Hydrangea: leaves okayish, flowers feeble if at all...??
Hello, I am an inept but determined (novice) gardener, so please bear with me. I inherited a lovely garden with several hydrangea plants in different locations, and of different colors. My problems seem to be the same on all the plants :
very lush, dark green foliage, no flowers, or the flowers start to open but then go brownish and wilt. The flower colour is always much paler than it should be. Some of the leaves on the underside are crinkly brown around the edges and eventually dry up/fall off.
Could anybody help me clarify once and for all the basic regimen of these plants, especially how much water and how often to fertilize, what the acid/alkaline levels of the soil should be (depending on the colour I want)... the basics.
Thanks VERY MUCH,
