Hi, Well you don't say how old your bulbs are. Daffodils, as they get older and more crowded do tend to bloom less and less. The problem won't be squirrels because daffodils taste bad so deer, rabbits and squirrels leave them alone. It sounds to me like your bulbs might be too crowded. You can go to the trouble of digging them up next fall and moving them, but even then, it will take some time for them to recover. I suggest you just buy new bulbs next fall and start over. I also see here in the keyword box a question about butterfly bushes. You can trim them at most any time, but early spring is best.
