Halleys Comet dragon fruit

Halleys Comet dragon fruit dragon fruit

Halley’s Comet is a unique and ornamental dragon fruit hybrid that grows big fruits that can weigh up to 2 pounds! Halley’s Comet grows a little slower than some other varieties, which can be a good thing when you see how fast other varieties grow. Partially self-fertile, but you should still pollinate it with another variety to get the most fruit.


The Dragon Fruit is a plant that grows on the ground and has a fleshy stem. The plant grows quickly, needs little care, and does well in pots. Hylocereus undatus and Hylocereus guatemalensis are the parents of the Halley’s Comet Dragon Fruit.

The outside of the fruit is pink, with short green fins and purple flesh on the inside. Most fruits weigh between 1 and 2 pounds. The average brix of the flesh is 16, which means it is sweet.

The flowers are more than 13 inches across, and they bloom all summer long. Flowers are complicated and only bloom at night. This variety grows quickly and it can handle full sun with only a little sunburn.

My tests have shown that Halley’s Comet can set fruit on its own, but for the best results, you should use pollen from any Hylocereus polyrhizus.

Tastes a lot like Physical Graffiti, and from what we’ve seen, it can take up to 5 years to fully mature and start making fruit.

It is also used to add flavor to baked goods and drinks. Halley’s Comet could have up to four fruiting cycles per year when it is at its peak. Halley’s Comet doesn’t need to be cross-pollinated, and many people think it’s the best dragon fruit variety.

How to grow

Plant the dragon fruit cuttings an inch deep in soils that drain well (or in pots) that get full sun to partial shade. Any part of the plant can send out roots. Just stick the piece of plant in the ground and wait for it to grow.

Put a wooden plant stake that is three feet long into the ground about two to three inches away from the plant. As the plant grows, you can tie it to the stake with gardening tape, so it stays in place. Pitaya fruit has branches that can grow up to 20 feet long.

All dragonfruit also need a strong trellis to support the weight of the fruit and keep the branches from breaking.

When you first plant this cactus, you should water it often and not let the soil dry out between waterings. Dragonfruit usually recovers quickly from light frosts, but it needs to be covered or moved inside when the temperature stays close to or below freezing (32°F, 0°C) for a long time.

Plant facts

  • It has pink flesh and a great taste. It is related to Physical Graffiti, but it is not as “strong” or productive;
  • Paul Thomson wrote it in the early 1980s in San Diego County, California;
  • The fruit is round, big. The flesh is hot pink, and the seeds are small. The rind is bright red, thin, and has an average number of bracts. The quality is very good at 16.7 Brix, and it scored high in sensory tests. It takes 38 days from bloom to harvest in Southern California, and it can be picked from July to December;
  • The plant has medium-thick stems with 3 well-defined ridges; the mature stems are mostly straight and dark green; the areoles have 1-3 spines that are 2-4 mm long; the segment between the areoles is convex and 53.6 mm long; the flowers have medium-thick petals that are white, a yellowish-green calyx, yellow anthers, and yellow stigma lobes;
  • It can handle both cold and heat well, grows well in full sun, and has a good chance of making money.


Halley’s Comet is a cross between a red flesh dragon fruit and a white flesh dragon fruit. The flesh of this hybrid is a beautiful magenta color, and the skin is pink to red. The skin of the fruit is pink, with green tips on the fins. The meat is hard, light, juicy, sweet, and sour. It is very refreshing and tastes like a sweet plum or strawberry.

This pitahaya fruit is between medium and large in size: it weighs 1 to 2 pounds and is sweet. Like other dragon fruits, Halley’s Comet has a unique and delicious taste. You can add it to your favorite drink or smoothie, or you can eat it fresh.

This variety has been shown to be a good producer and grow fairly quickly. This variety can bloom all summer long and can pollinate itself, but it can produce even better results if it crosses with another variety. Both commercial growers and people who grow plants at home should pay attention to this variety.


Is Halley's Comet dragon fruit self pollinating?
Partially self-fertile, but you should still pollinate it with another variety to get the most fruit.
What is the best fertilizer for dragon fruit?
An inorganic fertilizer of type 6-6-6 or 8-3-9 is good for your Dragon fruit. A 20-20-20 mix can be useful sometimes as well. Use plant fertilizers that dissolve in water, like 20-20-20, to feed the plants once in early spring and again after the flowers have disappeared.
What kind of soil is best for dragon fruit?
For the soil, choose potting soil that drains well and has a lot of organic matter. Dragon fruits don't like "wet feet," or roots that stay wet. Don't use cactus soil, because dragon fruits are tropical plants that need more water than other cacti and need something that holds water a little better.
How deep do dragon fruit roots go?
During vegetative growth, the roots of dragon fruit plants are only 8 to 12 inches deep. But when they start to flower and bear fruit, dragon fruit roots can grow up to 24 inches into the ground.
How fast do dragon fruit cuttings grow?
Cuttings will grow quickly and might bear fruit 6–9 months. If you'd rather try growing plants from seeds, cut a dragon fruit in half and scoop out the seeds. In a bucket of water, separate the pulp from the seeds.
