The invention relates to a method for producing, without the aid of a substrate, a plurality of rooted cuttings from a plurality of unrooted cuttings, comprising the steps of: - inserting at least one unrooted
cutting (26) into each empty cavity (12, 12') of a plurality of empty cavities (12, 12') of a strip element (10, 10', 10''), the strip element (10, 10', 10'') having a longitudinal dimension (L) and a
transverse dimension (D) and being formed at least partly of biodegradable material, the strip element (10, 10', 10'') forming the plurality of empty cavities (12, 12') arranged successively one after the other in a longitudinal direction (l) of the strip element, wherein the strip element (10, 10',10'') has a first wall-forming element (20) and a second wall-forming element (22) arranged to at least partially overlap the first wall-forming element (20) in the longitudinal direction (l) and not to completely overlap the first wall-forming element (20) in a transverse direction (d) of the strip element (10, 10', 10''), wherein the first wall-forming element (20) and the second wall-forming element (22) are fixed to each other in a spacer area (14, 14') of the strip element (10, 10', 10'') longitudinally adjacent to each cavity (12, 12') to delimit the plurality of cavities (12, 12'), wherein each cavity (12, 12') has a width (W, W') along the longitudinal direction (l) of the strip element (10, 10', 10''), a depth (T) along the transverse direction (d) of the strip element (10, 10', 10''),an opening (16) on an upper side (17) facing the transverse direction (d) of the strip element (10, 10', 10'') and through which at least one unrooted
cutting (26) is inserted, and a lower side (18) opposite the upper side, wherein the lower side (18) is at least partially closed and the first wall-forming element (20) extends beyond the second wall-forming element (22) in the transverse direction (d) of the strip element on the upper side (17) of each cavity (12, 12'), and wherein the biodegradable material has a liquid
retention capacity of at least approximately 100 g of liquid per 100 g
dry weight of biodegradable material. Fig. 4 (See Figure (4)).
