The front of your house may give you a clue as to what would look best. Is it a formal design or informal? Formal means that each side of the house is the same, with the door in the middle. Many colonial styles are formal. Informal will have each side different.
With a formal design, you may want your trees in rows to complement what style your house is. With informal design, you could do either random plantings or group plantings. Look up ideas on the web to see what you like.

We live in a manufactured home, so definitely not formal or fancy. ;) I'll look up designs and see if I can sway him to my side.

You may want to consider color of bloom, too. And time of blooming. They may need to play a part in your scheme of things...have fun, and good luck for future harvest...yummy!

Rows. Because mowing is easier. If you want it to LOOK random, from front and sides, try planting at the diagonal.

But depends on how many you plant, and how far apart they are, I guess.

I planted mine in rows. Row of apples, row of peaches, row of pears, etc.
Some are dwarf and some are standard size trees so the spacing between the trees are different.
Therefore, they line up along one axis, but not the other, giving it a little bit of a random look.
Mowing along the rows is easy. I tried mowing across rows and it was haphazard; not straight at all.
Also, mowing under dwarf trees is a bit of a pain because of the low branches, I can trim the low branches off the standard trees but not so much off the dwarf trees.

Thanks for all the tips guys! These are teeny barely trees, so we've decided to put them in pots and let them grow a bit more before putting them in the ground. Still not sure how I'm placing them all, but we have time to figure it out.
