Guidance on plant spacing

I have a question on how far apart you space plants. I'm planning a new border and want some general advice.

Most plants come with advice on their spread and how far apart to plant. If it's a permanent fixture, like a tree or shrub, I probably would stick to the guidance. But what about annual bedding plants? I ask this as I've planted some Calendula. It said to space them 30cm apart, but now they look like individual plants and not like the drift that I hoped. Is it with annuals you can place much closer together than advised?

    Yes, you can certainly plant them closer together.  Municipal displays of "carpet bedding" have the individual plants just a few inches apart.  The closer they are, the more you'll need to water and feed them though, as they will compete with each other.

    Since 2019 I've lived in east Clare, in the west of Ireland.
