Pears and Apple trees

At 6' tall the trees would only be 2-3 years old. Way to young to expect anything. Probably won't see much more then a couple apples for a few more years. I have a semi dwarf 5 in 1 apple tree that just this year will provide all 5 types, and it's over 7 years old and about 20' tall. I've gotten 2 types off it the last couple of years, mostly Granny Smith and Macintosh.

Just had the June drop and about 1/4 of the apples fell. Branches are loaded and one broke from all the weight.

Pears start sooner in age but it still takes a couple of years before you'll see much of anything. I have two, a Bartlett and Anjou, with the former being a real heavy producer. Last year, at 5 years old I got over 7 bushels off of it. The Anjou only about 1 bushel, though it's a year younger. Maybe 2 bushels this year off it and about 10 from the Bartlett.

I spent a little time looking on the internet and it seems your area may be getting close to where some apples may not get enough chill hours (depending on how warm the winter may be). Your area is 7b, 8a for winter hardiness so, in that respect most apple trees are OK.

I've included a few links on apple trees, cross pollination and the like;

Just a couple of questions since I have no idea about most of the varieties you listed. Did you explain to the nursery where you live? The difference between northern and central Georgia could have an effect on what grows fruit. The nursery should have a better idea of what suits your purposes then many of us here.

Besides the macro climate there also the micro climate of your area. As an example, I live on the western side of the Delaware River and the ground slopes towards the river. So with the 'hill' west of me I'm fairly well protected from the cold winter winds. Now on the other side of the river it gets much more snow, picking up those 'lake effect' snows from the air being warmer over the river. But it's actually warmer on that side of the river, picking up some heat from the warm water (compared to the cold ground). Also my land is mostly heavy clay, while the other side of the river is sandy loam. It's also noticeable during the spring and summer that the other side of the river gets more rain and thunderstorms, just because of the air mass being a different temperature on the river. So, although the distance between these two places is less then a mile, and visible to each other, the climates are distinctly different.

There's two things of concern with many fruit trees. Plant hardiness and chill hours. The tree has to be able to handle the winters without freezing to death as well as have a minimum amount of chill hours for flowering to occur.

The biggest thing about pollinators is that they flower at the same time. Some are early, others late and they may not be flowering at the same time. Even then there's no guarantee that they'll actually produce fruit every year.

I've got one multi grafted apple tree, with 5 different kinds of apples on it and I've yet to get all 5 varieties, though they all seem to be flowering. This is one of my oldest fruit trees at 8-9 years old. Most years I get two to three varieties but never all 5. Last year I thought I'd get all 5 but alas the Red Delicious still hasn't produced a single apple.

Be aware that some trees just take longer to produce. I've got several pear, peach and plum trees and they started producing fruit at a much earlier age then the apple trees.
