Yes, I think it's a good idea. Many people would probably be interested in joining a project like this. It would help bring the community together because they can work on it as a group. Often, local parks and gardens are not well maintained because of a lack of funds or attention from local authorities. This is where community members can step in. Since everyone enjoys these spaces, it makes sense for everyone to help keep them nice. Simple things like picking up litter can make a big difference and are a great way to start.

I don't think people should be expected to maintain public parks and gardens. It's really the government's job to take care of these spaces. They have the resources and expertise. Besides, most people might not know the right way to maintain a park. It could end up doing more harm than good.
