The Colorful Mystery of Bougainvilleas
Bougainvilleas are beautiful plants that can add a splash of color to any garden. But sometimes, these plants can surprise us by changing color. Why does this happen, and can we do anything about it?
About Bougainvillea Colors
The vibrant colors we see on bougainvilleas are not actually petals, but bracts. Bracts are leaf-like structures that protect the true flowers, which are tucked inside. Bougainvillea bracts come in a wide range of colors, including pink, red, purple, yellow, and white.
Why Did My Bougainvillea Change Colors?
There are several reasons why your bougainvillea might have changed color. Unfortunately, it’s not always possible to pinpoint the exact cause.
- Cross-breeding: If your bougainvillea is a different color from when you bought it from a nursery, it may be a result of cross-breeding. Bougainvilleas are often cross-bred to create new varieties with different colors and patterns.
- Environmental conditions: The conditions in your yard can also affect the color of your bougainvillea. Differences in temperature, soil type, alkalinity, light exposure, and water can all cause color changes. For example, bougainvilleas grown in pots may have different colors than those grown in the ground.
- Nutrient deficiencies: Bougainvilleas need certain nutrients to produce healthy bracts. If your plant is not getting enough of these nutrients, it may start to change color.
Can I Change the Color of My Bougainvillea?
It’s not always possible to change the color of a bougainvillea back to its original color. However, you can try changing the conditions to see if it triggers a shift in color.
- Provide the right growing conditions: Bougainvilleas prefer slightly acidic soil that is moist but drains well, indirect light, and warm temperatures. If your plant is not getting these conditions, it may be more likely to change color.
- Fertilize regularly: Bougainvilleas need regular fertilization to produce healthy bracts. Use a fertilizer that is specifically designed for acid-loving plants.
- Water regularly: Bougainvilleas need regular watering, especially during hot weather. Allow the soil to dry out slightly between waterings, but don’t let it get too dry.
- Repot if necessary: If your bougainvillea is growing in a pot, it may need to be repotted into a larger pot as it grows. This will give the plant more room to grow and access to more nutrients.
How to Maintain the Color of Your Bougainvillea
If you’re happy with the color of your bougainvillea, there are a few things you can do to maintain it:
- Keep the plant in a stable environment: Avoid making sudden changes to the plant’s growing conditions, such as moving it from full sun to full shade.
- Water regularly: Bougainvilleas need regular watering, especially during hot weather. Allow the soil to dry out slightly between waterings, but don’t let it get too dry.
- Fertilize regularly: Bougainvilleas need regular fertilization to produce healthy bracts. Use a fertilizer that is specifically designed for acid-loving plants.
By following these tips, you can help your bougainvillea maintain its beautiful color for years to come.
