With the information given, I'm unsure what happened to the tree, but... "Last year we started up with a tree service that does insect sprays and root injection fertilizing." Sounds like possibly a real racket! Insects aren't usually a problem for healthy trees. What kinds of insect problems have you had? As for the fertilizing, what nutrients was your soil missing? Applying the needed nutrients to the surface would probably be much more effective than the injection method. I could be wrong, but it sounds like they saw you coming!

My daylilies have looked worse this spring than any other year. I think many got frosted a few times. The dormants are okay but the evs and Sevs have looked terrible. Some of the leaves were just hanging there limp. I don't think it has been spring sickness on most of them. I always get a few plants that have it but they look different than this. They are growing through it but I have cut many yellow ends off and am going to do more. I always seem to have some leaf streak and have heard it can infect already damaged leaves. This year it is going to be terrible. I have also lost the centre of a few clumps that are fairly close to each other. Do moles or voles do this? I always see their tracks when the snow melts but have never had an issue with them in my daylilies. They put many holes in my lawn but I just look at it as aeration! These clumps look like all of the centre fans just disappeared.

its a recent transplant.. if it were in my yard.. and it simply lived thru winter .... i would be high 5'ing you ... lower your expectations a bit .... and be happy its still green and growing.. lol ... i often wonder if the chemical insult of a remedy.. might actually harm a recent transplant ... so i often.. just go the watering route for transplants ... no fert ... in case you were wondering .. just deep watering and near drying in between .. insert finger thru mulch.. to check ... ken

No, PM will not make you sick. There are a zillion particles that come in through window screens and those who suffer from severe allergies usually keep the windows closed. If you've never been bothered yet, PM won't give you any problem.
