Apple trees grown from seed don't grow "true to type," meaning seeds from a Pink Lady or Gala apple won't give you ... a growth inhibitor to produce super dwarf, dwarf, or semi-dwarf trees.

Each apple tree variety matures and bears fruit at a different rate. So, if you want apples fast, choose dwarf and semi-dwarf varieties of cultivars like Honeycrisp, Gala, and Granny Smith.
