How to Grow Dragon Fruit in a South Window
Dragon fruit (Hylocereus undatus), also known as pitaya and nightblooming cactus, is a quick-growing, cactus hardy in U.S. Department of Agriculture plant hardiness zones 9 to 10. Dragon fruit is best known for its unique fruit, a fleshy, oblong berry with a red or yellow peel and scales. Though dragon fruit stems can grow up to 20 feet long, dragon fruit responds well to pruning to keep it small and can be grown in a container indoors near a window with plenty of sunlight.
Place the pot approximately 2 feet away from a south-facing window that receives full sunlight during the day. Windows that are not shadowed by outside obstructions such as bushes, awnings or trees are ideal, since too much shade can result in poor fruit production. Do not place dragon fruit too close to the glass because it is susceptible to sunburn, especially within the first 3 to 4 months as it adapts to this new indoor location. The University of Florida Extension recommends 30 percent shading during this time and full sun thereafter.
Wait until the dragon fruit has bloomed in the summer and then water it once deeply until the soil is saturated and no more water can be absorbed. Wait until the soil dries out entirely before the next watering. A dry period is required to induce blooming, so do not water before flowers appear. Though dragon fruit is a member of the cactus family, is has a fairly high water requirement. Dragon fruit should be planted in a pot with well draining soil and drainage holes.
Keep indoor temperatures above 50 degrees Fahrenheit and ideally between 65 and 70 degrees Fahrenheit. Do not allow temperatures to exceed 100 F. Too hot or too cold temperatures can kill dragon fruit.
Fertilize dragon fruit starting one month after planting. In the first year, fertilize once every 2 months using a 6-6-6, 8-3-9 or 8-4-2 fertilizer. Apply at a rate of 0.25 pound per plant. In the second and third year, slowly increase the amount of fertilizer to 0.40 pound per plant, applied every 2 months. In the fourth year and after, apply between 0.50 and 0.75 pound of fertilizer per plant 3 to 4 times a year.
Wipe hand pruners with 70 to 100 percent isopropyl alcohol using a clean rag to disinfect them. Always sanitize pruning tools before use to avoid spreading or introducing disease. Cut 1 to 2 inches from the tips of the stems with a pair of hand pruners after the dragon fruit has finished flowering in the early fall. Selectively remove any dead, damaged or crowded stems by snipping each stem 1/2 inch above the base. Pruning will control growth and encourage flowering next season.How to Grow Dragon Fruit in a South Window.

How to Grow Dragon Fruit Indoors
Dragon Fruit [pitaya or pitahaya] is produced by several different cactus species. Pitaya is the original name of what we now call Dragon Fruit.
In the early 90s, it was marketed in North America as dragon fruit and the name has stuck. It is sometimes referred to as strawberry pear or thang.
Dragon Fruit originated in Mexica and Central America but is now cultivated commercially in the Southwest USA, Florida, Southeast Asia, the Caribbean, and Australia.
The skin is leathery and bares protrusive scaly spikes. The spikes are fairly soft and don’t prick you as many other cacti do. The small seeds are similar to that of kiwi and lend a crunchy texture to the fruit. The pulp of the mature fruit is mildly but pleasantly sweet.
The flowers are also edible and used to make a tea.
They thrive in USDA zones 10–11. It is highly adaptive to its environment and can be grown as far North as zones 8 & 9 but not as abundantly. Dragon Fruit will endure temperatures over 100 o F, But long durations at these temperatures has been known to damage the fruit.
Dragon Fruit will also survive short bursts of frosty weather. They will not survive extended periods of freezing temperatures. Optimal temperatures for growing dragon fruit is between 65 and 85 degrees o F.
Growing Dragon Fruit In Containers
They also do well as potted plants grown indoors in cooler regions, a greenhouse, Florida room or sun-drenched porch would be just dandy, but a sunny window will suffice.
At least 6-8 hours of sun is needed. The container will need adequate drainage, several drainage holes. The container should also be large enough to accommodate a large plant. There are several popular varieties of Dragon Fruit that vary a tad in size but generally, a 3 – 5-gallon container is suitable to start. You can transplant it at a later date if need be when starting to form a smaller pot, but you may lose some in the process.
NEVER, ever allow the roots to become soggy, they are cacti, overwatering will surely be the end of them.
Seeds can be started in a potting soil mix made for cactus plants that is sandy and well draining or very dry compost with sand.
It is a vining cactus, so a support structure / trellis is advisable. In a container cactus it will flow over the edges. Outdoors it will sprawl along the ground.
Staring Dragon Fruit from Seeds
Dragon Fruit Seeds can be purchased or self-collected. If using seeds you gleaned yourself they should be thoroughly cleansed of fruit pulp and stored till dry. It is advisable you use only the best Dragon Fruit specimens for seed saving, free of blemishes and over-ripe.
Seeds under the right conditions, will germinate within a week give or take a few days either way.
Growing Dragon Fruit from Cuttings
Even though they are not that difficult to start from seed, cuttings are a good way to go. Grown from seeds they take much longer to bear fruit and have a lower survival rate. Cuttings will sprout roots with or without soil and are generally ready to plant within a week.
Cuttings should be 1/2 ft to 1.5 feet and taken from a healthy vine. Cut through the vine at a slight angle in order to expose a larger surface area.
I like to spread a thin layer of honey over the exposed cut. Honey works well as a rooting hormone the benefits of Honey as a rooting agent are three-fold – enzymes to stimulate new root growth, anti-bacterial and anti-fungal properties to curtail infection, and nutrients via its natural sugar content. A win, win and win again menage trios of properties/qualities. See: Honey as a Rooting Agent .. Fungicidal rooting hormone powder will also work
DO NOT put the cutting in water as is done with some plants – remember it’s a cacti. Place the cutting in a dry area out of sdirect sunlight, but not completely in the dark either. Wihin about a week you should see should roots sprouting from the cut area.
Fill your container with a suitable potting mix and place the cutting root end down roughly 2 inches below the soil surface. You don’t need to have any part above the soil, as it grows it will seek out the sunlight by itself.
The potted cutting should not be in direct sunlight – partial diffused light is best. Water the soil very lightly twice monthly and only after it has dried out completely.
Don’t transplant till the plant is 6 to 8 weeks old and producing helathy growth.
If planning on transferring them to the great outdoors you should wait 5 – 6 months for them to be strong enough and have developed an adequate root system.
How to Pollinate Dragon Fruit
A strange thing about these cacti is that they flower at night and do so up to 6 times a year. Most varieties need pollination, they are not self-fertile, bees and most butterflies are not out at night to do the trick.
In nature they rely on bats and moths for pollination, Growing them indoors? … got bats and moths in your house – No – didn’t think so. If you keep them indoors and want to get fruit you’ll need to hand pollinate See: Indoor Pollination. There are several varieties of Dragon Fruit produced via cross-breeding that are hailed as self-fertile but cross-pollinating with a second plant increases fruit yield and quality.
Dragon Fruit Pests and diseases
Excessive moisture from heavy rain or overwatering can cause the fruit to rot and flowers to drop. Mature fruit will sometimes burst and split. Stem rot, brown spots on the fruit, and some fungal issues do occur – but rarely.
