Dragon Fruit Propagation

Growing Dragon Fruit from Seeds

  • With a knife, divide dragon fruit in half and scoop out the black seeds from the pulp. Wash the pulp off the seeds. Put these seeds on a moist paper towel and leave them overnight.
  • Fill the germinating tray or small pot with well draining but poor starting mix. You can make it yourself by mixing one part peat and one part perlite. Sprinkle the seed on the soil surface and cover that with a thin layer of growing medium that barely covers the seeds.
  • Thoroughly moisten the soil using a sprayer and cover the pot with plastic wrap. Keep the soil moist until seeds germinate, which will take around 15 to 30 days.
  • After the seeds germinate, uncover the plastic and transplant them to bigger pots when necessary.

Growing Dragon Fruit from Cuttings

To learn how to propagate dragon fruit from cuttings, read this guide.

Dragon fruit propagation from cuttings is easy, but if you’re not growing this plant on a large scale, it’s better to look out for grown-up plants in nurseries or online.


Growing Dragon Fruit in Pots

If you’re living in a cool climate or if you’re an urban gardener and don’t have much space, grow dragon fruit in a pot, it’s fairly easy to grow and adapts itself well in containers. In the pot you can move and overwinter it to save from frost as pitaya plant can survive a very short duration of freezing temperature (below 28 F is detrimental) and frost.

Choosing a Pot

Select a pot according to the size of the root ball of your plant, one or two sizes bigger. Start the plant in a 5-gallon, 10-12 inches deep container and keep repotting yearly or when the plant seems root bound. A large 25-30 gallon size pot that is around 20-24 is enough to accommodate a mature dragon fruit tree. Be extra careful while repotting if you’re a novice.


Requirements for Growing Dragon Fruit

Location

Dragon fruit is a cactus, which means it loves heat and sun. It’s better to plant it in a spot that is dry and sunny. If you live in a hot climate, it’s best to choose a location that remains partially shaded.

Support

Dragon fruit plant is actually a climbing cactus and needs support to climb on, usually, as the plant becomes mature, it forms aerial roots from the branches and finds something to climb. So, it’s best if you’re growing dragonfruit, find something to support your plant. Attach a sturdy trellis or make an arbor.

Soil

For growing dragonfruit, opt for well-draining soil that is sandy and loamy. A mixture of sand in garden soil would be appropriate. It is forgiving to poor soil.

Water

Since the dragon fruit is a cactus, water it moderately with care like you do with other succulents. Water only when the soil dries out.

Temperature

Dragon fruit plant can’t live in cool temperatures. Exposure to a temperature below 32 F (0 C) is fatal. Similarly, the temperature above 100 F (38 C) causes difficulty. In a cool climate, keep the plant in temperature above 50 F (10 C). In a hot climate, save the plant from afternoon sun in summers and place it in a partially shaded spot.


Dragon Fruit Care

Fertilizer for Dragon Fruit

Fertilize dragon fruit with a balanced fertilizer every month when the plant is actively growing in its growing season. Stop fertilizing in winter if you’re growing it in a cool climate. Side dressing with aged manure or compost can also be done occasionally.

Dragon Fruit Pruning

Pruning is required to train this plant on the trellis, improve air circulation and prevent fungal infection and maintain its height, otherwise, it can grow up to 20 feet tall in the optimum growing conditions. Prune it annually by removing all the overgrowing, decaying, overcrowding, and dead stems saving only the healthier and productive ones. Check out this pruning guide to learn more!

Note: Must care to disinfect your pruning tool before the job.

Pests and Diseases

There are particularly no pests that nag the plant seriously. Although keep an eye on aphids, they feed on young shoots and flower buds. Fungal diseases and root and fruit rot are possible if the plant is overwatered or exposed to too much rain.


Dragon Fruit Pollination

Many dragon fruit varieties are self-pollinating, but there are some that require cross-pollination. If your dragon fruit is unable to self-pollinate, you’ll need to grow two or more dragon fruit plants closely for cross-pollination. As dragon fruit flowers are nocturnal, its pollination depends on moths and bats. For assurance, you can also do this at night.

Harvesting

  • In usual climates, dragon fruit bears fruit multiple times from summer to late fall and probably winter. It depends on the climate.
  • If you’re growing it in a temperate region, it’ll fruit between summer to early and mid-fall.
  • Your dragon fruit tree will start to produce flowers and fruits once it is established. This will happen in the first or second year after planting.
  • Harvest dragon fruit when its skin color changes from bright green to red or pink. Its fruit is oval to ovate in shape and 10 to 15 cm long and forms 30 to 50 days after flowering.
  • The pericarp of dragon fruit is rough and scaly and is usually pink in color. However, there are also red, or yellow dragon fruits depending on the variety. The flesh is located in the interior is white and contains black seeds.

  1. I Wana start dragon fruit in Nepal. If it’s possible to sent seeds or plant plz reply my
    Mail we will discuss about it.thank you so much.

    • Thank you for your interest in our site although we don’t sell seeds or plants.

      If you want to grow it, you can buy seeds or plants online. There is a website from your country which is selling dragon fruit seeds you can check it out here. Alternatively, you can buy it from amazon or eBay.

  2. Question for you? Sometimes, my dragon fruit plants has flowers and before it blooms, it dies out with no fruit? Am I doing something wrong? Also, how do you increase the number of flowers/blooms?

      • Same here iv been just patient for it to bear fruit the plant has grown tall and spreading its cactus on the pillar and it’s almost three years now but no fruit as yet .

      • It sounds like you most likely have a plant that itsnt self pollinating. This just means that you will need pollen from a seperate plant to cross pollinate. Ive done this by hand myself and it worked. I simply searched on the internet how to pollinate a drangonfruit flower. Hope this helps. Best of luck.

    • Dragon fruit plant is a type of cactus and requires very less watering. It is a hard plant and usually no pests affect it. However, excess watering develops fungus and rot and damages the plant. Water the plant only when soil is completely dry. Enrich the soil with compost, potash, sSSP and very little urea.

    • Your plant probably is not being pollinated. You can try hand pollinating it. While the flower is open take a cotton swab and from a different plant, gently wipe some pollen off of it, then return to the plant you would like to pollinate, and take that pollen and put it inside the flower. Hope this helps!

  3. Sir, I have completed my m.sc. horticulture, I am interested in growing of dragon fruits. Please provide information and economics of cultivation

  4. I have grown black java plum ( jamun) about couple years grow from seeds. please can advice how long does it take have fruit. one of the plant is shredding leaves. i have grown plant in UK

  5. Dragon fruit plants are actually a tropical plant and you may need to water it more than a normal cactus. Also, unless you have the particular bats or rodents in your area for pollination, you will need to hand pollinate the flowers when they bloom at night. Some varieties bloom more than once before the flower dies. I live in the sun-tropics and my dragon fruit likes full sun, not partial. Thanks.

  6. I live in south fl. Neighbor just gave me a dragon fruit plant. In a small pot. Should i replant to nigger pot or can i divide this plant into 2 or more?

    • You may have a plant that is not self fertile. If you can get another plant, use a small brush to move pollen from one plant to another. Or if you know someone with another plant, you both can collect pollen and exchange it. For more flowers, use a balanced fertilizer 15-15-15 or 10-10-10.

    • hi, Samantha~
      I brought home a cutting from my son in California, last year. (He grows EVERYTHING!!!) I live in WA, so it’s a potted indoor plant, just as you will need. I have it near a southern window, so it gets plenty of light, and it seems to be happy. Growing happily, with lots of support, it looks like an elongated bowl of green spaghetti :-) About 18″ tall, but if I stretched out all the branches & tendrils…? Matt’s is about 6 1/2′ tall, in a huge pot on his outdoor patio. Mine is still too young to bloom yet, but I’m very hopeful for the future. I’ll probably bring back another piece when I go down for Christmas, next week, just in case. Maybe a piece of his Buddha Hand, too! :-)
      Best wishes, Marina
