Speaking of bougainvillea maintenance, it is nothing more than polishing, pruning, watering and fertilizing. Bougainvillea needs to be treated differently before and after flowering, but there is still a big difference, so as to achieve proper maintenance and achieve the effect of flowering and bursting pots. Especially in lighting, fertilization and watering, it needs to be adjusted before and during flowering. Let's take a look at the specific differences!
1. Maintenance methods before flowering: ① water control; ② Sufficient illumination; ③ Apply thin fertilizer frequently.
1, water control
Bougainvillea grows very fast. As long as water, fertilizer and nutrients are sufficient, it can quickly branch and grow leaves, so that it will not differentiate into flower buds. Therefore, when bougainvillea blooms, it is too late to watch bougainvillea bloom again. Is it because the water is too good at ordinary times? What needs to be done is to strictly control water, especially some bougainvillea varieties of orchids. Only by controlling the water content can they start to differentiate flower buds and enter the flowering stage. Otherwise, it may not bloom for you all year round, but just keep growing branches and leaves.
When watering, you can't watch the pot soil watering, but observe the leaves of bougainvillea. Water only when the leaves are withered and drooping. The best time for this observation is at night. Water it thoroughly every time, and water it again the next time the leaves wilt and droop. After three or four times in a row, it can be seen that it begins to differentiate flower buds.
2. Adequate lighting
Bougainvillea likes sunshine. Even if you raise bougainvillea on the balcony, you need to go to Nanyang Terrace, where you can receive direct sunlight for a long time. Especially in the critical period of bougainvillea flower bud differentiation, there must be enough light for at least 6 hours. In other words, the longer the illumination time, the better the lighting effects, so there will be more differentiated flower buds.
If there is rainy weather at this stage of flower bud differentiation, as long as it is not continuous, the problem is not very big, but what if it is continuous rainy weather? If we are amateurs in bougainvillea cultivation, we can only admit that we are unlucky, and the number of flower buds formed will definitely decrease, and we can only wait until the next crop blooms. If you are a professional flower friend, you can use a fill light to supplement the lack of light during the day, but personally feel that it is not necessary.
3, thin fat and diligent application
When bougainvillea bougainvillea reaches bud stage, in addition to applying compound fertilizer or organic fertilizer to bougainvillea bougainvillea, foliar fertilizer is mainly phosphorus and potassium fertilizer. Supplementing phosphorus and potassium fertilizer to bougainvillea bougainvillea in bud stage can quickly promote flower bud differentiation. The types of fertilizers are basically potassium dihydrogen phosphate and Huaduoduo 2. The way of fertilization is through foliar absorption, which is faster and can be quickly absorbed and converted into nutrients through photosynthesis.
Potassium dihydrogen phosphate is a simple phosphorus and potassium fertilizer. Huaduoduo 2 contains many trace elements beneficial to flowers besides phosphorus and potassium. In domestic use, the effect of the two foliar fertilizers is similar. After all, various trace elements in the soil of the basin are also indispensable. Which one to use to see personal preference. Take some fertilizer and dilute it according to the dilution ratio of 800 1000 times. You can spray it after dilution. Generally speaking, it can be sprayed once a week for three to four weeks.
Second, the flowering period maintenance method: ① drying and pouring thoroughly; ② Avoid strong light; ③ Stop fertilization.
1, completely dried up
After the bougainvillea blooms formally, the maintenance method will be changed, especially watering, which needs to be restored to normal state, that is, drying and watering thoroughly. If the water is controlled again, the bougainvillea will sprout, which is not worth the loss. When watering, if you can't control the progress, you can insert a bamboo stick or chopsticks in the flowerpot. When watering, pull out the chopsticks and you will know whether it is necessary to water. Don't do it at this time.
Step 2 avoid strong light
Bougainvillea is sun-resistant, but its buds are not. At least after entering the summer, under the high temperature and strong light, the single flowering period of the bud will become faster and the color will be easily bleached by the sun. The correct way is to put a single sunshade net on the upper mask to reduce the light intensity, but there is no shortage of light. This can not only ensure sufficient illumination, but also prevent the bud from being damaged by strong light.
Step 3 stop fertilizing
There's nothing to say about this. Unfertilization at flowering stage is the basic requirement of all flowers. This is the common sense of flower growers. If you have to explain it, it is fertilization at flowering stage, which can promote the flowering speed of flower buds, speed up the flowering period of flower buds and make them wither ahead of time, and it is impossible to have the effect of flowering and bursting pots. In addition, fertilization at flowering stage will promote the germination of branches in advance and affect the flowering effect.
Conclusion:
The maintenance methods of bougainvillea before and after flowering are shared with you here. I'm a flower editor. I'm looking for interesting stories about flower cultivation, as well as all kinds of flower cultivation knowledge and skills for you. Let's plant flowers together!
