Propagation of Bougainvillea – When, How, and Where

Do you enjoy bringing color to your landscape with gorgeous plants that offer a range of blooms and fragrant scents? Then bougainvillea is the finest choice, as it provides the garden a stunning aspect and offers the visitor a sense of freshness. Flowers in bloom have a lovely scent and come in a range of hues.

The Bougainvillea plant requires special care because it is a difficult plant to cultivate. Bougainvillea need 4-5 hours of direct sunshine to blossom. The right amount of water vapor from the environment keeps the plant alive and well.

So, how do you cultivate bougainvillea properly? Bougainvillea comes in two varieties: seeds and cuttings. Here is a step-by-step guide on how to propagate a bougainvillea plant.

Propagating Bougainvillea

Cutting and sowing are two basic strategies for propagating bougainvillea. Cuttings are the most typical method of propagation for this plant. Seeding is a technique that is less regularly utilized.

Bougainvillea Propagation via Cutting

The majority of bougainvillea propagation is done by cutting the mature stem. The steps in a proper propagation process are as follows.


Cut a mature stem from the plant with a length of at least 6-8 inches. Pruning shears must be sharp for the greatest cutting results. Cuttings must be clean, healthy, and devoid of illnesses and diseases. Correct stem cutting enhances the surface area of the stem, allowing it to absorb nutrients and water vapors from the soil.

Because the roots of this plant are vulnerable, you may fail on your first attempt. Prefer the woody section of the stem for optimal results, and take the cuttings with care. The juvenile regions of the stem, especially the greenish area, should be avoided. A plant’s healthy production depends on the presence of seven nodes on its stem.

Must Cut Leaves

The leaves must be clipped off the stem to reach the root exactly for a satisfactory result. The stem must be stripped of all leaves, flowers, and other side branches. Remove all of the green parts so that the woody section is the most visible. The greenish portion does not produce beneficial outcomes and has a lower chance of survival.

Bougainvillea leaves

The absence of leaves permits the stem to absorb all of the necessary moisture from the soil. Fine root development necessitates and benefits from nutrition and hydration. Keeping the cuttings fresh and preventing them from drying can be achieved by placing them in a plastic bag and storing them in the refrigerator.

Rooting Hormone

Put the bottom of the stem in the rooting hormone powder to increase the quantity of roots. The coating should be done correctly to avoid a mess. If there is too much clumping, lightly tap the stem.

Plant nurseries, gardening shops, and greenhouses sell rooting hormone (rooting acid). Rooting acids are the greatest for growing healthy roots since they minimize dryness and keep the roots from dying. The ingredients that may be used to make rooting hormones at home include honey, apple cider vinegar, cinnamon, and crushed aspirin.


Take a small container with well-drained soil that has enough oxygen and moisture for the roots to absorb. The pot should have a medium-sized design to ensure that cutting propagation yields the greatest results. A 14-inch gap should be allowed between the top pot and the water entry.

When utilizing garden soil, choose a porous material to allow water to drain properly. The pot should be the right size for the roots to develop properly. Because the roots are delicate and easily broken, they require special attention.


The cutting should be inserted such that it does not break and is correctly seated. If the soil is too thick, create a hole first and then insert the cutting stem. The stem will not be damaged or broken as a result of this. The angle at which the nodes are inserted should be such that they germinate into the roots.

Adding Water to the Plant

Proper plant watering will saturate the soil’s surface, allowing the plant to absorb more nutrients. Healthy water intake will allow the roots to grow properly and give the plant with a healthy root system.

Too much water will damage the roots, limiting the plant’s ability to develop. Fungal and other root infections are harmed by excessive wetness. In comparison to flowers, the development of leaves will be more noticeable.

Covering The Pod

Covering the pod creates a greenhouse effect, which helps the plant retain moisture and humidity. Plants will grow quickly if there is enough of water. Keep the pot cool and at a low temperature by avoiding direct sunshine. The plastic bag should be firmly secured, sealing the pot’s bottom.


The cutting must sprout and undergo the growth of new plant components for 6-10 weeks. When new leaves appear on the stalk, the plant begins to expand. Remove the bag during the sprouting process to prevent disturbing the plant. Plant growth may be slowed as a result of this. It is preferable to wait for the plant’s natural development until it has fully branching.

Method of Seed Propagation

It’s difficult to get the right seeds for bougainvillea multiplication. Plants that are well-established and yield the appropriate seeds are required. Look for leaves with additional brilliant blooms around them. Allow the bract to dry before ripening, which should take around a month. The seed is contained in three pods inside the bract.

Bougainvillea seeds

The seeds should be brown in color and spherical in shape. The seed should be carefully extracted from the pods. Fresh seeds are simpler to extract from pods than seeds that have been more tightly encased.

For seed propagation, the soil has to be well-drained. From the top, the container should not be too thin. The container should be kept in a location that allows it to get adequate sunshine. The seed must be able to withstand the heat, which necessitates adequate container modification.

Bougainvillea seeds should be strewn on the soil’s surface but not too deeply. Water the seeds and patiently wait for them to sprout, since this takes a long time. However, it produces commendable outcomes.

When should Bougainvillea be propagated?

From late spring until mid-summer, the Bougainvillea plant grows at its fastest and most plentiful. The bud nodes expand at this period, giving rise to the branches, leaves, buds, and flowers.

Bougainvillea Growth

Bougainvillea grows to be 20-30 feet tall and has a wide range of colors. This plant stands 11-12 inches tall and is 8-10 feet broad. Dwarf sizes, which are 3-6 feet broad and tall, are also available.

Bougainvillea propagation and transplanting

The majority of root damage happens when the bougainvillea plant is transplanted. Water the plant thoroughly to avoid root damage. Transplanting should take place in a location that receives adequate sunlight. The steps for transplanting Bougainvillea are as follows.

Leaves’ Appearance

The clipped stem should be continued to be rooted until leaves appear. Depending on the soil conditions and the stem cutting, this procedure might take several months (3-6). You may safely transplant the stem into the garden or into a container after the green leaves grow.

Exposure to the Sun

The roots cut stem has to be in direct sunshine. Most gardeners advocate this since the plant becomes used to the new surroundings. The plant adapts to the shift in the environment during this period, which lasts at least two weeks. Direct sunshine exposure will assist the plant in acclimating and ensuring optimal development.

Temperature Control

You must maintain the temperature of the transplanted stem throughout this period. Bring the pot inside during the hottest part of the day (afternoon), then return it after nightfall. Because young cuttings are fragile, abrupt temperature fluctuations are not safe for the plant. Room temperature is the optimal temperature for bougainvillea since it fits them best at human temperature.


The plant is now prepared to take root in the garden. The roots should be gradually pushed out of the compacted dirt. Take care to hold the pot in one hand while holding the cuttings in the other. The plant is now ready to develop on its own and should be put in a garden.

Bougainvillea Growing Conditions

The following are the requirements for growing a bougainvillea plant:

The plant creates a range of hues when exposed to 6-8 hours of sunshine.

For a healthy plant, well-drained soil is needed.

The ability to regulate temperature is critical to the plant’s existence.

Fertilizers such as nitrogen, phosphorous, and potassium will encourage a robust plant with a lot of blooms.

Fine wires are used to train the plant to climb a wall or frame doors, and the plant is directed in the appropriate direction to spread and offer a lovely appearance.

Bougainvillea Propagation Season

Late spring to mid-summer is the optimal time to propagate Bougainvillea. Because the stem loses its green leaves in the winter, it is not a good season to propagate bougainvillea. The optimal time to harvest plants is in the spring and mid-summer, when plant development is at its peak.


Can bougainvillea be grown from a cutting?

Cuttings are the simplest way to cultivate bougainvillea. That is something you can do at any moment of the year. The cutting should be immersed in rooting acid to encourage good development. For multiplication, the leaves should be detached from the stem and solely inserted into the woody section of the soil.

What fertilizer is best for bougainvillea?

Nitrogen (N), phosphorus (P), and potassium (K) are the finest fertilizers for bougainvillea plants (K). The fertilizer should be used in a proportional amount. Fertilizers, particularly nitrogen fertilizer, produce the best outcomes and flower development.

Is it possible to cultivate bougainvillea in the shade?

For the finest bloom, Bougainvillea need plenty of sunshine. They do, however, grow well in the minimal shade. The leaves will grow in profusion, and blossoming will require adequate sunshine (6-8) hours.


Colors should be added to your garden to make it more vibrant and appealing. Plants that cover your walls with newly blooming flowers and pleasant scents create a wonderful atmosphere. Get a bougainvillea plant for an unforgettable experience and a stunning appearance where the lovely scent of blossoms will rejuvenate your spirit.
