1999 I bought a variety of dormant, grafted fruit trees. Asian pear, Stella Cherry, Chinese Apricot, Reliance Peach, & Mericrest Nectarine. Got a few Asian pear fruits for 2-3 years, then tree died. Never got cherries, tree died. Got couple years of fantastic apricots then tree died - borers. Had buried seed and now have apricot trees but no fruit yet.
The nectarine and peach bore fruit for many years. Nectarine fruit was never good. Peach is fantastic, sweet, flavorful, juicy. Buried seeds. Now I have three bearing peach trees - delicious. They were never grafted - are on own roots. The original Reliance was a dwarf, and never could stand up on its own. Had to be staked heavily. I finally took it down last year - 2015. The three children peach trees are upright and do not need staking. I will NEVER buy a grafted dwarf peach again. Of the 3 peaches I now have, the fruits are all like each other, with the Reliance Peach fruit size and taste, but one of those trees has the larger pink flowers in spring like the Mericrest Nectarine, but it bears the fuzzy peach fruit.
