How to plant Magnolia liliiflora? A full analysis of scientific cultivation techniques

1. Soil. You can mix leaf mold and garden soil in equal amounts as the growing medium, and add 50-150 grams of bone meal or NPK compound fertilizer to the soil. The pot should be slightly deeper and larger, and put some broken hard plastic foam blocks at the bottom of the pot to enhance air permeability and drainage and prevent root rot. Repot and change the soil once every year or every other year after flowering, keeping 1/3-1/2 of the old soil.

2. Watering. Timely and appropriate watering is very important. From the Beginning of Spring to flowering, keep the potting soil moist but not wet; after flowering, keep the potting soil moist but not waterlogged; after leaf drop, keep the potting soil slightly moist and not dry. At no time should it be drought-stricken or waterlogged; especially in the rainy season, pay attention to drainage and waterlogging prevention.

3. Fertilizing. Grasp the two key times, the 2 months before flowering and the 5 months after flowering, and apply NPK compound fertilizer once every 10 days. Fertilizing in February makes the buds swell and the flowers open; fertilizing in May promotes more bud formation, so there will be more flowers in the spring of the following year. When leaves drop in early winter, apply a fertilizer mainly of phosphorus and potassium once to enhance its cold resistance for overwintering, and apply little or none at other times. Never apply nitrogen fertilizer alone.

4. Light. Place it in a sunny courtyard or roof garden for care; with more sunlight it grows robustly and luxuriantly. It can also grow under semi-shade conditions, but it will be thinner and bear fewer flowers, and in too shady conditions it will not bloom. Magnolia liliiflora is relatively cold-resistant, and in regions at and south of it can overwinter outdoors.

In the valleys of China, Magnolia liliiflora is a very precious ornamental flower, mainly used for flower viewing, so what is the flower language of Magnolia liliiflora? The answer is: “fragrant sentiments, handsome bearing”, because it is famous for its elegant fragrance and graceful posture.

What does Magnolia liliiflora represent

Magnolia liliiflora represents appreciation of the other person, because when its buds are about to open, its appearance looks like an upright writing brush. If you give Magnolia liliiflora to someone, it means praising the other person for their talent and expresses appreciation.

How long is the flowering period of Magnolia liliiflora

Botanists have found through research that the flowering period of Magnolia liliiflora is generally in spring, that is, March to April. The flowering time is greatly affected by temperature. For example, Magnolia liliiflora cultivated in a greenhouse may bloom in March, while those cultivated in the open field will bloom in April.

How to make Magnolia liliiflora bloom more

1. Reasonable fertilizing

The number of flower buds is directly related to the number of flowering branches of Magnolia liliiflora. The more flowering branches, the more flower buds there may be, and naturally the more flowers will bloom. This requires reasonable fertilizing. For example, applying compound fertilizer once every 10 days before flowering can promote flower bud growth. For details, you can refer to the detailed introduction in how to fertilize Magnolia liliiflora.

2. Scientific pruning

Many plants usually need shaping to keep a beautiful plant form, but Magnolia liliiflora is not like this. Excessive pruning will cut off some flowering branches, so the pruning method for Magnolia liliiflora is especially important. Generally, after the flowers fade, you need to cut off branches longer than 15 cm that are too long and too dense, and there is no need to cut as they grow.

3. Control light and temperature

As we introduced earlier, the flowering of Magnolia liliiflora is mainly affected by temperature, so controlling the temperature at 15-20 degrees can make it bloom more. In addition, light must also be sufficient. The planting location is best with sun-facing base fertilizer. In a semi-shade environment it will have very few flowers, and in too dark conditions it may not bloom.

What to do if Magnolia liliiflora gets insects, pest and disease control of Magnolia liliiflora/fertilizing is key

Magnolia liliiflora has quite good cold resistance, so it has relatively few cases of pests and diseases. However, if Magnolia liliiflora is cultivated completely incorrectly, or the environment is too harsh, pests and disease spots will often harm Magnolia liliiflora. So what should be done if Magnolia liliiflora gets insects? Let us look at the pest and disease control of Magnolia liliiflora.

Pest and disease control of Magnolia liliiflora

I. Diseases of Magnolia liliiflora

1. Yellowing disease of Magnolia liliiflora

Main symptoms: The leaves of Magnolia liliiflora gradually change from green to yellow. Chlorophyll gradually decreases due to the disease; the leaves first turn yellow and then gradually turn white. The plant grows slowly, and in severe cases the plant may die. This is one of the most harmful diseases in the pest and disease control of Magnolia liliiflora.

Cause: Yellowing disease is generally caused by bacteria, viruses, nematodes, and so on, and can also be caused by extremely insufficient nutrients, such as nitrogen deficiency, sulfur deficiency, drought, and so on.

Control measures: Strengthen cultivation management, pay attention to reasonable fertilizing, timely watering, and so on; check the soil before planting, and if the quality is too poor it should be improved through measures such as fertilizing. In addition, a 0.1% ferrous sulfate solution can be used for leaf spraying for prevention.

2. Anthracnose of Magnolia liliiflora

Main symptoms: Nearly round or irregular disease spots appear on the leaves of Magnolia liliiflora, often on the leaf margins, with a diameter of 10-20 mm. The spots are first grayish white with dark brown edges, and then dense small black dots appear.

Cause: Too high temperature, poor ventilation, too little fertilizing and watering, and the leaves are infected by Colletotrichum fungi. The small black dots are fungal masses.

Control measures: 1. Pay attention to reasonable care, such as scientific fertilizing, watering, and maintaining a ventilated environment, and avoid excessively high environmental temperatures; 2. When diseased plants are found, promptly spray 50% thiophanate wettable powder at 500-600 times dilution, or 50% carbendazim at 500-600 times dilution, or Bordeaux mixture at 1:2:150-200 times dilution, or 50% tuijunte at 800 times dilution.

II. Insect pests of Magnolia liliiflora

1. Red spider mite

In the pest and disease control of Magnolia liliiflora, the red spider mite is one of the most harmful pests. After Magnolia liliiflora unfolds its leaves, it moves onto the leaves and begins to damage them from both sides of the main vein on the underside of the leaves, using the leaves as its main food source.

Control measures: 1. When the leaf color is found to be abnormal, carefully check the underside of the leaves. If only a small number of pests appear, remove the diseased leaves as early as possible; 2. Use 40% dicofol emulsifiable concentrate at 1000-1500 times dilution, or 20% miediejing wettable powder at 2000 times dilution for spraying to eliminate the pests.

2. Psilogramma menephron

Psilogramma menephron usually forages in the early morning and hides in dark places during the day. It feeds on the epidermis of Magnolia liliiflora leaves, and then the entire leaf may be eaten bare. Not only that, the growth of the plant will also be hindered and flowering will decrease.

Control measures: 1. Turn the soil regularly, which can kill overwintering pupae; 2. When Psilogramma menephron appears more seriously, spray 20% miman suspension concentrate at 1500 to 2000 times dilution, 50% zinc phoxim at 2500 times dilution, or 80% dichlorvos emulsifiable concentrate at 800 to 1000 times dilution for control.
