-ing is interchangeable here in Australia with to be -ed e.g. "the roses need pruning" vs "the roses need to be pruned" Yet there's a formality typical in passive aggressive notes of using the 'to be -ed' syntax. Further, one only need apply 'to be' once with several actions "dishes need to be washed, dried and put away". Maybe -ed emphasizes the completed state vs continuous -ing focusing on the event of doing the action. e.g. opening sparkling wine with a popping cork is part of the occasion.
