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.

Choosing a Pot

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.

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.

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.
