How to Care for Bougainvillea in Autumn
Do you know these? Here's an introduction to the care of bougainvillea in autumn and techniques for reblooming in the fall season. Below, the editor provides a detailed explanation for you.
Autumn is also the blooming season for bougainvillea. Many varieties that bloom frequently can bloom multiple times a year, especially in spring and autumn, with a higher number of blooms. As the weather cools down in autumn, many gardening enthusiasts find that their bougainvillea starts to grow flower buds again at the tips of the branches, and it won't be long before they are full of blooms once again. So how can we make bougainvillea rebloom in autumn? Just focus on four things, and it will bloom again soon.
Remove Messy Branches
The reason why many bougainvillea plants fail to bloom in autumn is that the branches grow too lush, consuming a large amount of nutrients from the plant, leaving no extra nutrients for growing flower buds.
If the bougainvillea in your home has grown too lush, you should prune it, removing the weak branches and cutting back the tall and long ones. For dense foliage, some leaves should be removed to increase ventilation and light between the branches while also reducing nutrient consumption.
After pruning, the bougainvillea will quickly sprout new branches with the help of water and fertilizer. Once new branches grow, you can proceed to encourage blooming.
Water Properly
Bougainvillea is drought-tolerant, but proper watering is essential at different growth stages to ensure vigorous growth and more flower bud formation.
In autumn care, recently pruned bougainvillea needs ample water to promote the growth of new branches. The potting soil should not be too dry and should be watered thoroughly when it starts to dry out.
Once new branches sprout, you should control the watering to encourage blooming. If you continue to water excessively, the plant will keep growing leaves and not form flower buds. After new branches have grown, allow the potting soil to dry a bit between waterings. Only water when the leaves start to wilt slightly, which will give the plant a sense of crisis and prompt it to grow flower buds quickly.
How to Care for Bougainvillea in Autumn
Apply Phosphorus and Potassium Fertilizer to Encourage Blooming
Bougainvillea should be fertilized and supplemented with nutrients in autumn, especially after pruning. It's important to water the plant with dilute fertilizer or apply a compound fertilizer to ensure ample nutrients for the plant to grow new branches and make them stronger, laying a good foundation for blooming.
After new branches grow, use phosphorus and potassium fertilizer to encourage blooming. Apply monopotassium phosphate or Flower多多 No.2 fertilizer once a week, dilute it at a ratio of 1:1000, and pour it directly into the flower pot, or spray it on the branches and leaves. Continuous use for three times will help the plant form flower buds on the new growth.
Ensure Sufficient Light
Bougainvillea, a plant that loves sunlight, cannot grow without adequate light. Insufficient light can lead to plants growing weak branches that are not prone to flowering and consume a lot of nutrients.
When caring for bougainvillea in autumn, there's no need to worry about sunburn. Place it in a sunny location to ensure that the new branches are strong, and as soon as they grow, they can immediately start growing flower buds.
Now is the peak growing season for bougainvillea. If a plant only grows leaves and not flowers, you can prune some branches, then encourage it to grow flowering branches by adding phosphorus and potassium fertilizer and increasing light exposure. After some time, the plant will form flower buds on the new branches.
