the invention relates to a method for propping up stems (shoots), carrying leaves, or even fruit, of annual plants or perennial plants or bushes, as well as the props for implementing it. It is characterised in that, instead of pushing the plant to the side of the prop, a tubular cage 7 having a distinctly wider cross-section than the cross-section of the stem (shoot) is placed around the plant 1 so that this stem (shoot) can grow freely inside it and having transverse bars in order to offer thereby a possible support on the said bars for fruit-bearing laterals. Application to the crop-growing equipment industry. <IMAGE>
