A trick for encouraging growth in iris
I just use my fingers and scrape away some of the leaf litter, rocks and any other stuff that is around the base of each plant. Yes, it's OK if you can actually see the top of the bulb. When you do the scraping, you make a little swale that will hold water better. Get a large watering can with some plant food mixed in (I use Miracle Grow, but they're all the same) and water. Then do it again, and again. Iris love water, and for some strange reason, they do better with their roots exposed. I don't know why, but they do. Iris that are planted too deep don't do as well. I found this out by accident, because, well, I got sloppy one time in my planting.
