Big paulownia can blossom with a little light, and the more the grass is cut, the more luxuriant it grows.

Big rock tree, its flowers are very large, and bright incomparable, put in the corner can become extremely eye-catching flowers.

1. Conservation of the environment

Big paulownia, also known as snow mud, has a long flowering period, which can be seen from spring to the end of autumn. It is also a plant that blossoms all the year round. It also has a lot of flowers, rich varieties, various colors and different shapes.

The growth of paulownia needs a warm and humid environment, and it is enough to maintain a little scattered light. To avoid direct sunlight, it is necessary to maintain a ventilated and cool environment in summer.

2. Temperature and moisture

Paulownia has a certain heat resistance, when the summer temperature is more than 33 degrees, it is appropriate to spray water on the ground to cool down, and it is most suitable to keep the temperature between 18 and 25 degrees, which is favorable for it to blossom. In autumn and winter, it is best to keep the temperature at about 10 degrees. In this way, it can dormancy, preserve nutrients, and grow more vigorously in the next year.

Paulownia likes high air humidity, but does not like long-term watering, maintenance is more appropriate to avoid rain, avoid too much rain in summer, basin soil is dry and thoroughly poured, and can spray water around under the condition of ventilation in summer.

Pay attention to maintain humidity in winter and control watering and spraying to avoid too low temperature or too much humidity.

3. Selection of basin soil

The soil for planting paulownia should choose the slightly acidic soil which is loose, fertile and rich in humus to maintain the air permeability and drainage of the soil, and some granular organic fertilizer can be put on the bottom of the basin to make it have sufficient fertility during the growing period.

4. Lighting:

Paulownia is a semi-positive plant and likes semi-shady environment. Maintenance attention do not let it exposure, summer is to shade maintenance, to avoid direct sunlight, it is easy to sunburn, there is a little weak scattered light.

5. Proper fertilization:

Paulownia likes thin fertilizer, especially in the growing season, which can be used alternately with phosphorus and potassium fertilizer to ensure luxuriant branches and leaves and keep blooming.

During the growing period, thin organic liquid fertilizer is generally given once a week. After seeing flower buds, it is necessary to apply more phosphorus and potassium fertilizer to avoid fertilizer sticking to the flowers and leaves, which is easy to cause fat injury, and remember not to give thick fertilizer.

6. Introduction to reproduction

Paulownia can cut its healthy leaves directly, leave its petiole 1 cm and insert it obliquely into the clean river sand. The 1Rue 3 of the leaf surface is inserted in the river sand, and the 2RPG 3 stays on the ground surface to properly shade and maintain a certain humidity. Under the temperature of about 22 ℃, it can take root in 15 days, and the seedlings can be transplanted into a small pot after transplanting.

2 the more the drug grass is cut, the more luxuriant it grows, and if you pinch a section of grass and throw it into the soil, you can live.

Poisonous grass can also be sterilized by removing formaldehyde, radon, benzene, ammonia, sulfur dioxide, smoke, odor and carbon dioxide from the air.

1. Conservation of the environment

Drug-addicted grass is actually wrinkled mint, a variant of mint, but it is more drought-resistant, cold-resistant and shade-tolerant than mint. It can be pruned and pinched at will, and it can grow more luxuriantly.

It likes to have scattered light, warm and moist environment, and can keep the basin soil dry and irrigated during the growing period.

Winter maintenance is appropriate to keep warm, as long as the temperature is kept above 0 degrees, the poison grass will not freeze to death. After the summer temperature is higher than 30 degrees, it can often spray water on and around the leaves to cool down, maintain a warm and moist environment, and it can maintain exuberant growth.

2. Proper moisture

When the summer temperature is high, the water consumption is especially fast, and it can be watered once a day. In other seasons, it is usually about 3 days to water thoroughly. If you find that the leaves are a little wilting, you need to replenish the water in time.

3. Proper pruning

The more drug-addicted grass is pruned, the more luxuriant its branches and leaves will grow. During the growing period, it can be pruned once a week, or constantly pinched at the top.

Diseased leaves and withered branches should also be cut off in time, and carbendazim should be sprayed in time. Don't prune frequently after the weather gets cooler in autumn.

4. Introduction to reproduction

Drug addicts are generally propagated by cuttings, or directly by striping, pressing a longer stem directly into the soil, wait for it to grow roots, and then cut off and transplant, the survival rate is basically 100%.

Cuttage propagation is also very simple, directly cut a stem about 7cm long, remove the leaves at the bottom, soak in water directly, change the water once every 2-3 days, and grow roots in a week, and you can pot it in two weeks.

On the other hand, soil culture cuttings should keep the soil moist and keep them in a ventilated and shaded place, and they can resume growth in 2 weeks.
