Growth Rate. Dwarf apple trees only grow to be between 5 and 7 feet tall, and can take between 2 and 4 years to produce viable fruit. Semi-dwarf trees take between 3 and 6 years to reach maturity and produce viable fruit.These trees can reach over 20 feet tall.Standard apple trees will not produce fruit until they are between 6 and 10 years of age.tandard apple trees can grow to be 30 feet or taller in height, and take much longer to mature than the smaller varieties of dwarf and semi-dwarf. This long wait time, combined with the height of the tree, make standard apple trees impractical for the purposes of fruit production.
