After autumn, the weather is cool, the sun is abundant, and the rain is less, the temperature difference between day and night increases, and a bougainvillea bursts. Because of the blessing of the temperature difference between day and night, the flower color and flower volume are comparable to spring. The maintenance is done well, and the flower quality can reach the best year-round. Therefore, we cannot be lazy in growing bougainvillea in autumn. Master the correct maintenance methods and maintain it on demand, so that it can bloom the most beautiful flowers.
In autumn, bougainvillea should be "brutally raised", and the three ruthless and one control should be done in place, and there is no need to worry that it will not bloom
1. Prune
In autumn, bougainvillea should be pruned reasonably, because bougainvillea is a plant with new branches and flowers. Only by pruning appropriately can it stimulate its sprouts and growth of new buds, so that it has the basic conditions for flowering. Therefore, in late September, except for bougainvillea that is growing buds, newly pruned, or in the midst of the flowering period, other bougainvillea that is in the tail flowering period, has not bloomed for a long time, has no new buds and leaves, and some are too long, can be appropriately pruned.
a: Pruning method for bougainvillea in the tail flowering period
For bougainvillea near the tail flowering period, that is, the plum blossom period has passed, there are only a few branches and scattered flowers. For such bougainvillea, we can cut it hard, cut off all the remaining flowers, and cut off some weak branches, sick branches, long branches, inner branches that affect ventilation and light, and some withered leaves. The branches can be cut according to the size of the plant, and they can be cut in a more coordinated manner.
It should be noted that many people are reluctant to cut off the blooming branches, which will really affect the blooming of autumn flowers, because it will be too late to urge them to bloom again, so don’t be reluctant, otherwise you will lose the big one because of the small.
b: Long-term sprouts, no blooming bougainvillea
The bougainvillea raised by many people is in a state of long-term "scattered seedlings". Such bougainvillea does not grow or grow, does not bloom, and the branches have been capped, and it will be difficult to bloom even if it is urged. For such bougainvillea, the first thing to do is to cut the branches short to stimulate the new buds to grow from the leaf axilla of the leaves under the cut opening. With new buds, they have the ability to bloom. Then enter the flowering urging, and the effect will be faster. As for how much each branch is cut, it can be determined by the condition of the whole plant. If the overall structure is relatively coordinated and the plant shape is maintained well, then we can cut it from one or two leaves. There is no need to cut it too short. If the plant shape is not maintained well, then we can cut more branches and fewer short branches.
c: The puppy bougainvillea
There is a lot of rain in summer. Many people's home-grown bougainvillea is in a state of crazy growth of branches and leaves, with dense branches and leaves, and the whole look green, but it doesn't bloom. For such bougainvillea, you need to do a pruning one time, and cut off all the branches that grow too densely and lushly, and some branches that affect ventilation must also be cut off. Cutting it hard can make its plant look better, reduce nutrient consumption, promote the growth of new buds, and allow it to bloom quickly.
2. Bathing more sun, entering the room late
Bougainvillea is a light-loving flower, and the demand for light is still very large. To raise bougainvillea at home, you must give it sufficient light. Except for the high temperature in summer, you cannot expose it to the sun. You must avoid direct light from the high temperature at noon. You must burn more at other times. The more you burn, the stronger your flowering ability. After the autumn cools, bougainvillea must be kept in full light regardless of whether it is blooming or not. The weather is high and cool in autumn, the temperature is suitable, and the light is sufficient. Some flower lovers' bougainvillea does not bloom in summer. In autumn, give it plenty of sunshine and sunbathing, which is completely possible to bloom.
Farming bougainvillea outdoors, place it in the sunny place. As long as the temperature is not lower than 15 degrees at night, don’t rush to enter the room. A moderate temperature difference between day and night can make it bloom more beautifully. Whether it is the fullness of the color or the amount of flowers, it will be better than bougainvillea that does not have a temperature difference between day and night. Therefore, when growing bougainvillea outdoors, you should dry more and enter the room late.
The bougainvillea grown indoors are of course placed on the south balcony or south windowsill with the most sunlight at home. They should bask in the sun more often, and try not to close the windows at night, giving it a temperature difference between day and night of 5-10 degrees, and giving it a better flowering quality.
3. Fierce water control
plants bloom, and their nature is to reproduce. Controlling water in moderation can make it feel a certain growth crisis, thereby differentiating flower buds and blooming directly. Although bougainvillea does not mainly reproduce seeds, it also has the nature of a plant. Controlling water and drying can promote its early differentiation of flower buds.
Control water for bougainvillea. It is not that you don’t water at all, but that you must water it in a moderate manner. Before blooming, try to keep it in a "thirsty" state. Generally, wait for the soil to dry out and wait for a day or two. The most intuitive thing is to look at its leaves. You can wait until the leaves are completely wilted before watering. It should be noted that watering must be thoroughly watered, and do not water half water. Generally, water is controlled repeatedly, 4-5 times, and a pot of strong and nutritious bougainvillea can differentiate into flower buds.
4, apply fertilizer frequently
As the saying goes, "A crop is all about fertilizer, and it is the main source of the family." From this we can see that plants need to consume a lot of nutrients when they bloom. Under the same conditions, if the nutrients are sufficient, the quality of flowering will be much higher. The flowering volume of bougainvillea is large and the flowering period is long (one batch of flowers can last for twenty or thirty days), and the corresponding nutrients are needed. So how to fertilize bougainvillea? You can start from the following three aspects.
Soil and base fertilizer should be used well
Soil is the basis for the growth of bougainvillea and the main source of its absorption of nutrients. Therefore, it is very important to plant bougainvillea, which is the key to the soil. There is no problem with ground-planted bougainvillea, but the base fertilizer should be applied on time every year. For potted bougainvillea, it is best to turn a pot every year and change the soil once a year. Because potted soil is generally used for about one year, the nutrients in the soil will be consumed. If it continues to use, it will stick to the plate and cannot provide nutrients, but it will also affect watering and fertilization.
The soil of bougainvillea is just like using ordinary acid nutrient soil. As long as it is guaranteed to have good breathability and light fertilizer, it can be prepared by yourself (can be prepared with garden soil, leaf rot soil, perlite or river sand in a ratio of 3:1:1), or you can directly purchase special bougainvillea. No matter how the soil is prepared, it should be noted that before putting in the pot, you must add 1 portion of organic fertilizer (the best is rotten cake fertilizer, it is best not to use fast-acting fertilizer, because the fertilizer effect is fast, which can easily lead to excessive growth of branches and leaves) as base fertilizer. The best season to repot bougainvillea is spring and autumn, and it is recommended to do it as soon as possible.
Base fertilizer should be applied regularly, don't be lazy
If a plant grows vigorously for a long time, you must fertilize regularly to ensure that it has sufficient nutrients to grow. When the temperature is right, bougainvillea grows almost all year round and flowers can be seen all year round, so there should be more demand for nutrients. So you must apply base fertilizer regularly and don’t be lazy.
base fertilizer is generally made of multi-element compound fertilizer with balanced nitrogen, phosphorus and potassium, or organic fertilizer. If you raise bougainvillea, you can use special fertilizer for bougainvillea. No matter which kind of fertilizer is used, you must follow the instructions and insist on feeding regularly. For potted bougainvillea, I personally recommend using more organic fertilizer. Although organic fertilizer is not as effective as fast-acting fertilizer, its fertilizer effect is gentle and long-lasting, and can maintain the acidity of the soil and improve the looseness of the soil. Long-term use can increase the service life of the soil. In the long run, it is extremely beneficial to the growth of bougainvillea and can achieve twice the result with half the effort.
Flower-promoting fertilizer is indispensable
Flower-promoting fertilizer generally refers to phosphorus and potassium compound fertilizer. Because plants bloom, sufficient phosphorus and potassium fertilizer is needed. Common phosphorus and potassium fertilizers on the market include potassium dihydrogen phosphate and Huaduoduo No. 2, with similar prices and similar flower-promoting effects. They have good flower-promoting effects when used properly.
is not difficult to use. You can dilute the phosphorus and potassium compound fertilizer or the flower-promoting fertilizer for bougainvillea, according to the ratio of the instructions to mix it into an aqueous solution. Taking potassium dihydrogen phosphate as an example, it is generally mixed into an aqueous solution of 1:1000, and directly replace water to irrigate the roots or spray the leaves. It is generally used once every 7-10 days. When the base fertilizer is sufficient, it is generally used four or five times to grow flower buds.
It should be noted that after applying phosphorus and potassium compound fertilizer three times in a row, the compound fertilizer should be applied once, otherwise the growth is weak, which will also affect the quality of flowering.
is what I shared today: "In autumn, bougainvillea should be "abuse and raise", and do the three ruthlessness and one control well, and don't be afraid that it will not bloom." I hope you like it, see you next time!
