Ravensburger Exit- In the greenhouse

Strange things are happening in your aunt's greenhouse. Strange things are happening in your aunt's greenhouse. From one day to the next, all the vegetables have become inedible and the plants and flowers have stopped growing. The only person who can be blamed for this is the evil neighbor, who has a penchant for black magic and can conjure up evil spells and even nasty gnomes. Will you be able to free the plants from this spell, or catch this gnome or whatever? Is there any way in all this confusion, any clues...?
