Paulownia, also known as Liuxueni, snow mud, is a common perennial herb of the genus Tripterygium in China. It is deeply loved by flower friends because of its rich and beautiful colors and beautiful flowers. How much is a bag of paulownia seeds? How do you plant it? When will it blossom after planting? How to cut off the head after blooming?

Seed price:

Large paulownia seeds are generally purchased in small bags, about 10 or 20 in a small bag, the price of 10 seeds in a bag is about 5 yuan, and 20 seeds is about 10 yuan. They are generally purchased in the flower market or online.

How do you plant it?

1. Seed selection

If you want paulownia to blossom more, we need those imported hybrid varieties with luxuriant flowering, short and strong plant type, strong resistance and easy maintenance, and single-petal varieties have more specific petal varieties.

2. Seed acquisition

It is difficult for paulownia to self-pollinate. In order to obtain excellent seeds, artificial pollination should be carried out. In the flowering stage, the pollen of stamens was collected and painted on the stigma of pistil with a brush. The seeds will mature about 35 days after pollination, and the seeds will be removed and dried and stored.

3. Sowing method

Before sowing, soak the seed in water for 24 hours to promote its germination ahead of time. The best combination of basin soil is rotten leaf soil, vegetable garden soil and fine sand. After leveling the soil, spread seeds evenly, soak the pot in shallow water and remove it, cover it with glass and place it in a semi-shaded place to maintain a humidity of 18-20 ℃. Seedlings can emerge in about 10 days, and then let the tree gradually see the sun, but to avoid direct sunlight, often spray, maintain humidity, apply thin cake fertilizer and water every 10 days or so, generally blossom about 6 months after sowing.

Flowering time:

The flowers of paulownia are terminal or axillary on the branches, and the Corolla is bell-shaped; the flowering period is between April and November, and the flowering period is longer. The colors of its flowers are pink, red, purplish blue, white, complex colors and other colors and large flowers, a large paulownia can blossom as many as dozens of flowers, it is really beautiful. A large paulownia can blossom dozens of flowers, blooming from April to November, and the flowering period lasts for several months. But blossoms once a year.

How to cut off the head after blooming?

Generally speaking, a lot of new buds will be sent out at the bottom of the tree after flowering. We must pay attention to these new buds if there are no new buds, do not easily cut off the head, otherwise it will be very difficult to recover.

In fact, there are two ways to cut off the head of the big paulownia after flowering, one is to cut off the head, a little harder, and the other is to pinch off the old pedicel.

Both methods can be used, flower friends choose. If beheading is carried out on a sunny day after full bloom and failure, at least one pair of leaves and 1-2 cm stalks should be left. There is no need to water 3 or 5 days after beheading, lest wound infection lead to rotten balls. If there is no new bud, it will sprout again in 10 days and blossom again in about 2-3 months. The cut leaves can be inserted.

Whether it is the new bud at the bottom or the new bud after beheading, if it is not for reproduction, you can leave only one of the buds and remove the weak buds, which is conducive to the concentration of nutrients and the blooming of more and more flowers.

Culture methods:

1. Soil: paulownia likes loose, fertile and good water retention humus soil, which should be cultivated with slightly acidic soil rich in humus and loose. It is often prepared with 1 part perlite, 1 part of river sand and 3 parts of rotten leaf soil plus a small amount of rotten and sun-dried fine broken poultry manure. Potted paulownia is commonly used as a mixed substrate of rotten leaf soil, coarse sand and vermiculite.

2. Temperature: the suitable temperature for the growth of paulownia is 10-25 ℃. There are different requirements in different seasons, 18: 25 ℃ from January to October, and 10: 12 ℃ from October to January. The suitable temperature can make the leaves grow luxuriantly and green, and the flowers are large and bright. When the plant is withered and dormant, take out the bulb and hide it in the slightly moist sand.

3. Illumination: paulownia is a semi-positive plant, which should be properly shaded to avoid direct light. There should be plenty of sunshine in the seedling stage in winter, and it must be carefully maintained in a ventilated shade shed with scattered light in summer, the light in the growing period should not be too strong, the sunshading time should be properly prolonged when flowering, and the basin soil should be kept slightly dry during the dormant period in winter.

4. Watering: the big paulownia flowers and leaves are fluffy, and once they are stained with water droplets, they are very perishable, so do not spray water on the flowers and leaves. It is best to use the immersion method to water. Usually appropriate amount of watering, too much is easy to cause tuber rot, leaves withered and yellow, or even the whole plant death. During the period of high temperature in summer, it should be watered once or twice a day, and rain must be avoided during flowering.

5. Fertilization: paulownia should apply mature thin organic liquid fertilizer once a week from leaf expansion to flowering, increase phosphate fertilizer after flower bud formation, do not stain the leaf surface, and spray clear water once after each fertilization. Thin cake fertilizer should be applied every 10-15 days from leaf extension to flowering, and bone powder or superphosphate should be added during flower bud formation.

6. Insect pests: leaf snail pests are easy to occur in the process of breeding, which mainly harm the roots, stems and leaves, making the leaves yellowing and shedding, which will lead to death in serious cases. When it is found that there are red spiders on the leaves, 5% nisolone emulsion can be sprayed 1000 times, the control effect is very good. It is generally sprayed once a week for 2 times in a row.
