Just got my catalog from Burgess Seed and Plant CO. I am considering ordering their "Postage Stamp" Orchard. 1 Dwarf Yellow Apple, 1 Dwarf Red Delicious, 1 Dwarf Elberta Peach, 1 Dwarf Kieffer PEar, 1 Dwarf North Star Cherry, 1 Dwarf Nectarine. I've neevr had an orchard before - any suggestions? Are these good combinations? Should I do something different? I am in Indiana. They claim that no extra pollination is needed, and that you can plant this in a 10 x 20 foot area. I have about a 30 x 50 ft available for the orchard. Any suggestions for a beginner???? Thanks!
