It’s great that you were able to give those emerging marigolds the boost they needed to make it through the season.
Outside of a few shrub varieties, marigolds are an annual flower that die back completely at the end of each season once the frost sets in. So you would not prune them, but rather remove the entire plant because it will not come back the following year.
What you likely cared for were the plants that came from the seeds from last year’s plants. If marigolds are not deadheaded, they will readily self-seed the area and plants can/will grow the following year. If you did not deadhead this year as blooms began to fade, there is a chance that seeds fell to the soil once the pods dried and opened, meaning there will hopefully be marigold plants in that same area next season. If not, you can always plant new transplants in the spring once the threat of frost has passed.
