Tiger Lily Question

Tiger Lily Question

Hello everyone! I have a tiger lily garden in the front of my house. This is only my second summer in the house so last year I just let things go to see what would come up. In the fall I raked out the garden, everything seemed to come up nicely this spring, but now I hardly have blooms. Last year they were out of hand and this year it's a few here and there. I know the women that lived in our house before was not much of gardener and I'm sure I'm making a bigger effort with the gardens. I guess is what makes this so frustrating! I'm diligent about watering and caring for them, but I have no idea what happened. Any suggestions? Perhaps I shouldn't have raked out the garden in the fall? I'm pretty bummed about this and I hope to not make the same mistake twice. Thanks for your help! Here are my garden photos. As you can tell I tend to take lots of them. :o) Thanks again!
