Everything You Need To Know Before Growing Korean Melons

Before we learn how to grow Korean melons, you need to know that certain environment prerequisites must be in check to ensure that you get the best produce. Let us address them one by one.



It would help if you shopped for a top-notch variety of seeds only from an authentic dealer for growing Korean melons. The melons need fertile, slightly acidic, and well-drained soil to ensure good air circulation for the melons to grow. Ideally, the soil’s pH levels can be between 6.0 and 6.5. When the ground is fairly warm during the spring season, you have to loosen the soil to approximately 12-inches deep.


After that, you need to prepare a 3-inch compost layer. In it, add a little organic fertilizer. Next, create wide but small, elevated hills in the soil as melons grow on vines. In there, the plants will trail and branch. On every hill, you will have to plant around three to five seeds. Keep space of approximately 2-inches in-between the seeds, and they should all be about an inch deep.


Further, be very careful with the watering of your plants. Before watering again, you need to ensure that the soil is moderately dry. The Korean melon plant is unable to grow in cold, frost, and wet soil.


Keep a close check on your growing melons, and eliminate all the weaker ones. Allow the two visibly taller plants to grow on the hill. Ensure that there is a 2-feet space between two adjacent plants. When you plant the seedlings, the holes must be as wide and deep as the root balls.


If you live in colder conditions, you can grow your Korean melon plant indoors and then transplant them outside when the weather is relatively warmer. If you want to grow your plants outdoors, you should lay a plastic mulch over the ground to ensure that the ground below is warm.



Korean melon plant grows well at 60 and 84°F temperature. During the daytime, the ideal temperature range is 75 to 84°F, and during the night hours, it is 60 to 75°F.



Korean melon plant needs sun all-around the day. For proper growth, they need approximately 50-55 warm days.



For settling the soil, you need to give your plant approximately 2-inches of water. After settling, the Korean melon plant will require around 1-2 inches of water per week.



You need to evenly spread approximately 2-inches of organic mulch in a 2-foot circle around your Korean melon plant. It is necessary to enable the soil to retain moisture.



You have to add a tablespoon of 33-0-0 fertilizer to the soil a week after your Korean melon plant blooms. Make sure it is around 3-inches far from the plant’s base.


Pest control

Some of the pests that tend to attack the plant include cucumber beetles, squash bugs, and aphids. The plant is also vulnerable to bacterial wilt. Powdery mildew hampers the quality and taste of your fruit. Thus, we would recommend you to go for the pest-resistant varieties.



The ripe oval-shaped melon has bright-yellow skin and weighs approximately 300 – 500 grams when it is ready for harvesting.


Step-by-Step Process For Growing Melons

Step 1

Take two seeds in every 9 cm seed compost pot. Water it nicely, and then keep the pot in a propagator at 18°C temperature. Make sure your propagator is kept in a well-lit position.


Step 2

Following germination, you need to remove the seed, which appears weaker. Make sure your compost is moist and not very wet. After some leaves emerge, you have to reduce the propagator temperature to around 15°C.


Step 3

Plant the melons in late spring to early summer. For a thorough development, you have to pinch the main growing point to two or three buds to encourage the development of side shoots.

Step 4

When the plants establish, go ahead and tie the long main stem for adequate support. Ensure that the compost remains moist throughout. So, you will have to keep a check on your plant every day. To facilitate requisite growth, you need to add a liquid feed every once a week. To ensure that the plants do not become very crowded, pinch the side shoots after three or four leaves every week.

Step 5

Melons yield both female and male flowers. In the female counterpart, there is a fruit developing behind the bloom. On the other hand, in the male flower, there is a thin stalk. Usually, the insects will pollinate the flowers. However, in your backyard, you will have to hand-pollinate.


Step 6

For planting, you need to pick a sunny and warm day when the flowers are thoroughly open. Opt for a healthy male flower, and get rid of its petals to see the inside of the bloom wherein they yield pollen. Transport the male flower into the female one.

Step 7

Next, you will have to thin out all the developing fruits to ensure that not over four melons grow in a pot. When the fruits grow, you need to water them thoroughly and feed them with a high potash liquid feed. Anytime you can sniff a sweet aroma, you know that your fruits have ripened. So, when the stalk’s opposite end softens, skin changes the color, and tiny cracks appear around the stalk on the fruit, you know it is time to pick.


With that, we hope you have a fair idea of how to grow Korean melons.


Caution And Growing Tips

  • If your Korean melon plant is blooming but not setting fruit, do not worry. Usually, the earliest flowers are male, which are pollen-bearing, and do not develop into fruits. Only your female flowers will yield melons. If pollination does not happen, both the fruit and the flower will fall from the stem.
  • Make sure you grow the plant in the ideal weather and temperature conditions. If you fail to do so, the fruit will lack flavor.
  • Insufficiency of adequate elements, for instance, fertilizer, well-drained and fertile soil, and water, tends to weaken the plant. If you are growing a week plant, it is more prone to a pest attack.
  • As the Cucurbitaceae crossbreeds easily, you should ensure that there is adequate space between two different cultivars or kinds of melons.
  • Even though the seeds and the melon’s skin are edible, you should remove some seeds and put them on paper. These will help you when you have to plant a new Korean melon plant.
