    I have heard that putting the seeds in a container (or envelope) for about a week or so will kill off the weevils. If you put them in an airtight container(glass/plastic), allow it to sit at room temp before opening. Though I personally have not tried this and can, therefore, not swear to its effectiveness, I think it would still be worth a try before dumping the seeds completely. If the seeds have already been devoured inside by the weevils, though, their viability, of course, will be zero.

    It may be worth learning how to look for and treat the weevil issue on the plants by sharing the following article with your neighbors, which will reduce the chances of infected seeds: https://www.gardeningknowhow.com/ornamental/flowers/hollyhock/controlling-hollyhock-weevils.htm

    Holly Hocks will need to be grown outdoors to meet the soil and sun requirements.
    You can start the plants indoors but in order to grow this plant, that can reach height of 9 ft tall, you will need to move outdoors.
    Here is a link with growing information.

    If they are having difficulty blooming, the soil could be lacking phosphorus, which is responsible for flowering. Adding a phosphorus rich fertilizer or bone meal to the soil should help with this.

    I thought I might have to keep them on a sunny window ledge all winter, that means the bathroom or stairs. All the rest of the rooms have ledges over radiators.

    You can cut them back during your fall cleanup, or now, if the flowers have finished for the season. Here is more info on growing these plants: https://www.gardeningknowhow.com/ornamental/flowers/hollyhock/tips-on-hollyhocks-growing-hollyhocks-successfully.htm

    I would inspect your hollyhock for an insect infestation, particularly for thrips. More information on thrips can be found here: https://www.gardeningknowhow.com/plant-problems/pests/insects/controlling-thrips.htm

    Hollyhocks don't like to be transplanted so direct sowing is best.
    Plant out into the garden as soon as the weather is ready for any planting.
