I agree, a garden design program would really be based on visualisation technology (2D or 3D) while a planner would be more like a database/calendar. Two very different skillsets required and unlikely to be created by single programmer so would need to be written by a team. Market research has probably made it untenable which is why so few are around. I've often looked for something like this over the past ten years and have been disappointed. I think you would be better finding two separate applications or doing the planning yourself in a similar way to the method I suggested, but you then need quite well developed Microsoft Office skills. You can still download google sketchup which could be used for design.
