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.
Dwarf trees usually produce fruit a bit earlier than standard-size trees, as do Asian pears (Pyrus serotina L.). Once pear trees become established and begin producing fruit, you can expect a harvest within 115 to 165 days from full bloom, or three to five months. Waiting for a pear tree to begin producing fruit is an exercise in patience, but pear trees reward the grower by producing fruit for 75 years or longer.
