– Then bring the seeds to incubate in a closed towel for about 2-3 days until the fangs crack.

– Mix the seed nursery soil at the ratio of 1 vermicompost: 1 coco peat and sow the incubated seeds.

– Use nursery trays/blisters or eggshells, banana leaves to incubate seeds.

After the seedlings have 2-3 true leaves, they are planted in the prepared container. It is necessary to dig holes in the crate with the size of 10cm deep and 5-7cm wide. Finally, place the seedling in the hole and gently install the soil.

In the first 2 days, it is necessary to shade the seedlings from the sun to avoid heat shock. New plants need to be watered 1-2 times a day in the early morning and cool afternoon.


– Handle gently to avoid breaking the roots of the seedling.

– If mixing soil according to the formula or using SFARM organic clean soil, there is no need to fertilize the plants.

In addition to sun-loving, melon is also a moisture-loving plant. Therefore, it is necessary to water twice a day in the early morning and in the cool afternoon to keep the soil moist enough for the plants. At the same time, always keep the planting soil well-ventilated to avoid the case of root rot that kills the plant.

When the melon begins to produce buds, flowers and results, reduce the number of watering times to 1 time / day. In particular, water in the area around the base of the melon tree.


Melon is a climbing plant, so it is necessary to build a strong, well-ventilated rig so that the tree can have lots of flowers and fruit. After about 1 month of planting, proceed to erect the truss for the tree to grow. The optimal height of the truss is about 1.5-2m.

Truss construction materials can be bamboo, wood, concrete pillars and specialized climbing nets for trees. Common types of truss are A-frame truss and vertical truss. Depending on the topography of the garden, make a suitable truss.

Pollination for melon

After about 2-3 months of planting, the plant begins to bud and flower. At that time, it is necessary to artificially pollinate the melon if there are few bees and butterflies in the garden.

It is advisable to pollinate early in the morning, before 9 am and avoid rainy days. Tear off the male petals, revealing the stamens. Then use the stamens to stir vigorously in the middle of the pistil of the female flower. Actions need to be quick, concise and decisive.


Melon requires a lot of phosphorus and potassium in the process of flower and fruit production. Therefore, it is necessary to choose a fertilizer with a balance of nutrients and minerals. Need to fertilize at the stage before flowering for melon. Should be fertilized with organic fertilizers (vermicompost, rotting manure, …) with healthy and balanced nutrition is the ideal choice for melons.

7/ Breeding melon

Melon is the simplest but best quality plant to propagate. Choose large, pest-free fruits and leave them on the tree until they are old. After the fruit is old, separate the seeds, remove the flat seeds and wash them. Leave in the sun for 2-3 days until the silk seed coat dries. Store seeds in a cool and dry place.

8/ Harvest melon

After 40-45 days of planting, proceed to collect the green melons. Melon has a long harvest time, so after the harvest, it is necessary to add organic fertilizer for the plants. Helps plants have enough nutrients for the next batch of fruit.

If the melon produces small fruit, it may be because the amount of pods reduces the nutrition of the tree. At that time, you should prune the fruit and add more nutrients to the tree.
