I do the same Lin. Especially with my hydrangia. And yes, I put the coffee grounds just right on top Rick. I don't do that with all of them though because I keep a large Rubbermade bin for all of my kitchen waste. I chop it small, take it to the bin daily and turn it regularly. Periodically I add spagnum moss, some chopped leaves (not of the oak variety), small pieces of evergreen, and worms.
Perhaps you need to 'introduce' your worms to your compost.
Postman, thank you for the tip. Because it freezes here, in the next week or so, I will spread this all on top and by spring it will just have worked itself in. I only turn the (very small) part of my garden where I put vegetables. The rest is almost all mixed perennials; I just 'scratch around' there so as not to disturb the tubers, bulbs, corms, and established roots.
