How to Propagate Lisianthus? Detailed Guide to Seed Sowing and Cutting Methods

Lisianthus is a relatively common plant in people's daily lives, with high ornamental value. Many people in China grow it, so how to propagate lisianthus is also a question people care about. What are the propagation methods for lisianthus? Below, the editor will walk everyone through it.

I. How to Propagate Lisianthus / Seed Sowing / Cuttings

The question of how to propagate lisianthus can be roughly divided into two types: seed sowing and cutting propagation. As long as the methods are mastered, the survival rates of these two propagation methods are relatively high. Below is a detailed explanation of lisianthus propagation methods. Let's take a look.

II. Propagation Methods for Lisianthus

Seed Sowing Propagation

1. Soil Selection

Among the propagation methods for lisianthus, seed sowing is one of the simpler ones. When carrying out seed sowing propagation, we first need to choose soil. We can choose soil with good looseness, which will have better drainage and will be more conducive to lisianthus absorbing nutrients.

2. Sowing Method

After the soil is selected, we need to first disinfect the soil to prevent it from carrying pathogens. After disinfection is complete, we can sow. We can evenly scatter the seeds on the soil surface, then cover them with about 2cm of soil, then water thoroughly and let sit for about 15 days, after which they should basically germinate.

3. Follow-up Management

After germination, we can carry out normal care. For specific care methods, everyone can refer to the article on lisianthus cultivation methods, which has detailed instructions. The editor will not introduce them one by one here.

Cutting Propagation

1. Choosing Cuttings

When choosing cuttings, we can select relatively robust branches, as such cuttings will have a relatively higher survival rate. Also, after selecting the cuttings, certain pruning is needed. Generally, about half of the leaves on the branch can be removed, which can reduce nutrient consumption.

2. Choosing Substrate

After choosing the cuttings, we need to choose the substrate. We can choose a slightly alkaline substrate. After choosing it, we also need to use carbendazim to disinfect the substrate, which can prevent the breeding of viruses.

3. Cutting Method

After completing the preparatory work, we can carry out the cuttings. We can first use chopsticks to poke a small hole in the substrate, then insert the cutting, then press the substrate flat and water thoroughly. Generally, roots will form in 3-4 weeks. After rooting and sprouting, we can carry out normal care.

How to Propagate Lisianthus, Seed Sowing and Cutting Propagation Methods

How to propagate lisianthus: Lisianthus can be propagated by seed sowing and branch cuttings. Next, let's learn about lisianthus cutting and seed sowing methods separately.

Be sure to select relatively robust ones from mature plants, as this can effectively increase the success rate.

First choose the planting soil, then use a stick to poke a hole in the soil and place the cutting in, then bury it firmly with soil, then water thoroughly, and finally cover the top layer with plastic wrap.

To maintain breathability, poke a few small holes in the plastic wrap, then place it in a bright place. After about a week or so, the wrap can be removed, and after a month, you will find that the cutting has rooted.

For sowing lisianthus seeds, the soil is generally selected mainly with peat, then add a little perlite and other soil with relatively large particles, which can increase water permeability and breathability, and then add some disinfectant for disinfection.

After scattering the seeds into the planting soil, there is no need to cover the seeds with a layer of soil. Generally, the germination temperature needs to be controlled at around 24 degrees Celsius, and after about half a month, you can see the seeds grow sprouts. After germination, keep sufficient sunlight, and the potting soil should be slightly moist but not waterlogged.

When lisianthus slowly grows four or five leaves, it can be planted. When planting, you can plant several together, so that when lisianthus blooms later, it will look very beautiful. Generally, a flower pot with a diameter of about 21 cm can hold five lisianthus plants. After lisianthus is potted, be sure to remember to fertilize, which helps development.

How to Take Cuttings of Lisianthus? Cutting Propagation Methods for Lisianthus

The most commonly used method for propagating lisianthus is seed sowing. In fact, in addition to seed sowing, cutting propagation can also be used. However, because many flower enthusiasts did not master the correct method when taking cuttings, the survival rate after lisianthus cuttings is not high. Below, we bring practical lisianthus cutting propagation methods for all flower enthusiasts, which can effectively improve the survival rate.

I. Material Selection

Choose the part of lisianthus with strong meristematic ability. It is best to choose the stem below the second pair of leaves under the heart leaf after jointing, as its meristematic ability is stronger, so choosing a good cutting is very important. The stem below the first pair of leaves under the heart leaf is relatively tender and has relatively high nutrient requirements, so the survival rate is slightly lower. It is best to select cuttings with only one pair of leaves, and the survival rate will also increase.

II. Cutting Treatment

Cut the cutting diagonally into small sections containing one pair of leaves. The purpose of diagonal cutting is to increase the meristematic tissue area of the cut surface. Then cut each leaf in half, because at the beginning of cutting, since the cutting has no root system, the nutrients needed are all from the original reserves. Cutting off half of the leaves can reduce nutrient consumption and is more conducive to rooting. But do not cut off all the leaves, because then the cutting cannot carry out photosynthesis and cannot produce nutrients.

III. Preparing the Substrate

Choose a slightly alkaline substrate, maintaining the pH value at 6—6.5. You can use peat plus some vermiculite and perlite, add some carbendazim and stir, then disinfect the substrate to prevent the breeding of pathogens. Before sowing, water the substrate thoroughly to keep it moist.

IV. Specific Steps

1. Use chopsticks or a wooden stick to poke a small hole in the potting soil, and place the cutting in;

2. Use your hands to press the potting soil firm, and water thoroughly;

3. Cover with plastic wrap or a transparent lid, and poke a few small holes in it for ventilation;

4. Place the flower pot in a bright but not high-temperature place. In winter and early spring, it can receive direct sunlight;

5. After 10 days, the plastic wrap or plastic lid can be removed. In 3—5 weeks, the cutting can root. Once rooted to a certain extent, the aboveground part will begin to sprout new shoots;

6. When the new shoots grow their second pair of leaves, they can be transplanted, and at this time normal care work can be carried out.
    The above is an introduction to the cutting propagation methods for lisianthus. Lisianthus prefers a warm, humid environment with sufficient sunlight, is relatively drought-tolerant, and is not tolerant of waterlogging, so everyone needs to pay special attention during the care process.
