  • Sprinkle the seeds onto the surface of the soil and cover with a thin layer of the growing medium, barely covering the seeds.
  • Moisten the soil with a spray bottle and cover with plastic wrap to keep moisture.
  • The seed should germinate within 15-30 days. During this time, keep the soil moist.
  • After they've germinated, remove the plastic wrap, and transplant to a bigger pot.

How to Care for Dragon Fruit

How to Fertilize Dragon Fruit Plants:

During its growing season, fertilize once a month with a balanced fertilizer. If growing in a cooler climate, stop fertilizing in the winter. Side dress with aged manure or compost to keep moisture in.

You should prune dragon fruit plants on a regular basis to control size and improve air circulation. This will also help prevent fungal infections and diseases. If left to its own devices, the tree can grow up to 20 feet in height. Prune the tree annually by removing any dead stems as well as overgrowing stems.

Dragon Fruit Diseases and Pests:

Normally, there are no real pests or diseases that can seriously affect the dragon fruit, but do watch out for aphids. Aphids will usually be found feeding on young buds and shoots. Also, be careful when watering the dragon fruit plant, as over-watering can cause root rot as well as fruit rot.

How to Pollinate Dragon Fruit:

Most dragon fruit varieties are self pollinating, but there are a few varieties which do require cross-pollination, also known as hand pollination. If that is the case, you'll need to grow two or more plants close to one another so they can cross-pollinate. Cross-pollination will usually occur at night since pollination depends on moths and bats. Make sure the soil is well draining, and always moist.

Once dry, water deeply and be sure that your pot has good drainage holes. Never let your dragon fruit plant sit in water as this can cause root rot. For a young plant, you may have to water every day or every other day. As the plant matures, this schedule may change. Watering dragon fruit depends on the climate, humidity, and age of the plant.

  • You can harvest dragon fruit once its skin color changes from bright green to red or pink.

  • Fruits should be ready to harvest 30-50 days after flowering.
  • In a regular growing climate, dragon fruit will grow from summer to late autumn, and even into winter.
  • In temperate regions, you'll be able to harvest dragon fruit between summer and early to mid autumn.
  • The dragon fruit plant will start flowering in its first or second year after planting.

Growing the dragon fruit plant in pots is not that much different than growing them in the ground. In fact, it can be much easier, since the pots can be moved to accommodate the plant. In hotter climates for example, the plant may need more shade and therefore will need to be moved.

There are two ways you can grow dragon fruit in pots. The first way involves growing the plant from cuttings, and the second way is to plant seeds. Whichever method you choose, keep in mind that growing dragon fruit from seed could take up to 6 years to product fruits, whereas growing from cuttings will only take a year or two. Obviously, growing from cuttings is the most popular method, but it can also be quite difficult to achieve, especially for beginner gardeners.

Method #1: Growing From Cuttings

  • Cut a 6-15 inch (12-38cm) stem from a plant (the parent plant) that is at least one year old. Make the cut at an angle for best results. Let the cut stem heal for about a week in a dry place.
  • Choose a container that's big enough to support the plant and ensure it has good drainage holes. The pot should be at least 20-24 inches deep and hold 25-30 gallons.
  • Because dragon fruit is part of the cactus family, it prefers cactus soil, or well draining soil. The should should also be slightly acidic, with a pH of 6-7. Alternatively, you can make your own cactus soil at home by mixing in sand/perlite, organic manure, and compost, using the following ratio respectively: 2:3:1:1.
  • Fill your pot with the correct soil, and water the soil well. Wait until the soil has absorbed all the water and is draining properly before planting.
  • Dig a hole in the middle of the soil that's at least 2-4 inches deep and place the cutting inside of it, packing the soil firmly around the stem.
  • Follow the same care directions as above.

Method #2: Growing From Seeds

  • Be sure to acquire good quality, preferably organic seeds from a reputable seller.
  • Follow the same directions as above (for growing dragon fruit from seeds) and plant in a big pot with good drainage holes.
  • Again, make sure the soil is suitable for this type of plant and that is is well watered.

Please note that growing dragon fruit can take several years to bear fruit, but in the meantime, you'll have a stunning flowering cactus!
