How do you breed evening primrose? Potted plant management techniques of evening primrose

Nocturnal incense is an ornamental plant native to the subtropics. It has a delicate fragrance, especially at night. It has a long flowering period and blooms from May to October. The flowers can not only smell incense and repel mosquitoes, but also can be eaten and used medicinally. It is often watched in the courtyard by potted plants. This article will mainly talk about its management technology.

First, basin soil management

Nocturnal incense is not resistant to waterlogging and likes loose, fertile and well-drained acid soil. Pot soil can be mixed with garden soil and rotten leaf soil at 1:2, which is suitable for paper strips to take root and sprout.

Second, temperature management

Nocturnal incense is not cold-resistant, and the lowest temperature of overwintering is not less than 8 °C. If the temperature is too low, the leaves will wither and fall off.

III. Lighting management

Although evening incense likes to have plenty of sunshine, it is taboo to be exposed to the sun and should be shaded or placed in a semi-overcast ventilated place in summer. Full light is available in other seasons.

IV. Watering management

Night incense like a humid environment, drought tolerance, fear of waterlogging, watering to wet but not waterlogging is better, keep the soil moist, summer growth is exuberant, can be watered once a day, while foliar spray to increase humidity. Stop watering after defoliation in winter and keep the soil microtide dry.

5. Fertilization management

Thin cake liquid fertilizer is applied every 10-15 days in the growing season, the water quality in the north is alkaline, alum fertilizer can be applied, and it can enter the flowering stage in May, and potassium dihydrogen phosphate can be sprayed on the leaf to supplement phosphorus and potassium fertilizer.

VI. Pruning management

After pruning every autumn, the branches are cut short by 10-15 cm, which promotes the development of more new branches, which is conducive to reducing the height, plump tree shape, and blooming more next year. At the same time cut off the secret branches and so on.

The fragrance of nocturnal incense is so strong that it will be uncomfortable for people to smell it for a long time, so it is not suitable to keep it indoors.

How do you plant evening primrose? The culture method of potted night incense

Yilaixiang is native to South China and grows in shrubs on hillsides. It is cultivated in all southern provinces. It likes warm and humid, sunny, well-ventilated, dry climate, good drainage and loose and fertile soil. Drought tolerance, barren tolerance, waterlogging resistance, cold tolerance, let's take a look at how to grow it in potted plants.

Preparation of basin soil

The potted soil is generally made of peat soil or rotten leaf soil with 3 portions of coarse river mud and 2 portions of coarse river mud and a small amount of farm manure. When potted, the bottom is about 1 inch 5 deeply filled with broken bricks to facilitate basin drainage, and the upper part is cultivated with mixed basin soil.

Culture environment

Potted night incense requires well-ventilated environmental conditions. From the beginning of May to the end of September, it is appropriate to put sufficient sunshine in the hospital or maintenance on the balcony. Although it likes adequate sunshine, it should avoid hot sun exposure at noon in summer.

Pot fertilization

In the process of its growth, liquid fertilizer should be applied every 10 to 15 days, and thin liquid fertilizer should be applied every half a month since late April, so that it can blossom continuously from the middle of May. If you can apply high efficiency humic acid liquid fertilizer such as Chunquan 883 or Huimanfeng, the effect is better.

Pot watering

Summer is the peak season for the growth of evening incense. Except for sufficient fertilizer, the basin soil must be kept moist and watered twice a day if necessary. If it is a seedling, it should be sprayed to the leaves once or twice a day.

Temperature management

Nocturnal incense potted in the middle and late October of every year should be moved into the greenhouse, the temperature of the greenhouse should be kept at 8 ℃ to 12 ℃. If the temperature is lower than 5 ℃, the leaves will wither and fall off until death.

Change the basin in time

The pot change of night incense should be carried out before coming out of the room in early April. When changing the pot, part of the old soil and roots should be removed, replaced with new culture soil, and heavy cutting should be carried out to promote the development of new branches. After changing the basin, you should keep the soil moist, but there can be no stagnant water in the basin. If you find that the tender leaves droop slightly after changing the basin, you should water them in time.

Plant shaping

Night incense needs to set up scaffolding in pot management, topping the plant in time to promote more branches, cut off the residual pedicels in time after blooming, add fertilizer, cut off withered branches and overdense branches after blooming, and truncate the overgrown branches.

Pest control

The main pests of night incense are mites and shellfish, and the diseases are Fusarium wilt. To control mites, we can use 800 times of anti-mite 23 EC, 73% of 2000 times of mites, 600 times of 600 times of dimethoate emulsion to control shell insects, and 600 times of Fusarium wilt and 50% carbendazim. If the wilt plant is found, it should be removed in time, taken out of the garden and burned, and the soil around the diseased plant should be spread with quicklime, and then replanted one month later.

After changing the basin, you should keep the soil moist, but there can be no stagnant water in the basin. If you find that the tender leaves droop slightly after changing the basin, you should water them in time.

7. Adjust plant shape

Scaffolding should be set up in cultivation and management, plants should be topped in time to promote more branches, residual pedicels should be cut off in time after blooming, fertilizer should be added, withered branches and overdense branches should be cut off after blooming, and overgrown branches should be truncated.

8. Pest control

At present, it is found that the main pests are mites and shellfish, and the disease is Fusarium wilt. In order to control mites, we can use anti-mite 23 EC 800x solution, 73% mites 2000 times solution and so on. To control shell insects, you can use 40% dimethoate emulsion 600-800 times.
