How to raise potted morning glory?

Morning glory is a common ornamental plant, also known as bowl public flower, trumpet flower, etc. it is an annual twining herb of the genus Petunia in the petal family. Morning glory is usually sown in spring and blossoms in summer and autumn. There are many varieties, such as blue, scarlet, peach red, purple and so on. There are also mixed colors, and there are many changes at the edge of petals. Let's take a look at how to raise petals in potted petals.

The growth environment of morning glory

Morning glory is native to tropical America and has been widely planted in tropical and subtropical regions. Except for some provinces in northwest and northeast China, morning glory is distributed in most areas with strong adaptability, sufficient sunshine and tolerance to semi-shade. Like warm and cool, can also withstand heat and high temperature, but not cold, afraid of frost. Like Feimei loose soil pile, can withstand moisture and dry early, more resistant to salt and alkali. The suitable temperature for seed germination is 18-23 ℃, and the seedlings can grow when the temperature is above 10 ℃.

Reproduction methods in growing environment

1. Sowing: it is better to sow morning glory from October to November in autumn, and the temperature is about 20 ℃, and the seedlings can be seen after about 10 days. You need to move indoors in winter to ensure a smooth winter. If the spring sowing time is chosen in late April, it can blossom in summer, and if the sowing time is earlier, it must be carried out indoors to prevent rotting roots caused by rainy weather. When sowing, use a seedling tray to ensure sufficient water supply, and cover the surface with a thin layer of fine sand. If you need moisturizing, you can cover it with glass or white paper. The seedling time is about 60 days.

2. Cutting: the suitable temperature for morning glory hairy root is 20-25 ℃, and the cutting survival rate is higher in May-June and August-September. Cuttings should be strong disease-free branches, can be cut from the base of the node, the length is about 10 cm, the cut should be flat, the upper part of the cuttings can retain 2-3 leaves, the leaves are too large can be cut off half. When cutting, pay attention to basin soil disinfection to prevent easy infection and decay of cuttings, cuttage depth is about 1.5cm, place in a low light place, pay attention to spray water to keep moist, take root for about two weeks when the ground temperature is kept at about 20 ℃, and transplant can be carried out after about 30 days.

How to raise potted morning glory?

1. Planting: when the morning glory seedlings grow out of 6 to 7 leaves, the whole block will be removed and replaced with a billet basin (24 cm in inner diameter). The pot soil should be fertilized and cultivated, and 50 grams of hooves should be applied as base fertilizer and watered after planting. Morning glory is not afraid of heavy fertilizer, you can use horseshoe, cooked hemp residue and so on as base fertilizer. The development of the root system of morning glory needs temperature, and it is better to absorb heat with black basin than with red basin.

2. Soil: morning glory pots should be planted in early April, with half of ordinary culture soil and half of plain sandy soil. When making a pot, the lower end of the main root will be removed 1 cm, with ordinary culture soil planted in the No. 2 pot, one plant per pot. Pay attention to the open field transplantation of Petunia, never touch the main root, the seedling should be small, should be early, the bigger the better.

3. Water and fertilizer: morning glory culture should choose the culture soil with good drainage, give it to the environment with sufficient sunshine and good ventilation, irrigate when the surface of the potted soil is slightly dry during the growth period, and apply dilute liquid fertilizer once every half a month, nitrogen fertilizer should not be too much, so as to avoid luxuriant stems and leaves. Potted plants need to be supported by pillars.

4. Pick the heart: after waiting for the potted soil to be implemented, morning glory inserts a 1-meter-long thin bamboo pole in the center of the basin. Then use about 3 meters of lead wire, one end of the soil surface wrapped around the bamboo pole, and then spiral upward from the basin mouth to form a large and small symmetrical tower-shaped spiral frame. The upper end of the wire is fixed at the top of the bamboo pole. Morning glory is a left-handed plant, the spiral direction of the lead wire must be in line with the habit of morning glory winding to the left, when the main vine climbs along the lead wire to the top of the pole, pick the top. The lateral vine pinches every 6 to 7 leaves, which can make the flowers big and blossom continuously.

5. Diseases and insect pests: morning glory is mainly prone to white rust, the main sites are leaves, petioles and tender stems, and the damaged leaves have light green spots on the leaves at the initial stage. In this case, the diseased plants can be pulled out and destroyed in time to reduce the infection of seeds. Leave disease-free seeds as propagation seeds and disinfect seeds before sowing to avoid rotation with plants of Convolvulaceae. Spraying 1% Bordeaux solution or 50% Phytophthora 500 times solution at the initial stage of the disease, spraying once every 10 to 15 days has a better control effect.

6. Modeling

① dwarfing cultivation: when the cotyledons or the first or second true leaves of morning glory seedlings are unfolded, the terminal bud is removed in time to make the plants dwarf and erect, so that the leaves and axils of cotyledons and true leaves can bud and blossom.

② bracket: when the plant grows to a certain height, it should be made of a thin bamboo pole to make it climb and grow, and can be tied into various shapes according to personal preference for artistic modeling. When modeling, it should be noted that the winding direction of the lead wire and the support wound from right to left toward the stem.
