Abstract: The invention relates to a device (1) for forcing flower bulbs (11), which device (1) comprises at least one plate (4) or plate-like body provided with one or more holes (6), into which a flower bulb (11) can be placed. The edge (10) of at least one of the holes (6), but preferably of all holes (6) is elastic and/or flexible to such an extent that a flower bulb (11) can be clampingly received in said hole (6). Preferably, at least part of the edge (10) of at least some of the holes (6) formed by a flexible insert member, which preferably includes a number of flexible elements, such as teeth or fingers (15), which extend in radial direction, seen in top view.
