Why isn't my bougainvillea flowering as autumn arrives?
Here are some small experiences on the maintenance of green plants for the situation where the bougainvillea doesn't flower even after autumn arrives:
What should I do if my bougainvillea still doesn't flower and just grows branches in autumn? Don't worry, just four simple steps can make the bougainvillea burst into bloom throughout autumn and winter.
Bougainvillea Flowering Tips for Autumn
If you want your bougainvillea to flower more frequently and abundantly, you should focus on two more and one less during maintenance: more sun exposure, more fertilizing, and less watering. If your bougainvillea is still flowering very little or not at all, you are advised to promote flowering by following these four points.
1. - - More Sun Exposure - -
Bougainvillea is a sun-loving plant that thrives in direct sunlight. When maintaining, ensure it gets plenty of light, especially after autumn when the intensity of sunlight weakens. Place it in a well-lit position to receive full sun. Only with sufficient light can the bougainvillea bloom densely.
2. - - Moderate Pruning - -
For bougainvillea with excessively long branches, pruning should be done promptly in autumn to shorten the long branches. Very thin and weak branches should also be cut. Moderate pruning can inhibit the excessive growth of bougainvillea branches, promoting more lateral branching and flowering.
Of course, if you want to create a flowing shape, long branches can be retained according to need and pruned into the desired shape. Bougainvillea is very resistant to pruning and can quickly sprout new buds even when剪秃, so don't worry about killing it.
3. - - Supplement Phosphorus and Potassium Fertilizer - -
Pruning is to give the bougainvillea a better shape during flowering in autumn and winter. If you want the bougainvillea to flower abundantly and for a long period, you must ensure sufficient phosphorus and potassium fertilizer. After pruning, it is recommended to shallowly bury an appropriate amount of bone meal fertilizer at the edge of the pot. For a 2-3-gallon pot, you can shallowly bury about 100g of bone meal.
Bone meal is a natural phosphorus and potassium fertilizer that can continuously provide nutrients to the bougainvillea, promoting more flower leaves and extending the blooming period.
4. - - Water Control for Flowering - -
The growth habit of bougainvillea is special; it tends to flower more easily in a relatively dry environment. Therefore, to make the bougainvillea bloom earlier, it is usually necessary to control watering, which we call water control.
Water control needs to be moderate. It is recommended that you water when the leaves of the bougainvillea become soft and droopy or when the tips of the young branches become soft and droopy, making the bougainvillea feel the threat of drought. Water after the leaves become soft, adding monopotassium phosphate fertilizer to the water.
Usually, after a month of continuous water control, you can see the bougainvillea produce flower leaves. When the bougainvillea produces flower leaves, stop water control, keep the soil dry and water thoroughly, and add a little monopotassium phosphate fertilizer with each watering.
By persistently watering with fertilizer, the bougainvillea will quickly burst into bloom, and the flowering period can last until winter. Keeping the plant warm in winter and protecting the branches will allow it to bloom again in spring.
Is the above introduction on flowering promotion techniques for bougainvillea in autumn and the situation where the bougainvillea doesn't flower even after autumn clear to you?
