Propagation of Bouvardia

Most Bouvardia varieties can be propagated in three different ways. You can either chose-

  1. Seeds.
  2. Stem Cuttings.
  3. Root Cutting.

Bouvardia seeds are very tiny hard to collect. These seeds are rare to find on Amazon or at any seed store. Still, it is the most common natural way of propagating the Humminbird flower. Similarly, the root of the Firecracker bush or Bouvardia contains nodes that can grow into new plants.

Commercial gardeners always use root cutting as they grow faster and healthier than other means. These are also easier to find, collect and grow.

Finally, we have the stem cutting. Bouvardia can also be grown with healthy stem cutting. It is an effective way to propagate Bouvardia although this is not a natural technique. This requires manual effort with specific tools and rooting hormones to form roots.

Preparation to grow Bouvardia

  1. Select Container or pot for Indoor gardening. Start with a 6-inch pot with a proper drainage hole in its bottom. Choose a well-lit outdoor garden area to grow Bouvardia. The garden spot must have a minimum of 2×2 feet area open and clear for the new Bouvardia plant.
  2. Prepare Soil mix for rooting in Bouvardia Cuttings. Use 50% sand and 40% garden soil with 10% Cocopeat or peat moss for rooting. Use compost instead of cocopeat in a cool climate.
  3. Prepare Soil mix for First Transplant: Use 30% garden Soil, 30% sand, 30% compost with 10% Cocopeat. This soil mix is sufficient to support Bouvardia for the first growing year. From the next year mix 60% Soil with 40% organic compost to grow Bouvardia.
  4. Dig holes in the garden a couple of days before plantation. In fact, you must sundry the soil and let the holes dry and aerate for the best result. Also, dry out the pots and containers in full sun to avoid fungal spore growth.

How to Grow Bouvardia Plants?

Grow Bouvardia with seeds

  • Bouvardia seeds are hard to find although if you find some then start with drying them in full sun for two days.
  • Then use a seedling tray at least 4 inches deep. Fill it with sand, soil, and compost in equal proportion. Then sprinkle the seeds evenly over the soil surface.
  • Sprinkle some soil mix over the seeds to keep them in position. Don’t overdo this. Heavy soil can slow down or completely stop germination.
  • Spray water over the seedling tray carefully. Use a fine spray nozzle and avoid any disturbance to the seeds. Never use a tumbler or mug else the water will flood the tray. It will wash off the seeds from their position.
  • Cover the seedling tray with transparent plastic wrap.
  • Put the container near a window where it can receive some sunlight.
  • Open the covering once or twice every week for aeration and watering. Always keep the soil moist and warm.
  • The Bouvardia seeds may take 6 to 8 weeks to germinate. So be patient and take care of the seedling tray.
  • Keep in mind plants grown from seeds can vary a lot from their parent Bouvardia plant.

Grow Bouvardia with Root Cutting

  • Take a thick mature Bouvardia root for this purpose. It should have 4 or 5 nodes in it.
  • Cut out the nodes in 2 to 3-inch pieces. Try to keep the nodes in the center of both cuttings. You can also germinate the entire root and separate the baby plants later.
  • Put the Root cutting in a Sand soil mix. Water the mixture and place the cuttings in it. Cover the roots with 1/2 inch of the same soil mix.
  • Again spray some water and cover it to maintain warmth. Try to keep the temperature around 70 degrees Fahrenheit.
  • These Bouvardia roots will germinate within 3-5 weeks. Meanwhile, keep the soil mix warm and moist.

Grow Bouvardia with Stem Cutting

  • Take 4-6 inch stem cuttings from a healthy Bouvardia plant. The stems must be clean and free from any disease. Otherwise, the disease can damage your new plant batch.
  • Remove some of the lower leaves from the cuttings.
  • Dip the lower end of the cutting in rooting hormone powder.
  • Take equal parts of sand, soil, and compost in a seedling tray.
  • Level the soil mix and water the soil to increase moisture.
  • Make some holes in the soil mix and put the stem cutting in these holes. Tap the soil to settle down the stems.
  • Cover the Soil and stem with plastic wrap to create a microenvironment. The wrap will act as a greenhouse and increase the temperature up to 80 or 90 degrees Fahrenheit.
  • Open the wrap once in 3 days for aeration and always keep the soil moist.
  • The Bouvardia stem cuttings will develop roots in 6 to 8 weeks. The plant thus grown are identical to the parent plant.

Transplanting Bouvardia Plants

Bouvardia plants must be transplanted to 5 or 6-inch containers for the first 2 years. Retransplant them once every year to encourage stronger root growth.

  • Take out the plant from the pot with the root ball intact.
  • Cut off dead roots and extra branches. Also, remove the extra unwanted root systems without damaging the central root.
  • Replace the groomed Bouvardia plant back in the container with some compost.
  • Transplant the Bouvardia into a bigger 10-inch pot or container or in the garden after 3 years.
  • Once the Plant is fully mature and continues flowering the whole season, simply stop uprooting it. Instead, dig out 3 or 4 inches of the topsoil and fill the space with compost and fresh soil. Water thoroughly and leave the plant undisturbed for the next 8 to 10 months.

The easiest way to Propagate Bouvardia

The easiest way to propagate Bouvardia is by root separation. The mature roots will naturally develop lots of baby firecracker bushes. Once they are bigger than 3 or 4 inches, you can dig them out.

Use a sharp spade or just a knife to detach the roots from the parent plant. Take the baby plant out and away from the parent plant and grow it wherever you want. This is the easiest and most convenient way to propagate Bouvardia if you already have a mature plant.
