Can Forsythia plants be reproduced--cut the branches, dig ups roots?
My mother-in-law asked my husband if she could cut my forsynthia shoots and reproduce them at home. I think it was a waste of time. Fortunately you cannot tell the plant was attacked.
How long do forsythia bushes remain in bloom each year in New York?
They normally bloom from 2-4 weeks. It really depends on the weather.

I have just finished reading your article on forsythia pruning, but one question remained unanswered for me. The branches on my forsythia are rounded upwards, but I have two or three really straight shoots growing mainly in the middle. Should I cut those right to the trunk or just shorten them? While my shrub is in bloom right now those shoots already have leaf buds on them.
I would wait until the shrub has finished flowering and then you can cut them back by about a third.
We pruned (radically) our very old forsythia bushes that hadn't been tended to for years. Around the base of the bushes are many branches on the ground, now sprouting leaves, etc. What is this called and how do we get rid of, or tend these? Will they grow up and become more bushes?
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.
I have many forsythia shrubs. They are very old. They bloom lovely year after year. I just noticed that all of a sudden I have no leaves. They are curled and the tree looks dead, as though someone had sprayed it. The ones next to it are fine. What is wrong?
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.
Why has my forsythia bush stopped blooming?
If it did not bloom this year, it is most likely lacking phosphorus. Add some phosphorus to the soil.
