What Are The Different Watermelon Growing Stages

Watermelon, a quintessential summer fruit, delights us with its refreshing taste and juicy texture. Whether enjoyed on its own, in fruit salads, or as a key ingredient in various recipes, watermelons are a staple during the hot months. Have you ever wondered about the journey of watermelon from a tiny seed to a delicious, fully-grown fruit?

In this article, we will explore the stages of watermelon growth, providing insights into each phase and offering tips to ensure a successful harvest.

Watermelons are synonymous with summer, evoking images of picnics, barbecues, and sweet refreshments on hot days. Their vibrant red flesh, coupled with their juicy and cooling qualities, make them a favorite fruit for many. But have you ever wondered how these delicious fruits come to be? Let’s delve into the fascinating world of watermelon growing stages and uncover the secrets behind their journey from tiny seeds to succulent fruits.

The Seed Stage

Watermelon growth begins with selecting quality seeds that will yield healthy and flavorful fruits. It’s crucial to choose reputable seed suppliers to ensure you’re getting viable seeds. Once you have your seeds, prepare the soil by removing any debris and weeds. Watermelon plants thrive in well-draining soil, so ensure the area has good drainage.

Plant the seeds in a sunny spot, about an inch deep, and cover them with soil. Water the area thoroughly, keeping the soil moist but not waterlogged. Within a week or two, you should see the first signs of germination—a true cause for excitement!

The Germination Stage

During the germination stage, watermelon seeds awaken from their dormant state and sprout into seedlings. This stage requires consistent warmth and moisture. Optimal soil temperatures for germination range between 75°F and 85°F (24°C and 29°C).

To protect your tender seedlings, it’s essential to keep them safe from pests. Consider using physical barriers, such as row covers or netting, to prevent insects from damaging the young plants. Water the seedlings gently, taking care not to dislodge them from the soil.

The Seedling Stage

Once the seedlings have emerged and grown a few sets of true leaves, it’s time to transplant them into the garden or larger containers. Choose a sunny location with well-drained soil for transplanting. Space the seedlings at least two feet apart to allow ample room for their vines to spread.

Watermelon plants require full sun to thrive, so ensure they receive six to eight hours of sunlight daily. Adequate watering is crucial at this stage, as young plants are more susceptible to drying out. Mulching around the seedlings can help retain moisture and regulate soil temperature.

The Vegetative Stage

During the vegetative stage, watermelon plants focus on developing strong vines and leaves. To promote healthy growth, consider pruning and training the vines. Regularly remove any side shoots or suckers that divert energy from the main vine.

Applying a balanced fertilizer rich in nitrogen can provide the necessary nutrients for robust vine development. Be mindful of signs of nutrient deficiencies, such as yellowing leaves, and adjust your fertilizer application accordingly.

The Flowering Stage

As watermelon plants mature, they transition into the flowering stage, an exciting period that marks the onset of fruit production. Pollination is crucial for fruit set, so attracting pollinators to your garden, such as bees and butterflies, is essential. Consider planting companion flowers that attract these beneficial insects.

During flowering, you may encounter challenges like blossom drop, where flowers fall off prematurely without setting fruit. Factors such as temperature extremes, inadequate pollination, or stress can contribute to blossom drop. Maintaining consistent environmental conditions and ensuring proper pollination can help mitigate this issue.

The Fruit Development Stage

The fruit development stage is perhaps the most anticipated phase of watermelon growth. As the fruit begins to develop, it’s important to provide support for the vines by using trellises or slings to prevent them from breaking under the weight of the growing melons.

Watermelon plants have high water and nutrient demands during this critical stage. Regular irrigation, preferably through drip irrigation or soaker hoses, helps maintain consistent soil moisture. Monitoring for pests and diseases is also crucial to protect the developing fruit.

The Ripening Stage

Determining the ideal time to harvest watermelons can be a challenge. Several indicators can guide you, such as changes in skin color, a dull sound when thumping the fruit, and the drying out of the curly tendril closest to the fruit stem. Harvesting watermelons at their peak ripeness ensures the best flavor and texture.

After harvesting, store watermelons in a cool and dry place. They can last for several weeks if stored properly. To enjoy their juicy goodness, slice the watermelon and savor it as a refreshing snack, blend it into smoothies, or use it in creative culinary creations.

Here are the stages of watermelon growth with pictures:

Stage 1: Seedling

Watermelon seedlings are small and delicate, with two cotyledons (seed leaves) and a thin stem. They need to be kept warm and moist until they are established.

Stage 2: Vine

Once the watermelon seedlings have established themselves, they will begin to grow vines. The vines can grow up to 20 feet long, so it is important to provide them with support.

Stage 3: Flower

Watermelon plants produce both male and female flowers. The male flowers are small and yellow, while the female flowers are larger and have a small watermelon fruit at the base.

Stage 4: Fruit

Once the female flowers are pollinated, they will begin to develop into watermelon fruits. The fruits will grow rapidly and can reach up to 10 pounds in weight.

Stage 5: Ripe Watermelon

Watermelons are ripe when they have a deep green rind and a hollow sound when tapped. The flesh of a ripe watermelon should be red and sweet.

To help you identify when a watermelon is ripe, here are some tips:

  • The rind should be deep green and have a dull finish.
  • The underside of the watermelon should have a cream or yellow color.
  • The watermelon should be firm but not hard.
  • When tapped, the watermelon should make a hollow sound.

If you are unsure whether or not a watermelon is ripe, it is best to err on the side of caution and wait a few more days.


Watermelon growing stages take us on a captivating journey from tiny seeds to luscious fruits. From selecting quality seeds and nurturing seedlings to tending to the vines and enjoying a bountiful harvest, each stage is essential for successful watermelon cultivation.

By understanding the intricacies of watermelon growth and implementing proper care techniques, you can savor the sweet rewards of your efforts. So, the next time you bite into a delicious watermelon, remember the journey it undertook to reach your plate. Happy growing and happy harvesting!
