Which Month Is Best For Planting Dragon Fruit?

You can generally cultivate dragon fruit year-round. Being a resilient and cactus-type plant, you can nearly always plant cuttings or seedlings.

How Will The Pot/Drams Be Suitable For a Rooftop Garden?

You can use plastic drums to grow dragon fruit in your rooftop garden. But it is best if you choose a 20-inch drum. Because in this size drum, the seedlings can spread the prey well, and the yield will be much better.

Tub

How To Prepare The Soil of The Tub To Grow Dragon Fruit Farming on The Rooftop Gardens?

Dragon fruit is best grown in soil rich in organic matter. The success of growing plants in tubs/pots depends largely on the preparation of the soil mixer.

You must remove unwanted matter from the soil by pulverizing the soil. Take the required amount of soil, mix 0.5 grams of dolomite Powder ( The powder rich in Calcium and magnesium) for every kg of soil, and wrap it in polythene for 8-10 days.

Urea at the rate of 1 gm, Triple Super Phosphate(TSP), and Muriate Of Potash (MOP) at the rate of 0.5 gm should be added to the treated soil by mixing a quantity of bio-fertilizer / Trico-compost and coco peat per kg of mixture. In pots/tubs/ Drams, the ratio of soil: compost: cocopeat mixture will be 2:1:1.

Soil Mix

How To Fill The Soil in The Tub/Dram?

For adequate drainage of excess water from the tub, it is advisable to create three to four holes at the bottom, each measuring approximately 2-3 centimeters. If creating holes isn’t feasible, position 3/4 brick pieces over the holes to prevent soil blockage.

While filling the tub with soil, you should keep 0.5 to 1 inch on top of the tub and 1.0 to 1.5 inch in case of half drum free for proper fertilization and watering.

Fill the tub/pot/drum to the specified height with manured soil. It would help if you planted Dragon cuttings or seedlings after leaving the filled pot/drum for 12-15 days.

Soil mixture fills up the tub.

How To Do Irrigation And Water Management in Dragon Fruit Farming in Rooftop Gardens?

Irrigation management is the most important aspect of dragon fruit in roof gardens. However, you can give little water to the cultivation of cactus plants.

Take special care in watering after planting dragon cuttings/seedlings so that water does not accumulate at the base.

The success of roof garden establishment depends on regular moderate irrigation. Just as under-watering is harmful, over-watering is also harmful to plants.

Due to excess watering, various diseases occur in tub/potted plants. Even trees/plants die.

Only watering the plant when the roots are dry is essential to ensure healthy growth. If the roots are already wet, refrain from watering. Reduce the water given during flowering but continue to provide a small amount regularly at the base. Otherwise, the lack of water may disrupt the flowering of the dragon tree in the roof garden.

How To Care For Dragon Fruit on The Rooftop Gardens?

Proper care of the dragon fruit tree is essential to achieve a good yield. Dragon trees face various diseases, but consistent environmental care significantly reduces the risk of these diseases.

After planting, you should keep the drum in a sunny place. Because the stems of the dragon tree are like vines, they should tie them to the poles as soon as the tree grows lightly so that the tree does not fall easily.

You should cut the side shoots of the dragon tree regularly; it improves the tree’s growth.

Dragon Fruit Collection:

You can harvest good quality dragon fruit nine to 14 months after planting. Usually, flowering starts in April; the fruit is ready to eat only 35-40 days after flowering.
