When to Remove the Straw Rope from the Trunk of a Newly Planted Large Magnolia denudata Tree and Whether Removing It in Summer Affects Survival

    At this time, under no circumstances should the straw rope wrapped around the trunk of a newly planted large Magnolia denudata tree be removed, otherwise its survival rate will be severely affected. For large Magnolia denudata trees planted in early spring, by July to August, even though dense foliage has already grown, this does not mean they have completely survived; in a sense, they are still in a state of "false survival," and careful, detailed management must continue patiently. Only after leaf drop in November can it be proven that they have completely survived. If the rope is hastily loosened and removed in summer, although the trunk will look neat and attractive, the bark of the trunk that was suddenly exposed from inside the straw rope binding will be subjected to the summer's blazing sun, intense light, and high temperatures. The temperature on the bark surface will be 10-15°C or more higher than when it was wrapped in rope, and moreover, being directly exposed to the scorching sun, the relative air temperature at the bark surface will inevitably drop sharply. High temperature, dryness, and intense light will severely damage the bark. In addition to possibly causing large areas of bark damage, it is very likely to endanger the safe passage of the Magnolia denudata plant through the summer. This phenomenon of transplanted trees dying due to premature rope removal is commonly seen in urban greening tree planting. One must never rush things just for the sake of a neat-looking trunk.
