    They normally bloom from 2-4 weeks. It really depends on the weather.

    I would wait until the shrub has finished flowering and then you can cut them back by about a third.

    Those are suckers. When you radically prune a shrub, they are common. You can dig them up and plant them elsewhere or let them grow and further fill out the current shrub.

    Since few problems occur with forsythias, it could be that you need to prune them. This would be especially true for older shrubs. Here is an article that you may find helpful: https://www.gardeningknowhow.com/ornamental/shrubs/forsythia/forsythia-pruning.htm

    If after pruning, you are still exhibiting problems or notice any pests that may be lurking deep within the foliage or branches, further steps may need to be taken.

    If it did not bloom this year, it is most likely lacking phosphorus. Add some phosphorus to the soil.
