Reasons Why Bougainvillea Does Not Bloom and Key Care Tips

  Recently, many flower lovers left messages saying that the bougainvillea they have grown for a long time is only wildly growing leaves, but no matter what, they cannot see it bloom, which is really a headache. The editor has sorted out some reasons why bougainvillea does not bloom. Flower lovers, take a look and see whether you have fallen into these traps.

  Is the temperature too low 

  Bougainvillea itself is a flower that grows in the south and loves a warm and humid environment. If a friend in the north keeps a pot of bougainvillea at home, attention must be paid to temperature control. Generally, only when the temperature is kept above 18°C will bougainvillea bloom. Otherwise, when bougainvillea is forming flower buds, it will be affected, causing the flower buds to fail to form, or the flowers to wither quickly when they bloom. In summer, if the temperature is too high, pay attention to cooling and increasing humidity.

  Prune when it is time to prune, do not hold back 

  The branches and leaves of bougainvillea generally grow quite vigorously, which easily competes with the flowers for nutrients, causing bougainvillea to grow only leaves and not bloom. So, for bougainvillea, it is better to prune the branches and leaves often. If bougainvillea is not pruned for a long time, it will grow very tall, so in its early growth stage, it must be pinched and topped to prevent it from growing straight upward. For branches and leaves that are too long, they should be cut shorter. If the branches grow too densely, they should be thinned out to promote ventilation and air circulation.

  Water when the potting soil is dry, moist is enough 

  When you see that the potting soil of the bougainvillea has become somewhat dry, you can water it a little. Once it looks moist, do not water it again. Before bougainvillea blooms, reduce the frequency of watering, as this helps bougainvillea form flower buds.

  Sufficient light and good ventilation conditions 

  Bougainvillea is a light-loving plant, and sufficient light has a great effect on the opening of bougainvillea flowers. The more sufficient the light, the more vigorously the bougainvillea blooms. If your bougainvillea has always been kept indoors and cannot receive sufficient light for a long time, it is only natural that it cannot bloom. Bougainvillea needs about 8 hours of light per day. Do not worry, it will not be scorched to death. Except for seedlings, bougainvillea at other growth stages is best kept outdoors, so that there is sufficient light and good ventilation conditions.

  Fertilizer amount is not controlled properly 

  As we mentioned earlier, the branches and leaves of bougainvillea should not be allowed to grow too vigorously, so the amount of fertilizer must be well controlled. Generally, before flowering, nitrogen fertilizer should be limited and phosphorus fertilizer added, as this can promote the opening of bougainvillea flowers.

  Summary of key points for bougainvillea care: 

  1. Light must be sufficient

  2. Water and fertilizer management should be strengthened

  3. Moderate pruning is very necessary

  The above are some key points on bougainvillea care compiled by the editor. Flower lovers, do you now understand where you went wrong?

      Green leaves set off bright red bracts, like a peacock spreading its tail, especially dazzling and eye-catching. This is bougainvillea. In its hometown of Brazil, women often wear it in their hair as decoration, which is quite unique. Today the editor will briefly introduce how to grow bougainvillea and let everyone enjoy bougainvillea pictures.

      Bougainvillea picture appreciation. First, the editor will introduce cultivation in the methods of growing bougainvillea. Bougainvillea cuttings first sprout buds and grow branches, then take root. Therefore, when the branches sprout buds and grow leaves, they must not be transplanted or the soil loosened, so as not to affect root formation on the branches.

       Bougainvillea likes high temperatures and sufficient sunlight. As long as the soil remains moist, it is not afraid of exposure to the sun. When autumn arrives that year, it should be intentionally kept in the pot for one month, that is, after its branches and leaves are lush, water less and keep it half dry and half wet, so that its green leaves fall and flower buds grow strongly. "Picking leaves can sprout buds, controlling water can grow flowers" - this is the unique character of bougainvillea.

      Bougainvillea picture appreciation. What about the methods of growing bougainvillea? Bougainvillea grows quickly, and during the growth period attention should be paid to shaping and pruning to promote side branch growth and produce more flowering branches. The number of prunings is generally 1 to 3 times, and it should not be too many, otherwise it will affect the number of times it blooms.

       After each flowering, remove spent flowers in time to reduce nutrient consumption. After the flowering period, thin out overly dense branches, inner branches, leggy branches, and weak branches. For other branches, generally do not prune, or only trim the tips slightly. Do not prune heavily, so as to shorten the next growth period and encourage earlier and repeated flowering.

      Bougainvillea picture appreciation. In the methods of growing bougainvillea, watering and fertilizing are very important. So how should watering be done?.
Watering
      In the early summer growth season, water once a day to ensure branch and leaf growth. From June to July, according to different varieties, control water appropriately 3 to 4 times. The degree of water control is to make branch tips and leaves slightly wilt. After being brought indoors in winter, keep to not watering when not dry, and water thoroughly when watering.

Fertilizing
      Bougainvillea blooms a lot and has a long flowering period, consuming many nutrients. In addition, the potting soil is limited, so fertilizer must be supplemented regularly. When repotting in spring, apply sufficient base fertilizer. During the vigorous growth period, apply decomposed cake fertilizer water every 7 days to accelerate flower bud differentiation. When flower buds appear in the leaf axils, more fertilizer and heavier fertilizer can be applied, mainly phosphorus and potassium fertilizer.

      Bougainvillea picture appreciation. After introducing the methods of growing bougainvillea, let's understand why bougainvillea does not bloom.
      1. Bougainvillea is native to tropical regions and likes strong light. Throughout its growth period, it needs sufficient light. The longer the sunshine duration, the more it blooms and the more brilliant the flower color. Conversely, if bougainvillea cannot get sunlight for a long time, not only will it not bloom, but the color of the leaves will gradually become lighter and may even fall off.
      2. Whether bougainvillea blooms is also related to the size of the flower pot. Bougainvillea has a well-developed root system. Planted in the open air, its roots can extend several meters, so the flower pot should be replaced often according to the size of the plant.
      3. The last and most important point is water control and fertilizer control. Before the bougainvillea flowering period arrives, control the amount of watering, and water appropriately only when the leaves are slightly wilted. Stop applying nitrogen fertilizer and increase phosphorus and potassium fertilizer.

      Bougainvillea has high ornamental value. In southern China it is used as a climbing flower cultivated on walls, while in the north it is used as a potted flower mainly for viewing flowers in winter. Today the editor's introduction to the methods of growing bougainvillea and why it does not bloom ends here. Thank you all for reading.

How to plant bougainvillea. Why bougainvillea does not bloom

Bougainvillea is the national flower of Zambia and the city flower of many cities around the world. What is the method of planting bougainvillea? Why does bougainvillea not bloom? Let's look at the answers below.

How to plant bougainvillea

First, water scientifically, combining watering, water control, and heavy watering. During the growth season of bougainvillea, water once a day to ensure the growth of branches and leaves. From June to July, control water appropriately to make branch tips and leaves slightly wilt. This helps flower bud differentiation. When new shoots show flower buds, water heavily once in the morning and once in the evening each day, and spray the leaves with water 1 to 2 times. When the temperature is low in winter, appropriately reduce the frequency of watering.

Second, fertilize properly. Bougainvillea consumes many nutrients during flowering, so fertilizer should be supplemented appropriately. When repotting in spring, apply sufficient base fertilizer. During the vigorous growth period, apply decomposed cake fertilizer water every 7 days to accelerate flower bud differentiation. When flower buds appear in the leaf axils, more fertilizer can be applied, mainly phosphorus and potassium fertilizer. During the peak flowering period in summer, apply alum fertilizer water once every 3 to 5 days, and spray 0.3% potassium dihydrogen phosphate every 7 days. From August to October, apply even more heavy fertilizer and heavy water, using fertilizer instead of water, watering with alum fertilizer water or cake fertilizer water.

Third, the sunshine duration should be long and the light should be strong. Bougainvillea loves light. When growing it, pay attention to ensuring daily light exposure of more than 9 hours. Under conditions of strong light and good ventilation, the flowering period of bougainvillea can reach 180 to 200 days.

Why bougainvillea does not bloom

There are many reasons why bougainvillea does not bloom. Below, the editor will introduce several common reasons why bougainvillea does not bloom and their solutions.

1. The flower pot is too small, which inhibits the growth of the bougainvillea root system and causes bougainvillea to be unable to bloom. At this time, bougainvillea should be repotted.

2. Bougainvillea has been in a dark environment for a long time and cannot get light, causing abnormal growth and therefore no flowering. At this time, bougainvillea should be moved to a place where it can receive sunlight for growing.

3. Bougainvillea has too many and too dense branches, causing nutrient loss and preventing flower buds from being triggered. At this time, the plant should be pruned appropriately.

4. Watering and fertilizing of bougainvillea have not been controlled well, causing the plant's leaves to be too lush and the flowers to be relatively few. At this time, attention should be paid to water control and fertilizer control, and phosphorus fertilizer should be applied appropriately.
