There is no reason that multiple cultivars of apples should be avoided which 
gives the ability to pick over a wider period of time. A crew can work on the 
field over a month's period rather than a week (for peak maturity). Likewise 
there are dwarfing rootstocks for pears, apricots, cherries, and peaches so 
that mixed plantings can be done.

The real problem that I know of is that the orchard requires very precise 
applications of water. The dwarfing works by restricting water uptake so the 
trees can't stand running short of water. 

Because of the continual pruning, there is the potential of lots of composted 
wood chips which can go back under the trees. This will help maintain soil 
moisture. 

There are new cultivars that don't use dwarfing rootstocks but are genetically 
dwarfed. Check them out.

APPLE BABE GENETIC DWARF APPLE Crisp, sweet, red apple - 
 excellent quality even in hot inland climates. Glossy, russett-free skin. 
 Heavy bearing 8-10 ft compact tree. August. 700 hours. Pollinated by 
 Garden Delicious or other apple. (Zaiger) 
 GARDEN DELICIOUS GENETIC DWARF APPLE Sweet, crisp, superb 
 flavor, even in hot climates. Greenish-yellow with red blush to full red. 
 Dessert/cook, good keeper. September. 8-10 ft. tree, smaller with pruning. 
 600 hours. Self-fruitful. 
 NORTHPOLETM COLUMNAR APPLE Large, red-skinned 
 McIntosh-type fruit is crisp, juicy and aromatic. Attractive, distinctive, 
 narrow-growing (columnar) tree, grows to about ten feet. Trees topped for 
 height control develop upright side limbs. Easily adapted to container 
 growing. Estimated chilling requirement 800 hours. Pollinated by Scarlet 
 SentinelTM or other apple varieties. 
 SCARLET SENTINELTM COLUMNAR APPLE Dense clusters of white 
 blossoms followed by large, delicious, red-blushed, greenish-yellow fruit. 
 Attractive, distinctive, narrow-growing (columnar) tree, grows to about ten 
 feet. Trees topped for height control develop upright side limbs. Easily 
 adapted to container growing. Estimated chilling requirement 800 hours. 
 Pollinated by NorthpoleTM or other apple varieties.
