In the great poet qu Yuan's Lisao, there is a good sentence that "drink magnolia in the morning and drop the chrysanthemum in the evening" to show its noble personality.

Wild magnolia or Magnolia magnolia was used as rootstock for grafting, cut or split before sprouting in spring, and grafted with buds from May to August. A small amount of family reproduction, it is appropriate to use high-altitude striping method, select strong and good-shaped branches, under the node for circular peeling, up to xylem, internal with moss or plain soil, externally wrapped with plastic film, often keep the substrate wet. The spring pressure is cut off after autumn, and the autumn pressure is cut off in the following spring, and then planted.

Breeding and transplanting of Magnolia mandshurica

After the sowing seedlings are unearthed, the sun should be shaded properly in the middle of summer for 2 years, and the cold should be protected in the north after entering winter. Transplanting does not hurt the root system, large seedlings should be planted with soil balls, dig large holes, deep fertilization, appropriate deep planting can inhibit tillering and be beneficial to growth. It is better to transplant before sprouting, or before flowers are just shedding, or before spreading leaves.

Magnolia mandshurica fertilization:

In addition to paying attention to base fertilizer, acid soil should apply more phosphate fertilizer appropriately. Topdressing before and after flowering is particularly important, the former promotes flowers in full bloom, the latter is beneficial to pregnant buds, and the period of topdressing is in late February and May.

Magnolia water management:

Summer is the growing season of Magnolia. High temperature and drought not only affect vegetative growth, but also cause flower buds to shrink and fall off, affecting flowering in the coming year. Therefore, attention should be paid to irrigation and soil moisture conservation, especially in key scenic spots, and the soil should be kept moist frequently.

Red magnolia pruning:

The pruning period should be after flowering and before sprouting. Diseased, over-dense, redundant, juxtaposed and futile branches should be cut off, and sprouting should be removed at any time at ordinary times. When pruning, the medium and short branches shorter than 15 cm are generally not cut, the long branches are cut to 12 cm ~ 15 cm, the cut mouth should be smooth and slightly inclined, and the distance from the bud should be less than 5 mm. Due to the poor healing ability of branches and stems of Magnolia, most of them are not pruned except those which are very necessary.

Disease and pest control of Magnolia grandiflora

Underground pests such as □ root rot and grubs should be prevented at seedling stage. Longicorn beetles are harmful to stems and red spiders should be prevented at the height of summer.
