Land preparation:

Land is prepared before planting dragon fruit for 1-2 weeks. Use Benomyl (0.1%) to irrigate the soil before planting to prevent fungal diseases. Soil should be used to help drainage well. The size is 10-15cm high, 60-0.80cm in diameter.

Land used for planting dragon fruit is topsoil mixed with manure 15-20 kg (organic fertilizer: 10-15kg / head) + 500g super phosphate + Basudin (2g / tissue).

Growing season:

Dragon fruit can be grown year-round, it is best to plant in the spring and autumn.

Planting method:

Place the core to the ground, the flat surface of the dragon body hugged close to the pole and nylon pillars to the pole, each post placed four hom.

The new branches on the top of the pole will be pruned in principle: a branch, two twigs. Choose the healthy branches to leave. Frequently pruning moth ears, branches, insects, branches lying in the canopy, branches gave 2-3 years

Fertilizer application:

After planting for 2 weeks (for complete root crops) can use Urea + DAP or NPK 16-16-8 or 20-20-15 irrigation, dose of 20-30g / cylinder, 10 days / time

Trees 3-12 months using Urea + DAP or NPK 16-16-8 or 20-20-15 irrigate 30-50g / head, 15 days / time depending on soil type and increase with age.

Trees 1-3 years: Manure or organic manure can be used from 20-50kg / head / year, divided into 2 times. The first time when the tree is ready to bloom (February – March), the second time from September to October after the pods, the new branches and the new ones.
