I too am really interested in how this turned out. I planted 9 forsythia in part shade along a tree line/fence we share w the neighbor. Their place is kind of trashy so I wanted something large that would screen it off in the summer. Plus it is kinda a ways from the house so something w some color that would pop. Right now it gets sun most of the afternoon. Shaded mornings on the east side. But I did plant some maples and fruit trees along the area and eventually those will shade the are in the afternoon. I know that will be 10 years from now, so I am just going to enjoy for the time being. Eventually, they may not bloom much due to lack of sun, but I will be happy at that point if they just are large and green as a privacy hedge. I do not plan on pruning them- only to shape them a little, cut off dead stuff, nothing serious. My neighbor on the other side of me has some planted as a hedge and she shears them off formal. I think they look kind of silly that way and they hardly bloom for her-but they are thick, green, They are also planted in more shade than sun. And also under some trees, hickory mostly.
