Is Guangzhou suitable for planting Magnolia grandiflora? Will it bloom?
Of course. I like warm, humid and sunny environment, and I am cold-resistant, but I am not tolerant of drought and salinity, and I am afraid of flooding. I want fertile sandy loam with good drainage. Magnolia grandiflora cannot grow in calcareous and chalky soil; The branches are weak and need to be planted in a slightly shady place; Good wind resistance and strong tolerance to air pollution; Resist The short-term low temperature of 20℃ likes warmth and humidity, likes light, and is not resistant to stagnant water and drought. Its root system is developed, its tiller germination ability is strong, and it is resistant to pruning and shaping, but its healing ability is poor. After pruning, it should be coated with sulfur powder for anticorrosion. The fleshy root is not easy to transplant for fear of injury. If transplanting is needed, it should be done after defoliation in late autumn or flowering in late spring, when the climate is mild and humid. Magnolia grandiflora should be pruned regularly to remove diseased branches, residual branches and dead branches in time, otherwise the tree will develop into a shrub, which is not conducive to the growth of flower buds.
