Do you mean that they have completely disappeared? If that's the case, there's nothing you can do. But if they're just wilted, water them with a watering can and they'll be back to normal the next day.

You could also change your town ordinance to beautiful ordinance. That way flowers won't wilt. I use this ordinance because I have a lot of flowers, even though it is a bit annoying to not have shops open later.
