2. Key points of pot conservation of Magnolia mandshurica

1. Basin soil

Magnolia likes loose and fertile acidic and slightly acidic soil. Rotten leaf soil and vegetable garden soil can be mixed and cultivated in the same amount, and 50-150 grams of bone powder or nitrogen, phosphorus and potassium compound fertilizer can be added to the soil. The basin should be a little deeper and bigger, and some hard plastic foam blocks should be put at the bottom of the basin to enhance air permeability and drainage and prevent rotting roots. Turn the pot and change the soil once a year or every other year after flowering, keeping the persistent soil from 1x2 to 1x3.

2. Light and temperature

Purple magnolia like light, placed in the sunny courtyard, roof garden, most of the sun grows strong and luxuriant, although it can also grow under semi-shady conditions, but it is thin and has few flowers, and if it is too overcast, there are no flowers. It is hardy and can survive the winter outdoors in Beijing and its southern areas.

3. Water and fertilizer

Purple magnolia likes to be moist and afraid of waterlogging, so timely and appropriate watering is very important. When the Beginning of Spring blossoms, the potted soil remains moist but not wet; after flowering, the potted soil remains moist but not waterlogged; after defoliation, the potted soil remains moist but not dry. Do not be dry or waterlogging at any time, especially in the rainy season.

Magnolia likes fertilizer. Fertilization should seize the two key opportunities of 2 months before flowering and 5 months after flowering. Nitrogen, phosphorus and potassium compound fertilizer should be applied once every 10 days. The former makes buds expand and flowers bloom, while the latter promotes more pregnant buds and more flowers in the next spring. When the leaves fall in winter, the fertilizer mainly composed of phosphorus and potassium is applied once to enhance its ability of resisting cold and overwintering, with little or no application in the rest of the time. Avoid applying nitrogen fertilizer alone.

4. Pruning

The root of Magnolia mandshurica has strong sprouting and tillering ability. if it is not necessary to reproduce, cut along with the growth and keep 3 trunk plants in each pot. For branches that are too tall and too long, they can be cut short just after flowering. Because of their poor healing ability, they should be coated with sulfur powder for anticorrosion after cutting, and do not prune if it is not necessary. If there is no need to leave seeds for reproduction after flowering, the residual flowers should be cut off with pedicels.

5. Diseases and insect pests

Seedlings often suffer from blight. First of all, carry out soil disinfection treatment, 15-20 kg ferrous sulfate per mu can be used, ground and screened, evenly scattered on the border surface; pull out the diseased plants and burn them immediately. Leaf spot disease can be sprayed with 600-fold solution of 65 Dysen zinc wettable powder. There are mole cricket, ground tiger and other pests in the seedling stage, which can be trapped and killed with 2.5% trichlorfon powder mixed with poison bait. during the growing period, there are mainly harms such as spider moths, red spiders and shell insects, and can be sprayed and killed with 1500 times of omethoate EC.
