I am in dire need of some advice. I have three Fiesta Forsythia plants and they are truly one of my favorites in the garden. This past year they took a lot of abuse from lack of my attention and the overcrowding of invasive plants. I just finished uncovering them and found them in pitiful (read shameful) condition. What I found is long stringy stems with tiny leaves. I am sick. What can I do to save them and return them to their once gorgeous condition??? Can I cut them way down to encourage them to grow strong? Or, should I bite the bullet and put them out of their misery? I greatly appreciate any advice given.
Thanks so much,
