Rancher Hicks, I have about 1/4 acre of fruit trees and my son has just over 1/2 an acre of fruit trees. They aren't much work. I do all the care for both orchards.
Both of us have irrigation lines laid out so to water, all it involves is turning the spigot on. Neither one of us have any weeding to do. I've got mulch in my fruit tree area and my son has ducks and geese in with his trees. They eat all the weeds and all the bugs. However, my son does have wire rings around each tree because the geese will chew the bark.
After the blossoms are off, I spray every 3 weeks up until the end of August. I only spray the apple trees and I use a hose end sprayer that gets the job done fast.
Of course, if you get a good crop, then the work begins: harvesting, canning, drying, cooking. There are late apples that will store fresh all winter if you keep them in a cool place and don't let them get frozen.
With dwarf trees, you never need a ladder. I've got some pretty big semi-dwarf trees and I never use a ladder, either, except to pick cherries. I can reach a lot of the fruit and I've got a fruit picker, which is a little basket mounted on the long pole. It works really well.
