Multiply gloxinia - This is how it works by division, seed sowing and cuttings

It is an exciting challenge not just to buy gloxinias in specialist shops, but to use them yourself. It's even easier than expected.

Multiplying gloxinias (sinningia) is a breeze. In addition, there are several options available to you, because gloxinias can be propagated by division and also by cuttings and seeds. All three methods are promising. We would now like to explain to you in more detail how exactly you have to proceed with each method.

Multiplication by division

Here we are dealing with a simple method, which can also be carried out by inexperienced hobby gardeners. Because before winter, the plants withdraw into their bulbs. Before taking the plant to the winter quarters, you can divide the garden gloxinias. In the case of the gloxinia cultivated as a houseplant, the upcoming repotting in spring is a good opportunity to divide the tuber.

Instructions for propagation by division

You need:

  • sharp knife
  • substratum
  • pots

Here's how to do it:

  1. Take the bulb out of the ground or out of the plant pot.
  2. Wipe off the excess earth.
  3. Now divide the tubers with the knife.
  4. Then let the sections dry.
  5. If the interfaces have dried well, then have sandy substrate ready.
  6. Now place the individual segments in separate planters.
  7. The rooting should then take place at temperatures above 20 degrees.

Use sharp and sterile knives when dividing, so that straight cut edges are created and the plant is not unnecessarily injured. In addition, leave the interfaces as small as possible, because open wounds make the plants vulnerable to diseases and pests. Before you plant the divided tuber again, the cut should be well dried. The best way to do this is in an airy place outdoors. In order to minimize the risk of invading fungi and pests, it is also advisable to apply carbon powder to the interfaces.

Propagation by cuttings

This method is also quite simple, although it requires a lot of patience until the cuttings develop strong and, above all, flowerable plants. If you use late summer to harvest cuttings, with a bit of luck you will grow flowering plants until next spring. But don't rely on a cutting. Not every propagation succeeds. You play it safe with several cuttings.

Instructions for propagation through cuttings:

You need:

  • cuttings
  • sharp, germ-free knife
  • potting soil
  • pots
  • Bewurzlungspulver
  • plastic cover

Here's how to do it:

  1. Cut vigorous leaves from the plants.
  2. Then put the cuttings in the soil.
  3. Now use rooting powder.
  4. Then place the plant pot warm and bright and cover it with a plastic hood.
  5. Then water the cuttings regularly.

If temperatures of around 25 degrees prevail, the first new shoots appear after half a year at the latest. This is a sure sign of successful propagation. You can then place the young plants in larger planters or outdoors and cultivate them like adult plants.

Propagation by seeds

If you already have gloxinias in your possession, it makes sense to try to propagate them by sowing. On the other hand, if you want to get the semen in specialist shops, it is not always easy. Gloxinias are mostly sold as tubers and not as seeds. However, the seeds are very fine and sowing requires a great deal of tact.

How can the seed be obtained?

If you always remove faded food immediately, you will not be able to extract seeds from existing plants. The seeds have to ripen first. You should therefore leave faded things on the plant. The seeds can then be harvested around September. Then they have to be dried. You can then sow them in early October. You can also sow the seeds from late winter.

Instructions for propagation by seeds

You need:

  • seed
  • potting soil
  • planter
  • Foil or glass sheet
  • pots

Here's how to do it:

  1. Sprinkle the seeds on commercially available growing soil or cactus soil.
  2. Press the seeds lightly. Do not cover with earth!
  3. Now cover the plant pots with foil or a glass hood.
  4. Place the plant pots in a bright and warm location (approx. 25 degrees).
  5. So that the seeds do not go moldy, air the plant pots daily.
  6. Also regularly moisten the seeds with a flower sprayer.

Once a few leaves have developed, you can put the young plants in your own planters. Further cultivation takes place at temperatures around 15 degrees. It takes around three years for the first flowers to appear on the home-grown plant.

Overview of the advantages and disadvantages of the individual methods

❍ division:

+ Advantages:
Propagation by division takes place quickly and easily. In addition, the division can be carried out as part of transplanting. After division, the individual segments are transplanted and grow into independent plants in a short period of time.

- Disadvantage:
A sufficiently developed plant is a prerequisite for the possible division of the tuber. If you do not work with a sharp and sterile cutting tool, germs can penetrate the tuber.

❍ cuttings:

+ Advantages:
Cuttings can easily be obtained from existing plants. Several young plants can be grown with little effort. Recommended reading: Planting Gloxinia - This is how it can be grown in the home and garden.

- Disadvantage:
It can take up to half a year for the cutting to take root and start to sprout again. Constant high temperatures of around 25 degrees are also required for rooting.

❍ seeds:

+ Advantages:
You can get the seed from existing plants. This will result in numerous new plants.

- Disadvantage:
Gloxinia seeds are relatively difficult to obtain commercially. The seeds are also very fine and should be handled with care. The temperatures should not drop below 25 degrees during germination. It takes several years before the seed becomes a flowerable plant.
