A stake support for plants comprises a tubular support upstanding from a base on which, in use, a grow-bag is positioned with the tubular stake support penetrating and passing through the lower and upper surfaces of the grow-bag to form openings in the bag surfaces. The surface of the base which surrounds the lower end of the tubular stake support is raised to lift the opening formed in the undersurface of the grow-bag to a height which is above the level of the base when a grow-bag is supported thereon. In cross section, the tubular stake support is preferably circular. The raised base surface is preferably of semi-spherical shape.
