flower.
- Chocolina: The chocolate-colored blossoms of this kind are enticing, but please don’t eat them. It grows in a bushy, barely drooping fashion.
- Double flowers and hanging growth characterize the Piroutte Red, a member of the Piroutte Red family. The red-eye has a lovely white rim around it.
- Amore Queen of Hearts: The name of this upright variety says it all: each of its red hearts on a yellow background sends a message of love.
- Mirage Red Morn: With its red-edged petals with a white eye, this upright petunia brightens any bed.

Prepare pots of soil
Filling up a six-pack container with potting soil and watering it thoroughly was all that was needed. I’ve been using these 2- to 3-inch plastic pots from Amazon for cuttings for over a decade and they’re still going strong.
The 6 pack container was the closest thing to them, but I was in a rush and didn’t utilize them this time.
Choose Petunia to take cuttings from
One of my petunias is ready for cuttings today. I picked up a four-pack of these at Wal-Mart for $3. Having bought them in the beginning of April, I potted them up and waited for them to reach a size where cuttings could be taken.
There is a second video in the film where you can show me taking cuttings from it as well. This essay concludes with a video showing the entire process step by step.
Choose stem to cut
A long stem is what you’re looking for. 3 to 4 inches is the ideal length for potting medium. My potting soil recipe is available here.
The petunia’s tallest stalk bears the largest flower, which is currently in bloom. I don’t want to chop it off since it’s so beautiful, but it’s inevitable.
Find a location just below a leaf node and follow it all the way down.
Take your Cutting
Just below the leaf node, use bypass pruners or any cutting tool of your choice.
Remove leaves from petunia cutting
Remove the leaves and side shoots from the petunia cutting and place it on a flat surface or potting bench.
You can either pinch them off with your thumbnail or cut them off with a sharp knife.
If you remove the exquisite leaves and flowers, it appears fairly sad, but this little cutting will quickly sprout new growth and subsequently more lovely blooms.
Rooting Hormone or not?
Spritz it with rooting hormone at the base. Petunias benefit from the use of this rooting hormone. Rooting hormone may not be necessary for petunias, but I’ll give it a go and let you know if it works.
The rooting hormone can spread plant disease and/or fungus if it is dipped directly from the bottle. Rooting hormone is submerged to a depth of around an inch in this little glass votive.
Stick cutting into planting soil
Creating an indentation with a tool that is large enough all the way around. I used a sharpie because it’s thick enough to make a good-sized hole for the cutting.

Having damp dirt prevents the earth from collapsing after removing the sharpie.
Gently but firmly press the earth around the petunia cutting as it is slipped into the Sharpie-created hole.
There are currently three cuttings from two plants. The plants were still small, so I grabbed another petunia to finish the job.
Place in a cool place.
To prevent excessive drying of the cuttings, I cover the planting trays with these domed lids.
Some people believe that this promotes the growth of mold and rot, so they opt for a misting system instead. However, besides experts, who else has such a setup?
These lids have been fantastic for me because they are well-ventilated and have a good seal. To my disappointment, Amazon didn’t have the same same ones, however these are near. With almost a decade of abuse, mine have shown to be well worth the money. Over the years, I’ve noticed that the color of my skin has changed.
Since it’s still cool outside, I put the cuttings in the greenhouse, but now it’s getting way too hot. In the summer, I’ll set them up on a table under my deck, where they’ll get plenty of light but won’t be baking in the sun.
Roots should appear within three to four weeks. You’ll get enough petunias to fill a tub or container before you know it.
This method of plant propagation can become addicting, so proceed with caution. Be forewarned!

How to Root Petunia Plants How to root petunia plants?
You should start with the best specimen of the plant in your yard and work your way down from there. Choosing plants with compact growth and bright, huge flowers in the colors you like will ensure that you’ll be generating perfect clones. During the fall, take cuttings from the plant. The process of rooting petunia flowers is remarkably simple if you follow the proper steps. Peat moss, sand, and plant food should be mixed together in equal parts. Spray the mixture into a flat to ensure it’s completely moist. Using a pair of scissors, remove the petunia plant’s delicate, flexible leaves off the crowns of the stems.
Until you can bring the leaves inside to plant, keep them moistened with a paper towel. Rooting hormone powder should be rubbed onto the leaf tips. Using a pencil, pierce the soil with the powdered stem and insert it into the resulting hole. Place soil around the stem to secure it. Keep a distance of about 2 inches (5 cm) between each leaf when you plant it. Keep it in a dark, cool area for about three weeks.
Check to see if roots have started growing on the stem by gently pulling on one leaf after this period has passed. Transplant the leaves into small pots once they have developed stems. Place the pots under grow lights on shelves and continue to cultivate them through the winter. First thing in the morning, you’ll have blooming petunias.
