I think each person should do the pattern or design that works out best to meet their needs..
On our property I am old and my husband is disabled, so I'm going with a lot of dwarf trees although some are full standard size..and a few are semi dwarf..
also I can't really climb a ladder with my partially disabled body (hip replacement and a lot of pain) so I have mine arranged to suit my health and my needs.
I have hedgerows and suntraps around the main food forest garden to provide a lot of different needs including fruit as they are made of wild plums, hazelnuts, serviceberries, mulberries, hawthorn, buffaloberry, red, yellow and black raspberries, blue berries and black berries on North West and south sides and on the east where we get the most sun I have asparagus and perennial crops with a mountain
ash and baby paw paw
in the center of this are 3 dwarf apples, 3 dwarf pears, 3 dwarf cherries and a lot of perennial food crops as well as some annuals in the summer.
I plan to move some stone fruits to this area as well..this summer from where they are
I also have fruit crops planted around the house on the slopes going down from the house and I have other
apple trees in various places on the property and other nut trees, 3 kinds of walnut, almond, chestnut, etc.
these are the plants we feel will meet our needs as we age more..without requirig a lot of replanting or climbing to harvest..i also have grapes and other vines and plan to put in more..I hope this is helpful
