If you get abundant flowers at the same time on both trees, you should be setting fruit. Assuming there are bees around to cross-pollinate. If the blooming times don't overlap, you may need another peach just for that purpose. It's pretty easy to fertilize them. Just sprinkle a handfull of osmacote around each one out to the dripline. One treatment lasts all season. I wouldn't bother spraying until you see fruits or insect damage. Of course the leaves can be damaged by both insects and diseases, and using a combination fruit tree spray (insecticide/fungicide) every two weeks is common practice. As for drainage, 10 hours is not that bad, though well-drained soil is recommended for all fruit trees. Pears tolerate wet feet better than most. 72 hours submerged roots will kill peach and plum trees. If the trees are still small, you could dig them up and raise the bed. But likely not needed, IMO. It's normal for some peach leaves to yellow and fall off in the Fall. Also you may need to remove up to 1/3 of the branches each year once you see normal growth.

I haven't grown peaches but went to pick peaches Peaches of Pasco in Pasco county this year and the peaches were absolutely amazing! There are some interviews with the owner on-line and he references the variety "UFOne" as one of the ones that he grows and sells (150 chill units). I pasted the description of this type and "UFSun" below. When at the place, I picked a large white, non-melting variety and a yellow "melter" variety. Both were so wonderful. 'UFOne' (U.S. Patent PP21,607) Peach Variety Description: 'UFOne' is a peach variety with a low winter chilling requirement of approximately 150 chill units (cu). Trees of 'UFOne' are of medium size and moderately vigorous with a semi-spreading growth habit. Trees of 'UFOne' are self-fertile and regularly bear heavy annual crops of early season fruit which are medium large for its mid-early ripening season. Fruit of 'UFOne' are very firm with a yellow, non-melting flesh which are semi-clingstone. Fruit of 'UFOne' are uniform and substantially symmetrical in shape and have an attractive light red color over 40% of skin. Fruit of 'UFOne' which is exposed to sunlight has a higher degree of enhanced red skin. The fruit of 'UFOne' ripens about 95 days from full bloom, which is approximately eight (8) days after that of 'UFBeauty' peach (U.S. Patent PP14,784) in early May in Gainesville, Florida.

Depending on how much time & effort your husband is willing to put into fruit trees, my own recommendations are to plant pears - Asians or Europeans. They're relatively low-care; beyond a minor amount of pruning/training, they require almost nothing else - I've never sprayed my pears, and they reward me with virtually perfect fruits every year. Apples & stonefruits(peaches/plums, etc.) are a very different situation. Insect & disease problems are rampant, and require frequent spraying, if you want to end up with any decent fruits - and the regular late spring frosts frequently nuke the blossoms/young fruit on most of the stonefruits - if you get a decent crop of peaches/plums one or two years out of five, you've done well. You might also want to consider some persimmons - IN is the persimmon capitol of the world, you know. Another care-free, no-spray fruit.

Korean Giant ripen around early-mid Oct in zone 6 a. It probably will ripe around mid to late Oct for you. Should not be too late. Very good and productive tree, worth a try. Not sure why the northern ridge nursery does not carry northern peach varieties. Flordaking as the name implies is a southern peach!!! Of the 4 that nursery carry, I would choose Red Haven or Elberta over the other two. You can't go wrong with either. They are good peaches. I do not know if they will produce peaches well in your zone. They may if your winter is not too harsh on some years. When you buy on line, it does not matter where the nurseries are located as long as they can ship to you. Many nurseries are in WA. Those in warmer areas may ship bare root trees to you by March. That's OK, just keep them in the box, in a dark place, make sure the roots are moist (not wet), they will keep until April when you can dig the ground. Otherwise, you can tell them to ship trees to you when you can work the ground. Burntridge Nursery is good. Autumnridge is bad. Whenever you come across any on line nursery, just google "Scoop on + the name of the nursery", info about that nursery will show up. It's done by a garden watchdog, Dave's Garden. Avoid the one with a lot of negatives. Nurseries like Cummins, Adam County Nursery, Grandpa's Orchard, Burntridge, One Green World, Raintree, Vaughn, Stark's Brothers are reputable.
