Forsythia not blooming???
For the first 5 years, the blooms of my forsythias had increased as they grew. The 5th year was with the most packed bloom. Then, the 6th year almost nothing, and now the 7th year the same. I did not trim or cut the branches, so I don't understand why they don't bloom now. I have not done anything differently from the first 5 years.
Any ideas?? Thanks
