Fertilization technique of Magnolia mandshurica

Red magnolia flower sowing seedlings unearthed 1-2 years after the midsummer season, need proper shading, after winter, should also be cold protection in the northern region.

Transplanting does not hurt the root system, big seedling flower planting should take soil balls, dig large holes, deep fertilization, before planting, fully mature organic fertilizer should be applied as base fertilizer. Proper deep planting can inhibit tillering and is beneficial to growth. After planting, seal the soil and press it, and pour enough water in time. It is better to transplant before sprouting, or before flowers are just shedding, or before spreading leaves.

Summer is the growing season of Magnolia. Magnolia likes fertilizer. In addition to paying attention to base fertilizer, acid soil should apply more phosphate fertilizer appropriately. Topdressing before and after flowering is particularly important. Fertilization should seize the two key opportunities of February before flowering and May after anthesis and apply nitrogen, phosphorus and potassium compound fertilizer once every ten days or so.

The former makes buds dilate 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.
