Plant propagation is a cheap and easy way to get new plants from existing ones. It does not require much knowledge or skills to get several from a single sedum. Read about the methods of breeding sedum in our article.
Sedums reproduce in several ways. Two-year-old plants are suitable for propagation by dividing and cuttings. Sedum has to be at least three years old to multiply with seeds because they only start to bloom in the third year. Let's look at each method of propagation of this succulent in more detail.
Propagation by Division
The easiest and most effective way to propagate sedum. Adult healthy plants are suitable for propagation in this way. The best time of year for the division is early spring. It is important to be in time before flowering.
To propagate with this method, you need a small shovel and a clean, sterile knife.
- Dig the sedum out of the pot. Try not to damage the roots with a shovel.
- Inspect the roots of the plant. If you see any diseased or dried out parts of the roots, remove them.
- Select branches with buds and several roots. Separate them from the parent bush with a knife.
- The cuttings should be even. Process the places where the cuts are made.
- Immediately after dividing, plant branches in loose soil. If this is not done, they may dry out.
- The depth to which new branches need to be buried should be the same as the depth of planting of the parent bush.
- After planting, cover the soil with mulch. This will retain moisture in the soil.
- Place flowerpots in a light, warm room. Preferably without exposure to direct sunlight.
Propagation by Cuttings
This type of propagation is good because it can be carried out at any time of the year when the sedum does not bloom. As well as for reproduction by division, strong adult plants should be chosen.
This method may seem cruel to the plant from the outside. It is even useful for sedum. By losing the tips of its branches, the plant becomes thicker and stronger over time.
You will need a sharp, clean knife to carry out the propagation with the cuttings.
- Prepare the soil for planting the cuttings. Mix sand and peat in equal proportions. Place pebbles at the bottom of the pot as drainage.
- Choose strong healthy branches from which you will cut off the tops. The longer the parent branch, the longer the cut should be.
- Before cutting, make sure that there are at least a few leaves on the future section. After cutting, remove the lower leaves from the branch.
- Dip the cut first in water and then in a root stimulant. Then gently stick the stalk 1/3 into moist soil.
- A clear glass container filled with clean boiled water can be used instead of the soil. After the roots have formed, the sedum is transplanted into the soil.
- Water the sprouts daily. At the same time, monitor their condition and prevent rotting and mildew.
- Root formation takes about two to three weeks. Gently pull the sprout to check if rooting has begun. If it does not give in, it has started to develop roots.
Propagation by Leaf Cuttings
It's the most fertile way to reproduce sedum. It doesn't depend on the height of the plant. One sedum can produce dozens of new plants.
Some succulent species multiply with leaves on their own. They drop them on the ground, where the leaves take root and turn into new plants. If your sedum does not drop the leaves on its own, follow the instructions below:
- Inspect the plant, choose only healthy leaves. Cut them off with a clean, sharp knife.
- The cut-off leaf should contain part of the stem.
- Treat the place of cut with a root stimulating agent.
- Some gardeners recommend inserting the leaf into the soil. Others find it sufficient to simply place the leaves on the ground surface. Both methods have proven to be effective. You can find out which one is suitable for you experimentally. Insert half of the leaves into the soil, half spread on its surface.
- The bottom layer of the soil should consist of pebbles. This will provide the necessary drainage.
- Place the soil tray in a warm, bright room. Try to avoid direct sunlight on it.
- Use a spray to provide proper soil moisture. The water should be clean and warm.
- The container can be covered with a clean, plastic film for a more comfortable environment.
- After 2-3 weeks, roots and new shoots will appear on the leaves. You can then remove the old leaf and transplant the sprout into a separate pot.
Propagation by Seeds
This method of sedum propagation is the longest. It requires preliminary preparation and a lot of patience. So it is not suitable for all lovers of succulents.
It's also characterized by uncertainty. Unlike other propagation methods, this method does not guarantee that the same plant will grow from the seed as the parent. This can happen with some hybrid sedums.
Seed size can be another challenge for seed propagation. They are very tiny, light, and require careful handling.
The easiest way is to buy seeds in the store. But if you have flowering sedums, you can collect and plant the seeds yourself:
- Wait until the plant has finished blooming. When the seedheads turn brown, cut them off.
- Put the seedheads in a paper bag and store them in a cool, dry place. In a few weeks, the seeds will get dry and ready for planting.
- Take out the seeds and sift through a fine screen. This will get rid of the garbage.
- Put the resulting seeds in a plastic bag. Sign the name of the sedum and the date of packing.
- In six months, the seeds will be ready for planting. If you have collected them in the fall, you can start sowing in spring.
- Use high-quality soil of fine fraction. You can add sand to it. The soil should be damped before sowing. Don't forget about the drainage.
- Insert the seeds into the soil with a little pressure. Keep a sufficient distance between them.
- Some gardeners recommend covering the seeds with another thin layer of soil. Others, on the contrary, say that sowing doesn't need any additional coverage. Experimentally, you can find out which method suits your seeds best.
- The container with the planted seeds can be covered with a clean, plastic film to keep it moist. Once a day, it should be removed to ensure air circulation.
- The tray should be placed in a warm room without direct sunlight.
- Keep the soil moist with a sprayer until germination begins.
- Sprouts should begin to appear after two or three weeks. After that, you can stop covering the container with a film.
- Gradually increase the amount of sunlight that falls on the sprouts.
- Once the seedlings are large enough, transplant them into individual flowerpots.
