Growing Nemesia From Cuttings: Tips For Rooting Nemesia Cuttings
By: Teo Spengler
Nemesiais a small bedding plant with flowers that look like small orchids, with alobbed petal fanning out on top and another large petal below. The flowerscover low, mounding foliage. If you have some nemesia in your garden and wantmore, you can try rooting nemesia cuttings.
Nemesia cutting propagation isn’t difficult if you know howto proceed. Read on for information about growing nemesia from cuttings.
Nemesia Cutting Propagation
Nemesia is the genus of a variety of pretty flowering plantsincluding some perennials and some sub-shrubs. All feature flowers with two“lips” and simple, opposite leaves.
These are easy plants to love, and many gardeners who have afew plants in the backyard decide that they would like more. While you can grownemesia from seed, many ask: “Can I propagate nemesia cuttings?” Yes, it isentirely possible to start growing nemesia from cuttings.
Nemesia cutting propagation involves clipping stems fromgrowing nemesia plants and putting the cut stems in soil until they root. At thatpoint, they form a new plant. You can start growing nemesia from cuttingswithout killing the original plant.
How to Root Cuttings from Nemesia
If you are wondering how to root cuttings from nemesia, itis pretty much the same procedure you would use to root other cuttings.However, there are a few specific details involved in the procedure for growingnemesia from cuttings.
You need to select the medium carefully when you startgrowing nemesia from cuttings. It must have excellent drainage and carry a pH(acidity level) of between 5.8 and 6.2.
Take stem cuttings about 4 to 6 inches (10-15 cm.) long.You’ll have the best luck with rooting nemesia cuttings if you plant thecuttings soon after take them.
Poke a hole in the medium with a pencil, then insert acutting, bottom first. Pat the medium around the cutting. Keep the temperaturebetween 68- and 73- degrees F. (20 to 23 degrees C.) until roots form at thebase of the stem.
At that point, keep the media moist but not wet and maintainbright light and moderate temperatures. You can transplant nemesia rootedcuttings about three weeks after the cuttings are planted.

Five great tips for starting new plants from cuttings
Even if you already know how to root a plant in water, you can make the process more successful with great tips from David Clark, professional horticulturist.
He also shares tips on two easy methods for starting plants that you may not have used before.
Clark recently gave two hands-on workshops on plant propagation at the Buffalo and Erie County Botanical Gardens.
He shared a wealth of information, including these five great tips:
1. Create a mini-greenhouse. How many times have you bought bedding or a comforter that comes packaged in a plastic zipper bag? I have many times, and I always think, “I should be able to use this bag for something.”
Roots will grow out of the nodes or bumps on the stem of this Wandering Jew plant.
Clark says these bags make great mini-greenhouses for rooting plants or for recently transplanted plants. Just pop the plant into the bag and zip the bag up partway. This will help keep in moisture. At the same time, having a small opening allows for airflow to prevent the growth of mold.
“I almost always root with a bag because, unless you have a greenhouse, the plant needs to be enclosed,” Clark said.
The bedding bags, as seen in the photo at the top of the story, can accommodate a large plant or several small plants.
2. Use rooting powders. One of the simplest ways to propagate plants is by placing a plant cutting in water. Cut the stem straight across above a node (see photo above). This method works well with soft, fleshy plants such as Wandering Jew, ivy, arrowhead plant and spider plant.
You can increase your chances of success by using rooting products, Clark said. Many commercial products are available. These products kill fungus and bacteria to prevent the stem from rotting, and contain a growth hormone to speed the formation of roots.
Pour out a small amount of powder and dip your stem into the powder. (Don’t stick the stem directly into the product container.) Let the stem set for a minute. The plant will absorb the powder. Stick the end of the cutting into water the water won’t wash off all the powder.
You can also use common household products to aid rooting, he said. Dip your plant stem into cinnamon to kill fungus and bacteria. To promote root growth, create a rooting solution by dissolving an aspirin in water.
3. Give your new plant time to acclimate from water to soil. If you root your cutting in water, it develops roots that are best adapted to get what they need from water rather than from soil, Clark pointed out. If you move the plant immediately from water to soil, the plant may be stressed.
Instead, add a small amount of soil to the water that you’re using to root your cutting. Do this slowly, over a period of four or five weeks, to help acclimate your plant to its new growing conditions.
Lissette Ruotolo of Amherst, a participant in the workshop, cuts the leaf into sections.
4. Discover leaf section propagation. If you have a succulent such as the sansevieria above, you can start new plants from the leaves. You don’t even have to use the entire leaf a section of leaf will do!
When you cut the leaf, make sure to note which is the top part of the leaf section and which is the bottom part, Clark said. Place the bottom part of the leaf section into a tray of moist perlite, as in the photo below left. (Interesting fact: perlite comes from volcanoes.)
You can use this process for other succulents such as Christmas cactus, too.
5. Encourage plants to propagate through runners.
Look at the photo of the Wandering Jew near the beginning of this article. Another way to propagate plants like this is to bury the stem horizontally. Baby plants will spring up from those nodes.
