can you tell me what kind of plant this is and what I should do for winter preparation? Cut it back?

Asked October 31, 2018, 4:24 PM EDT

I live in Woodbury. A friend have me two of these plants two years ago. Now it is huge, this is the first year it bloomed. It is very tall, at least 3 feet. Wondering if I can cut it back so it will be not so tall (tipping over) instead if it would become fuller? Thank you for your help.

It's a New England aster:

You can reduce the height and increase bushiness by pinching back the plant in mid-summer. But even then, you may have to stake it, especially if the site is not full-sun.

You can (although you don't have to) cut it down to the ground after the blooms are finished, but that won't affect its height next year.
