Why isn't the bougainvillea blooming as autumn sets in?
Article Summary: This is an introduction to the bougainvillea that fails to bloom as autumn arrives, a green plant and flower aspect worth exploring.
Bougainvillea, also known as paperflower, has a variety of colors and a long blooming period, making it beloved by many gardening enthusiasts. However, many also find it disappointing, as it often doesn't bloom even after prolonged care, not living up to its reputation of continuous blooming, making it seem like one is nurturing a fake bougainvillea.
Blooming Period of Bougainvillea: The blooming period of bougainvillea is incredibly long, lasting from May and June in spring to winter. The reason many gardening enthusiasts' bougainvilleas don't bloom is often related to the variety of the plant. Some bougainvilleas are lazy bloomers, flowering only once in autumn or even just a few flowers.
Therefore, choosing the right variety of bougainvillea is important. Opting for more diligent bloomers makes it easier to achieve a full pot.
Reasons for Non-Blooming Bougainvillea
Bougainvillea not flowering is related to many factors, such as light, temperature, pruning, and fertilization and watering.
1. Insufficient Light: Bougainvillea requires ample light. If the environment where it is cared for has insufficient light, it rarely blooms.
2. Improper Pruning
Bougainvillea has a vine-like nature, so to encourage more blooms, frequent pruning is necessary. If not pruned, the bougainvillea will continuously produce branches, which will grow long without many flowers.
Therefore, it is essential to剪 back the overly long branches to suppress their growth.
3. Inadequate Fertilization and Watering
Bougainvillea is highly tolerant of poor soil, so many gardening enthusiasts tend to neglect it. However, severe nutrient deficiencies can affect the normal blooming of bougainvillea, so fertilization and watering should still be maintained.
What to do if the bougainvillea still doesn't have flower buds in autumn? If your bougainvillea still shows no signs of blooming at this point in the season, here are two tips to promote blooming quickly.
1. Pruning Vigorous Bougainvillea Branches
For very vigorous bougainvillea with long branches, the first step is to prune the branches, cutting off 1/2 to 2/3 of their length.
After pruning, remove the large leaves from the remaining branches, leaving the bougainvillea almost bare. Then, apply a dose of fermented chicken manure and follow up with a phosphorus and potassium fertilizer every 7 days.
This treatment usually results in visible flower buds in about 10 days.
2. Bougainvillea Without Excessive Growth
If the bougainvillea is not growing robustly and doesn't have a strong growth habit, it may be due to insufficient fertilization and watering. For such plants, there's no need to prune; simply apply phosphorus and potassium fertilizer.
Remove most of the large leaves from the branches to stimulate growth and blooming. This treatment also usually results in flower buds in about 10 days.
Note: Regardless of the method used to promote blooming, it is necessary to ensure there is sufficient light, preferably full sunlight.
The above information regarding the non-blooming of bougainvillea in autumn is hoped to be of help to you!
