If supports are needed, iron should be used. Wood 
frequently rots off about the time the plant has made a 
good growth. For large plants one-inch iron gas pipe is 
best, and second-hand pipe may be purchased at a low

upper end to the building (see Fig. 86). Quarter-inch 
rods with wire netting may be used for the smaller 
twining plants.
