How to trim the branches and leaves of Tripterygium paniculata after the flower fade

With regard to plant pruning, it is very important to choose the right time. Generally speaking, we will judge according to the growth stage of the plant, but the growth habits and the division of the growth stage of each plant are different. so we need to have a more accurate grasp of the characteristics of plants before pruning.

How to prune the branches and leaves of paulownia

1. Pruning before flowering

Generally, the branches and buds are pruned before flowering, and the way of coring is taken.

Pick the heart, is to remove the top flower branches, so as to promote the growth of more lateral branches, so as to produce more flowers.

Early plucking is beneficial to early shaping and flowering. After picking the heart, three new buds with similar height and suitable position will be selected to ensure the smooth opening of the flowers.

2. Pruning when paulownia blossoms

After flowering, if the leaves around the flowers hinder the normal growth of the flowers, you can cut off all or half of the leaves according to the actual situation and needs.

Pruning the leaves in this way can make all the flowers bloom at the top of the plant, forming a bouquet, and the ornamental effect will be better.

The pruned paulownia can produce up to 18 flowers at a time. Among them, a large paulownia cultivated in a 12 cm flowerpot is no more than 15 cm in height and has only 2 branches, that is, 16 flowers bloom at the same time, which is very beautiful.

3. Pruning after flowering

After flowering, if the cultivated soil is fertile and properly managed, it will pull out the second batch of buds.

After flowering, if there is no need to keep seeds, it is best to cut off the flower stem and control the loss of nutrients, which is conducive to the continued flowering and tuber growth and development.

After flowering, enter the winter, to keep the tuber of Caulownia, select a section of leafless stem, the length is about 3 ℃ 4 cm, to store sand in time, keep the temperature not lower than 5 ℃.

During the overwintering period, the sandy soil should not be too wet, otherwise the corms will rot. If the sandy soil is too dry, spray an appropriate amount of water to prevent stem dryness. When spring is warm and flowers bloom, the tubers of paulownia will sprout and leave new buds as needed to enter a new round of maintenance and pruning.

How to prune the big paulownia after the flowers are shedding?

When to trim

When pruning, be sure to pay attention to whether there are new buds on the main stem of Caulownia. If there are no new buds, then nutrients will always be supplied to the bulbs and bulbs, which will make the bulbs and bulbs thick, but you can keep it until the temperature is right. If there are new buds, as long as the temperature is right, it will grow and blossom soon, and can make the plant shape more perfect, easy to watch and cultivate.

Second, time and temperature control

If you have entered winter and the temperature is low or even reaches five degrees Celsius, even new buds will not sprout into new plants after pruning. At this time, you should retain it and select a leafless stem of suitable length. About 3-4 cm of stem is stored in sand and wait for later culture. Attention should be paid to keeping the temperature when storing sand, and it is most appropriate that it is not lower than no degree Celsius.

If the sandy soil is to maintain proper moisture, too wet will lead to rot, while if it is too dry, you need to spray a little water to prevent the stem from drying up.

After the tuber sprouted, the bud should be pruned at this time to facilitate the better growth of the plant.

Third, the part of trimming

After the plant blossoms, many people may grow by the flower diameter, but in fact, pruning the flower diameter is more appropriate, which can reduce the waste of nutrients and accumulate more strength for the growth of flowers. When the lateral buds grow up, only the main stem and lateral buds can be retained to promote the lateral buds to blossom quickly. The lateral buds that grow after beheading will be stronger and the overall shape will be better. Not only does the flower need to be pruned after fade, but under daily circumstances, if the leaf of the flower affects the growth of the flower, it needs to be pruned. For the plants before flowering, the apical branches and buds can also be coring to promote lateral growth. If yellow and spotted leaves are found, it is necessary to identify whether the plant is sick or not, and prune the problematic leaves in time to prevent damage to the health of the whole plant.

Before pruning, in order to make it more ornamental, the temperature can be slightly lowered during the bud, the flowering can be prolonged, and the plant metabolism can be reduced.

When will the paulownia blossom

The flowers of paulownia are terminal or axillary on the branches, and the Corolla is bell-shaped; the colors of the flowers are pink, red, purple-blue, white, complex and so on, and the flowers are large. One tree can blossom as many as dozens of flowers. The flowering period of paulownia is between April and November, and the flowering period is longer.

How to prolong the flowering period of paulownia

I. temperature

Generally speaking, this kind of flower needs an ambient temperature of 18 to 25 degrees from January to October and 10 to 12 degrees after October. Accordingly, we can give it a growth environment of 18 to 25 degrees during its flowering, so that it can grow more comfortably, and the flowering time will naturally be prolonged.

Second, lighting

This kind of plant usually needs shade to grow and can not adapt to the strong light. During its flowering period, we should increase the time of shading to prevent it from receiving too much light to prevent it from growing normally. This practice can effectively prevent the flower from withering quickly, thus prolonging its flowering period.

III. Matrix

If you want to prolong its flowering period, its roots must be nurtured when it is cultivated. Its root system is relatively weak, showing a capillary state, and can not adapt to the soil that is too wet or very sticky, so it should have been replaced with loose soil with good drainage and irrigation capacity and good air permeability when breeding. We can cultivate it with rotten foliage soil, vermiculite, pine needles, rotten mushroom fertilizer and so on. This can also effectively provide nutrition for the gestation of its buds.

IV. Fertilization

This kind of flower needs a lot of fertilizer when it blossoms, and if it wants to prolong its flowering period, it will consume more nutrients, so we should replenish it in time. From the time its leaves unfold to before it blossoms, thin cake fertilizer must be added every other week, and bone powder or phosphate fertilizer should be applied when flower buds are formed.

Although the flowering period of paulownia is relatively long, it may lead to the change of flowering due to the influence of growth environment and climate, so we can properly according to the growth habits of paulownia. Manage and control the flowering period of paulownia.
