Abstract: Method of manufacture of foam coated rod-like elements particularly for supporting pot-grown plants in general comprising the step of arranging a plurality of elongated tubular members of plastic material in spaced parallel relationship to each other into a tank and casting synthetic foam forming chemicals into the tank. The foam forming chemicals are caused to expand within the tank up to a level higher than the uppermost tubular member. The tubular members are thereby embedded into the foam. After hardening of the foam from the formed foam block foam coated rod-like elements are cut out each containing embedded therein one tubular member.
