For the first few years I was gardening, I lamented in the spring that my tulips didn't bloom well. A lot of green but sparse blooms. After hearing advice that tulips need bone meal after they bloom, I decided to get off my butt and do something about it.
The problem is that by the time my tulips are done, I can't get at all of them to dig in bone meal unless I crawl in under growing perennials. What I did discover is that it doesn't have to be a big job. I grab the bucket of bone meal and a scoop, and simply throw scoopfuls onto every place where there's tulips.
Finally I'm getting tulips back that haven't bloomed in years... which, of course, is going to make me want to plant more in the fall.
