    You can trim anywhere from 50-75 percent of the plant back. This should help encourage additional branching, making the plant fuller. You'll also want to keep it well watered during this time, which will help the plant bounce back.

    It is possible that it was Sclerotinia Head Rot. This can happen if the head of the sunflower is slightly damaged - say by winds, heavy rain or hail, which gives the fungus a route in. The fungus will not attack uninjured leaves and flowers, which is why the leaves are fine.

    Typically, if you don't see the pest, it is either slugs or rodents. Both come out late at night when most people are sleeping. These articles will help:

    With sunflowers, them bloom once and then die. Even if you bring them inside, they will not live. You can however plant new seeds that you can try growing over the winter indoors.

    You do not have to remove the spent blooms. Once the plant flowers, removing the blooms will not result in new blooms (which does happen with some other plants). Many people like to leave sunflower heads on teh plant so that the birds can eat the seeds in the winter. But you can cut them off and harvest the seeds so that you can grow more in the future.
