Choosing the Right Variety
The first step in growing Japanese watermelons is selecting the appropriate variety. There are several popular options to choose from, each with its unique characteristics:
- Sugar Baby: A classic variety known for its small size, round shape, and intense sweetness.
- Moon and Stars: A visually striking watermelon with a dark green rind adorned with yellow spots, offering a balanced flavor and crisp texture.

Preparing the Soil and Planting
Japanese watermelons thrive in well-drained, fertile soil with a pH between 6.0 and 6.5. Prepare your planting area by tilling the soil deeply and amending it with organic matter such as compost or manure.
Plant the watermelon seeds directly in the soil in late spring or early summer when the soil temperature has reached at least 65°F (18°C). Space the seeds 2-3 feet apart in rows that are 6-8 feet apart. Plant the seeds 1-2 inches deep and water them well after planting.
Watering and Fertilizing
Watermelon plants require regular watering, especially during hot and dry weather. Water deeply at the base of the plant, avoiding getting the leaves wet. Fertilize the watermelon plants every few weeks with a balanced fertilizer.
Mulching and Weeding
Mulching around the watermelon plants helps retain moisture, suppress weeds, and regulate soil temperature. Use organic materials such as straw, hay, or shredded leaves for mulching.
Regular weeding is essential to prevent competition for nutrients and water. Hand-pulling or hoeing weeds is recommended to avoid damaging the watermelon plants.
Pollination
Japanese watermelons require pollination to produce fruit. Male and female flowers are present on the same plant, but pollination requires insects such as bees or wind to transfer pollen from the male to the female flowers.
To encourage pollination, provide a source of nectar for pollinators by planting companion plants like clover or wildflowers near the watermelon patch.
Trellising
Trellising watermelon vines helps keep the fruit off the ground, reducing the risk of disease and improving fruit quality. Trellises also provide support for the heavy vines and allow for better air circulation.
Use stakes or trellises to support the vines as they grow. Gently train the vines onto the support structures without damaging the stems.
Monitoring for Pests and Diseases
Japanese watermelons are susceptible to various pests and diseases, including aphids, cucumber beetles, and powdery mildew. Regularly inspect your plants for signs of infestation or disease.
Use organic pest control methods such as neem oil or insecticidal soap to manage pests. For disease control, practice crop rotation and avoid overwatering.
Harvesting
Japanese watermelons are ready to harvest when the rind has turned a dull green color and the underside of the fruit has a yellow spot where it rested on the ground. Gently tap the watermelon with your knuckles; a ripe watermelon will produce a hollow sound.
Cut the watermelon from the vine with a sharp knife, leaving a short stem attached. Handle the fruit carefully to avoid bruising.
