Patience is needed to grow citrus indoors
When Heather Rhoades bought her first indoor orange tree nearly 20 years ago, she had to order it from a specialty online retailer. Now, it’s not uncommon to find citrus trees at local gardening centres or big box stores, said Rhoades, owner of Gardening Know How, an online resource based in Bedford, Ohio.
Interest in growing edibles and diverse plants has helped make citrus trees more popular and available, Rhoades said. Wouldbe growers can find a variety of lemon, lime and orange trees from which to choose.
“It’s easier for people to get a hold of citrus trees and they’re more willing to try to grow them,” she said.
“Try” might be the operative word, added Missy Henriksen of the National Association of Landscape Professionals. Growing citrus takes patience.
Dwarf fruit varieties, such as the calamondin orange, Tahitian orange, tangerine, kumquat, Meyer lemon and Kaffir lime are the best choices for growing indoors.
“Keep in mind, however, citrus trees are not for everyone,” Henriksen said. “They’re best suited for homeowners who are willing to devote the time and attention these plants need to thrive, or who can hire a landscape professional to regularly tend to their plants.”
Start by selecting a healthy plant, Rhoades said. Look for a tree with rich, glossy leaves. Next, make sure the container is large enough for the roots to grow, Henriksen said. Finally, place the tree in a spot where it will receive plenty of sun. You may want to supplement its exposure to light by using a grow lamp, she said.
Research the tree’s water needs and follow them closely, said Rhoades.
But check the soil each time before watering. “Check it on a schedule,” she said. “Don’t water it on a schedule.”
Sometimes it’s better to just mist the leaves with a spray bottle than to water the tree, said Barbara Pierson of White Flower Farm in Litchfield, Conn.
It’s also a good idea to move citrus trees outdoors during warm weather, said Greg Gatlin, interior account manager at Southern Botanical in Dallas. They can be outdoors as long as temperatures don’t dip below 10 C. When moving trees, make sure the temperature does not vary more than 15 degrees, as that can shock the plant.
Fertilizer also is important, Pierson said. She recommends using fertilizer designed for citrus. If that’s not available, use regular fertilizer, but make it with half the amount of fertilizer to the recommended amount of water. Fertilize once a month when the plants are indoors and twice a month when they are outdoors. If cared for properly, the plants will eventually produce small amounts of fruit. The Associated Press
