You can have a true fig from trees that reach only 6 feet. Dwarf Fig trees produce sweet fruits that are good for eating fresh, canning, drying or in cookies or cakes. Where temperatures drop below 5° F, they need tub planting so the tree can be moved to shelter to both ripen the fruits and protect the top. Root is hardy anywhere, but the top will die back below 5° F. The Dwarf Fig tree may grow in zone 4 with protection and is self-fertile but will do better with 2 trees planted.
