The lovely heliconia and their exotic blossoms give the South Florida landscape a lush, tropical appearance. These plants feature thick, robust stems wrapped in big, banana-like leaves. The flower stems develop vivid erect or pendulous flower clusters that closely resemble birds of paradise plants from highly colorful waxy leaves. The peculiar blossoms resemble those of the bird of paradise, and orange versions of this plant are frequently mistaken for orange birds at first glance because of this. Flowers bloom during the warm months of the year and range in color from orange to red to yellow. These plants might not be the best option for every yard.
How to Grow Indoor Heliconia
Sunlight
Give indoor plants the greatest possible indirect light when growing them. Heliconias require a lot of warmth and light to produce blossoms; the optimal environment is a heated greenhouse or sunroom. Otherwise, pick a window that faces the south or west and turn it occasionally to ensure that the entire plant receives light.
Artificial Light
If the plant does not receive up to eight hours of sunlight each day, you will need to supplement with artificial fluorescent grow lights, especially if you encounter shorter days in the winter.
Temperature and Humidity
Since heliconia plants are indigenous to tropical jungles, they favour warm, humid weather. Ideal temperatures are 70 degrees Fahrenheit or above. Indoor plants in northern areas will need frequent spraying to prevent the leaves from drying out during the dry winter months. The leaves’ brown tips and margins are a warning that the plants require moisture air. Additionally, at least once a week, dampen a towel and wipe away any dust that has gathered on the plant’s leaves.
Watering
All Heliconia species need plenty of water that flows continuously to flourish, but they also need proper drainage. The most important factor in successfully cultivating these plants is proper hydration. Drought-affected plants will develop leaf browning, particularly at the leaf margins. Use lukewarm water while watering your plant to protect it over the winter. Make sure the soil is almost completely dry before watering, and then do it right away.
Air Circulation
Because this water-loving plant is prone to fungus growth, it’s crucial to ensure that there is air movement around it to avoid humid circumstances. To prevent foliage from falling to the ground or covering the pot, use stakes. Separate plants that are crowded since it can trap moisture. For better ventilation, this plant might benefit from a ceiling fan or oscillating fan.
Fertilizer
Throughout the growing season, fertilize every two weeks with a mild liquid fertilizer. In the winter, reduce fertilizer application to once a month or less. You need a fertilizer with a higher phosphorus level for flowering. For phosphorus supplementation, use a bone meal product. It can also make root systems stronger.
Pruning and Maintenance
As they wither, cut off the spent blooms and stems. You should cut back the old flowering stalks as soon as new ones emerge from the earth.
Potting Soil and Drainage
Potted plants benefit from a rich, peat-based potting soil with adequate drainage. In excessively damp soil, these plants can develop root rot very quickly. The best potting soil is a uniform blend of peat moss and wood-based compost.
Potting and Repotting Heliconia
Heliconia rhizomes are best potted in the early spring before the growing season starts. These plants don’t require frequent repotting despite their rapid growth. They do not mind being slightly pot-bound, and a smaller pot may help them grow more effectively. Adult plants should be divided to grow your collection and keep it manageable because plants clump over time. Rhizome division is the simplest method for growing these plants. A tuberous root called a rhizome can be taken out and replanted to create new plants. Divide the rhizome (with at least two developing nodules) at the time of repotting and plant each portion individually. Approximately six months after the rhizomes are planted; smaller types will begin to bloom.
