Its impossible to know what a good spray schedule would be for you as we don't know your area. Otherwise it sounds like you are more or less taking care of business. P.S. Thin fruit sooner rather than later, and be aggressive. You won't regret it.

Sarah, Stella is an outdated variety, it was the first self-fertile variety but there have been many improved varieties since then. Its taste is considered mediocre compared to other cherry varieties. I have never grown it myself so this is only based on what I have heard. Lapins is considered the "modern replacement" for Stella, it is pretty old itself by now though. Black Gold is my favorite self-fertile cherry. It has cracked for me but does better than most varieties. I don't know about Ranger peach tree. I have seen mixed reviews of Liberty and am not growing it but overall I would say its not a bad choice. You will need another variety to pollinate it. Of the disease resistant apples GoldRush seems to be the favorite for taste, then Williams Pride, then Enterprise, then Liberty. You may want to look at these other ones I mention to see if they are to your liking or for a pollinator. Scott

Lady Jane, Here's my 2 cents. I am in zone 6 on the east coast (central MA). I've grown apple, peach and cherry trees. I've never planted in the fall for fear that trees would not get established in time before the soil freezes (could just be my unfound fear). I've always planted my trees in the spring. We do have snow on the ground into April. When I order trees, I always ask a nursery to send them to me around mid April. It's easier for me to dig a hole when the soil is not so hard. (it's hard enough to dig into many rocks for each hole.) I may plant later than others recommended for zone 6 but I have never had any problem with my trees getting established.

Just curious why you would try O'Henry when there are so many wonderful varieties that have much lower chill requirement. I'm in z9, sunset zone 13, and stubbornly tried cherries.... twice. the second time I did manage to keep the tree alive for a 3rd season but they didn't produce and didn't even grow well despite every effort to give them a micro-climate that promoted chill.
