Hydrangea that has disappeared from natural growth ground

The large pine trees reseived a lot of damage of the insect in Jogasaki-coast, and many pine trees have died. The hydrangea is sunny and grows up energetically in the beginning. However, an evergreen tree greatly grows thick and it covers on that. Next, the hydrangea in the shade dies and the group in the valley is disappearing. When I entered such a valley, "Yamato-ajisai" was in blossom of a lot of flowers to be high on the head. It disappears with other hydrangeas now, and the hydrangea is slightly survived in a dim valley though it was such a state 15 years ago. H.macrophilla"Jogasaki"grew naturally bottom of a small valley that entered slightly from the pavement. I was not able to see "Jogasaki" in the darkening place last year. (June, 2004)

Place where H.macrophylla"Jogasaki" grew naturally in 1990's

This plant grew up in height that exceeded two meters in 1990's. A fat withering stalk at the center is the one when it is large. It has become a weak plant only of standing up of a thin stalk diagonally now. Similarly, it grows up by looking up in the vicinity, and the Yamato-ajisai(mophead) in blossom like the arch cannot be seen now. I trimmed a surrounding grass for this tree in 2006 and a tree branch were cut even in 2007.
