from gardener Jerad Bryant.

If you love apple pie and caramel apples, ‘Granny Smith’ is the variety to grow at home. The fresh-picked apples taste delicious and are hard to compare to store-bought ones. Grocery stores sell apples before they ripen, and they lack the sugar content that makes homegrown produce preferable.

Of all the apple varieties, ‘Granny Smith’ is iconic for its green fruit and tart flavor. If you’ve eaten a green apple in your life, chances are you ate a ‘Granny Smith.’ From its humble beginnings in an Australian homesteader’s orchard, this tree now grows in orchards throughout the northern and southern hemispheres, from Australia to the United States.

Have you heard that fruit growing is a challenge? There are chill hours, ripening seasons, and pollination buddies to consider. Fear not, as we’ll learn everything there is to know about growing a thriving ‘Granny Smith’ tree below.
What are ‘Granny Smith’ Apples?

‘Granny Smith’ is an apple tree that produces bright green, tangy, and juicy apples. Unlike most other varieties, the fruits are ripe when they’re green. They make excellent caramel apples, applesauce, and other prepared apple dishes. When cooked, the zesty flavor complements the sugar content.

Each September, they ripen on my backyard tree. Right before the tree’s leaves change color, I pick the green apples to make apple jam. If you like sharp-tasting apples, they are also excellent fresh. Just know you might pucker up a bit after eating one!

Apple trees not only create delicious produce, but they also form graceful statures in maturity. They sprout sweet-smelling flowers that are a boon for pollinators, as the bees and bugs in your area benefit from the surplus of apple nectar.

Native Area
For more than 100 years, apple breeders have crossed and bred species to produce the hybrids we know and love today. Species like Malus sylvestris from Europe and Malus coronaria from America shared pollen and created new hybrids. To make classification easy, most cultivated apple species are now considered Malus domestica.

Apples are native to central Asia and Afghanistan, although they now grow in Australia, the Americas, Europe, and Asia. They are a worldwide fruit phenomenon beloved by many different cultures. Each variety has growing preferences, and with hundreds of options, there is surely an apple that will thrive in your garden.

The ‘Granny Smith’ parent tree originally grew in Australia at the hands of Maria Ann Smith. It prefers a long and hot growing season, and ripens later than most apples. In the United States, the West, the East Coast, and areas of the South have optimal conditions for growing this variety.

Characteristics
I value my ‘Granny Smith’ tree for its ornamental beauty and its bountiful fruit production. It is deciduous, and the leaves turn a buttery yellow each fall. In the spring, it sprouts pinkish-white blossoms that bees and pollinators love.

This variety grows to 12 feet tall as a dwarf, and 16 as a semi-dwarf. Standard ‘Granny Smith’ trees can grow over 20 feet tall! Dwarfs make excellent espaliers. Semi-dwarfs and standards spread to be anywhere from 15 to 20 feet wide.

‘Granny Smith’ apples ripen to a distinctive glossy green color. Tiny white spots speckle over the bright green skin. Pick them in the late fall after they’ve swelled to a good size. If left on the tree, the apples may turn yellowish-green and lose their tang.

Dwarf trees may need additional staking when young and are more susceptible to storm damage than semi-dwarfs and standards. Choose the right type for your garden size, and you’ll treasure your tree for decades to come.

While ‘Granny Smith’ apple trees are self-pollinating, apples benefit from another pollinator tree nearby for maximum fruit production.

Propagation
How do you best propagate an apple variety? To achieve the same genetics as your parent tree, you’ll need to take cuttings from a ‘Granny Smith.’

Apples grow from seed in the wild and are hybrids of their two parent trees. Growing apples from seed is a fun activity, but not a reliable means for fruit production.

I am not discouraging you from growing apples from seed! Just know that your daughter tree will not look like ‘Granny Smith’, and its apples may look and taste completely different.
