Begonia seeds can be collected in only two simple processes. When starting a begonia seed collection, this is a beneficial skill to have because you may use your existing plants. However, even if you don’t use this method, you can take advantage of the seedpods your begonias produce following their flowering time.

It’s a good idea to grow begonias indoors when it comes to propagation. Keeping in mind that some types of begonias have difficulty in specific climes, you’ll have a higher chance of beginning begonia seedlings in the greenhouse. Regardless of the type of plant, seed germination requires a stable environment.

How To Gather Begonia Seeds

Step #1. Harvesting

Keep an eye out for seedpods so that you can harvest them before they deteriorate. When the blooms begin to dry and wither, the plants should begin to produce them. Wait for the seedpods to dry completely before removing them from the plant; however, if you wait too long, they may split open, resulting in a loss of seeds.

Step #2. Drying and storage

The seedpods should be opened on a piece of paper so that they may be poured into a container more easily. Pour the seeds into a container with a tight-fitting lid once they’ve been funneled through the paper funnel. Wait one week before moving on to the next phase by storing your seeds here.

Your main goal is to leave you with viable seeds for planting after you have dried the seeds. Use two sheets of paper to make it easier to separate them. Finally, put the seeds in an envelope, seal it, and label it for the next year’s harvest.

How To Propagate Begonias

You may propagate begonias through stem cuttings, leaf cuttings, and division, according to the American Begonia Society. You can save time and effort by employing these strategies if you already have mature begonias in your garden. If you start with begonia propagation in a greenhouse, you may find it easier due to the more stable and controlled environment.

Stem cuttings

Begonias can be grown in both water and soil. When it comes to stem cuttings, they are one of the easiest plants to propagate, regardless of your level of skill. To avoid stressing your cuttings source, begin by taking cuttings from a healthy parent plant.

Sections under a node of about 4 inches in length should be cut, but only if they are disease- and damage-free. This is also a great time to revive your leggy begonias so that they can continue to supply you with cuttings in the coming year. Use a sterilized and sharp tool to make a precise cut.

Preparation for rooting begins with the removal of lower leaves that may decay in water or soil. If you remove all the blossoms from the cutting, you’ll be able to divert the cutting’s energy toward root growth. In order for the cuttings to take root, place them in a pot of water or a glass of water.

Leaf cuttings

Begonias can be rooted from leaf cuttings as well as stems. Look for a mature, robust leaf with thick main veins, but don’t be alarmed if the underside appears to be a little frayed. Remove the stem from the leaf before cutting it in half.

To see where the begonia leaf will generate plantlets, flip the leaf over and use a sharp and sterile knife to make a half-inch cut across the biggest veins. Cut the veins one inch from the principal vein if you’re one of those gardeners. Afterwards, flip the leaf over and push it into your medium..

When pinning down the leaf, be careful not to harm any of the veins in the leaf. Cover the container with plastic and keep the soil moist to encourage root growth. For faster growth, you can also put them in a greenhouse with fluorescent lights.


Finally, if you have older begonias, you can divide them to propagate and maintain them. Your plants will produce fewer flowers as they mature and produce larger tubers that are suitable for division. Begonias should be divided as soon as the buds have puffed up for best growth.

Remove the plant from the ground by digging around it, and then divide the tubers into parts. In order to speed up the flowering process, ensure each division has at least one bud and is large enough. To avoid illness, allow the tubers to dry completely before planting and use a fungicide on them.

To facilitate growth, place the divisions in a pot with the shoots sticking out. If you want to keep the chopped portions free of fungus, make sure they’re buried deeply. Until they are ready to be transplanted, you can keep the divisions in the greenhouse.

How to Retrieve Seed From Begonia Plant

Begonias can be grown both indoors and outdoors. It is common for people to cultivate the plants for their lovely foliage or brightly colored blossoms. There are no USDA hardiness zones in which you cannot grow begonias as an annual or grow them indoors. They are usually planted in pots or hanging baskets in regions with filtered sunlight. There are both male and female flowers on the same plant, but the female flowers contain a seed capsule attached to them.

Observe for seedpods after the begonia flowers have dried and shrunk in size. Feminine flowers have a large ovary at the base of the bloom and do not have yellow stamens, which means the seedpods are hidden behind them.

If you notice that the seedpods are beginning to dry out, remove them from the plant, but don’t harvest the seedpods until they’ve fully dried out and split open, releasing seeds.

A piece of white paper, such as typing paper, can be used to open the seedpods. Empty them.

4. Store deeds in an empty pill bottle or other small plastic container until they are completely dry. You can funnel the seeds into the container by folding up the white paper and inserting it into the opening. For the seeds to dry, it usually takes a week or so, although this can vary.

5.Pour the dried seeds onto a piece of white paper, such as a typing pad. Gently slide the seed and chaff-filled paper over the second sheet of white paper using the second sheet. The chaff will fall to the ground, leaving behind only the seeds. If no seeds fall to the ground, it could be chaff, not viable seeds.

Seeds should be poured into an envelope and taped shut with a date on it so that you know what type of seed it contains.


Begonias can be grown by cuttings of stems, leaves, or division. However, if you know how to collect begonia seeds and how to use faded blossoms after the flowering season, you can get the most out of your plants. Gather the seed pods, dry them, remove the straw, and store them in an airtight envelope.


Begonia seeds should be started indoors in January so that they will blossom and be large enough to be transplanted to the garden in the spring. They should be started in January.


Begonia is a prolific crossbreeder. To ensure that the seeds you gather are true to the parent, you must either hand pollinate or collect seed from single-variety beds.
