You can learn how to propagate potato vine in one of two ways. To propagate more Solanum laxum, this article will explain how to do so through cuttings and by layering. Note, however, that you may apply these same methods to the sweet potato vine, another lovely annual plant you can grow in your garden.
Seedlings of potato vines can be started in a greenhouse to speed up the germination process. Remember that stable, controlled conditions make setting up shop much simpler. This will ensure healthy seedlings for later transplanting.

How To Propagate Potato Vine Successfully
Method #1. Cuttings
As was previously noted, cuttings can be used to start new potato vine plants. If you wish to start new sweet potato vines, you can use the same method. Anyone familiar with cutting propagation should have no issue growing plants from potato vine cuttings.
Site preparation
Cuttings can only be successfully taken once the place or container has been properly prepared. If you wait too long after taking the cuttings, they will dry out and become damaged. Either use peat moss and sand to fill a well-draining container, or amend the soil in your garden to make it healthy and well-draining.
Cutting preparation
To prevent the mother plant from experiencing any stress, you should choose a robust specimen from which to make your cuttings. If you grow potato vine in a controlled setting like a greenhouse, you should be able to get cuttings from healthy parents. More so, be sure the samples you took were disease-free.
Cut a 4-inch segment of the potato vines just above the leaf using a clean, sharp knife. Leaves at the bottom two-thirds or bottom half of each cutting should be removed in preparation for roots. The ends of the sections should be dipped in rooting hormone before being planted, just as you would do with any other plant.
Rooting
If you’re planting cuttings in a garden, you can either place one in each pot or leave some distance between them. To prevent any leaves from touching the ground, you should compact the medium surrounding each cutting. Then, keep the soil moist by misting the cuttings of the potato vine.
Transplanting
Once new growth appears, you can cut back on watering to avoid root rot. Wait until the soil has dried up and the plants’ roots have grown to about an inch before watering again. This process can take many weeks, but once it’s complete, the potato vines are ready to be moved.
Method #2. Layering
Wrapping
Layering propagation is another option for these decorative vines. Most gardeners prefer this method because it’s easier on their backs and arms. To grow a vine indoors, fill a pot with potting soil and wrap the soil-covered end of the vine around the inside of the pot.
Burying
Make sure that you are burying the vine with the soil and then secure it into place. One must ensure that the vine remains buried in the soil to promote healthy root growth. Roots can only develop and maintain their moisture balance in the dark.
Separation
Root establishment can be expected after few weeks, same like when establishing potato vines from cuttings. After many new shoots have appeared, the vine is ready to be cut away from the parent plant. Cut it off carefully so that you don’t harm the parent plant or the replication process.
Caring For Potato Vine
It is important to know how to properly care for vines to assure a harvest of robust plants. If you want to grow potatoes successfully, you need to bring your plants inside before the first frost hits. In addition, these plants should thrive in a sunny, somewhat shaded region.
Winter is a good time to cut back on watering, but it’s still important to keep the soil moist, especially in dry climates. Keep in mind that the potato vines in your container will need extra water as a result. If you want the fertilization process itself to result in flowers, use a high-potassium fertilizer and stop feeding at the beginning of fall.
As long as you don’t put your potato vine through stressful conditions, they’re easy to care for and maintain. Pruning and repotting are necessary maintenance tasks that keep them looking their best and keep them from becoming overcrowded.
ORNAMENTAL SWEET POTATO VINE PROPAGATION METHODS
When it comes to propagating the sweet potato vine (Ipomoea batatas), I recommend either rooting stem cuttings in water or soil, or dividing the plants.
These techniques can be applied to the multiplication of any species. You can use the same procedures with green, chartreuse, pink, black, or purple.
FROM CUTTINGS
It is possible to multiply a single plant by means of stem cuttings (also known as slips), which can be rooted in either water or soil.
Unfortunately, only stem cuttings will work, not individual leaves.
BY DIVISION
Also, you can divide mature Ipomoea batatas plants. Large sections of the rootball can be cut off, or the individual underground bulbs/tubers can be separated.
In order for the tubers to grow into new plants, the vines must reach full maturity. For this reason, this technique is only suitable for mature plants, although it is a fantastic choice for preparing them for the winter months.
FROM SEEDS
Although sweet potato vines can produce usable seed, they are notoriously poor bloomers. Therefore, this method of spreading them can be challenging.
Unfortunately, certain attractive kinds are sterile, so I can’t advocate this technique for home gardens.
WHEN TO PROPAGATE SWEET POTATO VINE
If you want to start new sweet potato vines indoors, you should do so in the spring or summer, before the weather becomes cold.
It’s also the best time for dividing them. However, if you live somewhere warm, you can do it in late summer or early autumn.
SUPPLIES FOR PROPAGATING IPOMOEA BATATAS
Additionally, now is the optimal time to split them up. However, if you happen to reside in a temperate region, you can accomplish this task in the waning days of summer or the first days of fall.
- Vegetables taken from vines
- Cuts with precision or shears for pruning
- Hormone that encourages roots to form
- Soil or water for planting roots
- An enclosure for the purpose of spreading a message (optional)
- Draining containers or a vase
- Spray cans
- Insulating pad for use in cold weather (optional)
- Garden fork or shovel
- To plant in a pot or in the ground
PROPAGATING SWEET POTATO VINE FROM CUTTINGS
Taking cuttings and rooting them is the most common way to multiply ornamental sweet potato vines. But first, we must discuss the steps involved in taking and preparing them.
HOW TO TAKE THE CUTTINGS

All parts of the plant, including the leaves and stem, will eventually produce roots.
You should pick healthy vines that are 6-12 inches in length and have several leaves for the greatest results. Then, make a precise incision with a clean pair of pruners or snips.
PREPARING IPOMOEA BATATAS FOR PROPAGATION
Pinch off the leaves from the bottom two-thirds of the stem to prepare your slips. It’s important to move fast, as the flowers will begin to wilt as soon as they are plucked from the plant.
Too much wilting can make roots more challenging. As soon as possible, plant or submerge them.
HOW TO ROOT SWEET POTATO VINE CUTTINGS
These detailed instructions will help you successfully root cuttings of sweet potato vines in either water or soil.
STEPS TO PROPAGATE SWEET POTATO VINE IN SOIL
The risk of transplant shock can be minimized and better, more resilient beginnings can be encouraged by rooting the cuttings in soil.
As high humidity is beneficial to their growth, a propagation chamber can be useful. One can either buy one or create their own.
The first step is to prepare the medium; I find that a mixture of equal parts peat moss, perlite, and vermiculite is the best for rooting cuttings and seedlings. However, a high-quality, well-draining seed-starting mix can also be used.
The second step is to prepare a container, such as a sterile pot or a propagation chamber. Put in a few inches of a pre-moistured medium. The desired consistency is evenly damp, not wet or soggy.
Step 3: Make holes — Using a pencil or your finger, create a hole in the medium for each stem.
Fourth, apply rooting hormone by dusting the stem bases. This is not required, but doing so will speed up the process and promote healthier, more evenly distributed roots.
Finally, step five is to bury the stems: place each slip into the dug hole and gently compress earth around it.
Step 6: Protect the soil and plant from light by covering it with plastic. Use the lid of your propagation chamber or a large plastic bag. Leaves will rot if plastic is allowed to come in contact with them.
Seventh, set the container on a heat mat (optional) to hasten root formation. Warm soil promotes rapid root growth.
The eighth step is to provide the cuttings indirect light rather than direct sunlight. Use either direct sunlight or partial shade.
Step 9: Never let the soil dry out; rather, keep it consistently moist. Until new growth appears, keep it damp, but not wet.
Use a spray bottle to wet the cuttings at the soil level often to prevent drying out or overwatering if you didn’t cover them with plastic.
STEPS FOR ROOTING SWEET POTATO VINE IN WATER
The decorative sweet potato vines that I grow are all the result of water propagation, which is my favourite method. They can stay submerged for considerably longer than most plants before they begin to rot, and they root quickly.
In any case, after they have solid root development, you should move them to a larger container.
First, fill a vase with warm water; ideally, this should be done in a transparent vase so that you can observe the development of the plant’s roots, but any jar or similar container will do.
Step 2: Put the stems into the water – Ensure that only the stems are submerged. If any part of the leaves are touching the water, they will rot.
The second step is to place the stems in the water, taking care to immerse only the tops of the plants. The leaves are doomed to rot if even a single one of them comes into contact with the water.
At first, you may see some wilting, but after a few days, they should begin to flourish.
In order to prevent decay, move on to Step 4 and maintain clear water at all times. Also, make sure the roots are always under water so they don’t dry out.
Fifth, give the roots time to grow to at least 3 inches in length before repotting them.
HOW TO PROPAGATE SWEET POTATO VINE BY DIVISION
The best way to get a lot of new sweet potato vines is to divide established ones. The mature plant’s tubers can be dug up and separated, or the rootball can be cut into pieces.
STEPS FOR DIVIDING THE TUBERS OR ROOTBALL
Be careful to give your ornamental sweet potato vine plenty of water before you divide it. If you want to split it, water it thoroughly at least 24 hours before you do.
As a first step, prune the plants (if you want to). Not required, but large vines can be a pain to detangle. Therefore, you might shorten them initially to a more workable size.

Third, dig a broad circle around the plant’s base to expose its roots and tubers without damaging them.
The fourth step is to remove any clumps of soil that may be in the way of untangling the roots.
Part 5: Tease the roots apart, dividing them up into large clusters or individual bulbs.
Prepare the soil by mixing in compost or manure with your garden dirt, or by purchasing a high-quality potting soil and watering it down for use in pots.
Plant them, as the seventh step requires – Backfill the soil or refill the pot to the same depth you dug the original plant out. Alternatively, you can plant individual tubers in the ground 1-2 inches deep.
Step 8: Maintain Soil Moisture: Maintain soil moisture until new growth appears, and then water normally. Your divisions may look a little sad after being transplanted, but they should perk up again in a few days.
HOW LONG DOES IT TAKE TO PROPAGATE SWEET POTATO VINE?
It doesn’t take very long to propagate sweet potato vines, the cuttings root very quickly. It takes just a few days for the roots to begin forming, and about 2-3 weeks for them to be long and hardy enough to pot up.
WHY WON’T MY SWEET POTATO VINE PROPAGATE?
Cuttings from sweet potato vines take extremely little time to root and are thus easily propagated. The roots start to form in just a few days, and by the time you’ve waited two to three weeks they’ll be long and sturdy enough to pot up.
Never let the roots dry out, but don’t overwater either, or the stems and tubers will rot.
As an additional factor, warmth is crucial. If you keep your residence on the cool side, a heat mat can be a lifesaver.
The correct time of year has come for you to take your cuttings. When fall’s chill sets in, the plant dies back on its own and new roots are nearly impossible to establish.
HOW TO CARE FOR SWEET POTATO VINE CUTTINGS
Simple maintenance is required during the rooting process. Humidity can be provided by covering the cuttings or by misting them often.
Also, make sure they have plenty of heat and light to work by. Put them in water or soil, and they may droop for a few days; this is normal. They will be OK in a few days.
HOW TO TRANSPLANT OR REPOT THE CUTTINGS
It’s time to pot up your cuttings when you detect new leaf growth or when the roots are at least 3 inches long.
Put together a potting soil that is both nutrient rich and free of excess water. Wet it down and bury the stems at the same depth you did when they were rooted.
Lightly water them and move them back into indirect light as they get settled in their new habitats. In the event that you notice any drooping or wilting, let the plants a few days to recover.
Conclusion
Add some flair to your garden with ornamental vining plants like potato and sweet potato vines. The good news is that the process of learning how to propagate a potato vine is straightforward and, with proper care, completely failsafe. The potato vine can be propagated by planting cuttings taken from a healthy parent plant.
The tip of a vine, however, can be encircled around a container and allowed to root before being detached from the parent plant. The major message is that the propagations should be set in a nutrient-rich, well-drained environment to promote root development. Growing them in a greenhouse can help you produce healthy transplants.
As long as you don’t put your potato vine through stressful conditions, they’re easy to care for and maintain. Pruning and repotting are necessary maintenance tasks that keep them looking their best and keep them from becoming overcrowded.
