The author is about a planting support structure, which is mainly provided with a reinforcing material in the pipe hole of the metal pipe, and a waterproof cover is respectively sleeved at the two ends of the metal pipe, and the metal pipe is adjacent to the bottom end thereof. The sleeve is provided with a rustproof sleeve, thereby, when used, the metal sleeve is provided with a rustproof sleeve inserted into the soil to prevent moisture erosion in the soil, and when a typhoon or strong wind blows, The reinforcing material provided in the metal pipe can effectively improve the bending strength of the metal pipe to avoid the large bending and breaking of the metal pipe, and accordingly, the plant provides a good supporting effect for plants such as banana trees.本創作係有關於一種植栽支撐結構，係主要於金屬管其管孔內設置有補強材，並於金屬管二端分別套接設有防水蓋，又使金屬管與其底端相鄰一段處套接有防鏽管套，藉此，當使用實施時，係將金屬管套設有防鏽管套一段插入土壤中，以防止土壤中水分侵蝕，另當颱風或強風等吹襲時，藉由金屬管內所設補強材即可有效提高金屬管的抗彎強度，以避免金屬管大幅度彎曲折斷情形，據此，俾提供香蕉樹等植物良好支撐效果。
