Pruning 'Summer Crush' Hydrangea in Late Summer or Early Fall

Hydrangea 'Summer Crush' in June... in September Pruning can be a complicated project, especially when it comes to hydrangeas (I can think of one more plant that causes pruning headaches - clematis). That said, if you grow many hydrangeas, especially different types, once you get the hang of it, it begins to come naturally. I used to rarely prune my hydrangeas because I had more space. Now, with a smaller garden, I'm finding that some are getting too large for comfort. Case in point, 'Summer Crush'. It is actually not a huge hydrangea, but it does get larger than advertised - about 5 feet in my garden (the tag said 3-4').

Tom McCall Waterfront Park, Portland, Oregon

The Tom McCall Waterfront Park (named for a former Oregon governor), stretches along the western side of the Willamette River. At the southern tip is a harbor, restaurants (we ate at a good seafood restaurant here) and an amazing garden filled with ornamental grasses and other plants. This is where these photographs were taken.

If you head north, you approach a walking area (you can see it in the bottom photograph, next to the seafood restaurant), that extends all the way up to Naito Parkway and the downtown area where our condo was located. This area is popular with joggers, bikers, people walking their pets, etc. The space was once a freeway. It was torn down in 1975 and this park was created. It opened to the public in 1978.
