Can You Grow Fruit Trees in Pots?
You don’t need a sprawling orchard in your backyard to grow fragrant, delicious fruit. You just need plenty of sun and ample indoor space, plus some patience. Laurelynn Martin and Byron Martin, authors of Growing Tasty Tropical Plants in Any Home, Anywhere and co-owners of Logee’s Plants for Home and Garden in Danielson, Connecticut, offer some expert tips to grow indoor fruit trees.
Indoor Fruit Trees Need Lots of Light
Most fruit trees—even the more shade-tolerant ones—need at least six to eight hours of direct sunlight per day to produce a crop. A large, unobstructed southern- or western-facing window is an ideal spot for a potted fruit tree. If you don’t have enough natural light, look into grow lights.

Give Indoor Fruit Trees Room to Grow
When planted in the ground, fruit tree roots spread out to find water and nutrients. Most potted plants do fine in plastic containers, notes Byron. Just make sure your pot is large enough to allow for growth and has drainage holes, as water buildup can cause root rot.
“Plants that are susceptible to root diseases are best grown in terra cotta pots,” Byron adds.
Fill containers with standard potting soil mix and add plant-specific fertilizer regularly. Psst—here’s our guide to plant fertilizer 101.
Watering and Pruning Indoor Fruit Trees
Water fruit trees when the soil becomes dry on the surface, making sure to saturate the potting mix. If possible, keep your home’s humidity around 50% for best results.
Byron also suggests pruning to maintain the trees’ size and form while being careful to not cut off the flowering growth.

Pick the Right Types of Fruit Trees to Grow Indoors
Larger temperate fruiting trees, such as apple, cherry, pear and plum, belong outside, says Byron. They require chilling time and plenty of height and room to bear fruit. Instead, he recommends selecting tropical or subtropical fruiting plants that’ll be happy indoors.
Byron says citrus trees, such as kumquats, are great plants for indoor gardening because they produce fruit very early in their growth.

Arabica Coffee Plant
“The cherries, or coffee beans, are green before they ripen to red,” she says. “Then you can shuck off the fleshy pulp and get the raw coffee beans inside.”
She suggests storing the beans in the freezer until you have collected enough to roast for a cup of coffee.
Lemon Guava Trees
Lemon guava (Psidium littorale) is a tropical plant that does quite well indoors.
“It tolerates the dry air and lower light found in homes, has shiny leaves and begins to fruit at 3 feet,” Laurelynn says.
Wait for guava to turn completely yellow before enjoying its sweet flavor.
Originally from South America, a tree tomato plant produces egg-shaped red fruit that has a custard-like texture. The plant, which is sometimes called tamarillo, will fruit from late summer through the winter.
It does well indoors and is best grown from a cutting, according to Laurelynn, because it’ll flower and produce fruit when the plant is smaller.

When to Take Your Fruit Trees in Pots Outside
Once danger of frost has passed in your area, your fruit trees can enjoy the outdoors and the beneficial insects that will pollinate them. Here’s how to find the first and last frost dates for your area.
Byron points out that it’s important to move the plants slowly. Put them in shade or partial shade first so the leaves don’t burn, and let them harden off for a few days.
