Mom & Dad said that they didn't want fruit trees because of the investment in time that it takes before they bear fruit.
When I was a young guy, I bought a half dozen fruit trees and planted them on my place. Within a few years, I moved . . . So, I dug up my trees and moved them into Mom & Dad's backyard

. I guess I must have had an okay to do that. Investment in time? They lived in that house for another 35 years!
I think 1 dwarf apple tree might have died of old age

. Anyway. The peaches must have been a mistake. One had bark borers and died. I replaced it - that 1 died. Another replacement/another death.
My French petite prune was damaged and weakened until it also had to be taken out after about 15 years but it had done so well that I put another in and it also did fantastically. Another 20 years and it is probably still doing well! The only thing that tree needed is a spraying with insecticidal soap every year to give the tree a break from the aphids & leaf-roller caterpillars. Tons of fruit!
Those red balls with Tanglefoot on them was what trapped the worms that got in the apples. They benefited from the soap spray some years, too. One apple grew so tall and still wasn't producing fruit so Dad wanted it taken out. The other 2 little trees did great until 1 began to kind of break apart, as I said. The other was a very productive little Northern Spy, the last I saw of it. Gallons & gallons of applesauce & applebutter could come off that tree each year
