How come my hydrangea has not bloomed? I bought it 3 years ago - of
course it was in bloom then - hasn't bloomed since.

Do you cut it back every winter? If so you are cutting off the
following years flowers. It blooms on old wood.

This means that if the stems get killed to the ground over the winter
(which is usually the case in northern areas) the plant will not bloom
that season. It will send up new stems which look good but will not
flower. Next winter you might consider treating the plant like a rose
bush and cover it after it goes dormant to protect the old stems which
should result in flowers for next season.
