2、 Fertilization method

When fertilizing magnolia, pay attention to good ways and methods. Dig out several soil ditches next to the roots. Prepare suitable fertilizer, and then pour it into the soil ditch. After putting the fertilizer, fill the soil ditch, and then pour water into it immediately, so as to release the fertilizer effect, so that the nutrients can go deep into the roots and be fully absorbed
