Discover the Ultimate Guide to Growing Watermelon in Pots from Seed – You Won’t Believe How Easy It Is!

Growing your own watermelon might seem like a feat reserved for sprawling gardens, but it’s surprisingly achievable even with limited space. Learning how to grow watermelon in pots from seed opens up a world of juicy, refreshing fruit right on your patio or balcony. This guide will walk you through the process, from selecting the right seeds to harvesting your own sweet summer treat.

1. Choosing the Right Watermelon Variety

The first step to growing watermelon in pots is selecting the right variety. Not all watermelons are created equal, and some are better suited for container gardening than others. Look for compact, bush-type varieties that are specifically bred for pots. These varieties typically produce smaller watermelons, but they’re still delicious and perfect for enjoying with friends and family.
Here are a few popular compact watermelon varieties:

• Sugar Baby: This classic choice is known for its sweet flavor and small, round fruit.
• Blacktail Mountain: This variety boasts a deep red flesh and a sweet, juicy flavor.
• Golden Midget: This unique watermelon features a golden yellow flesh and a sweeter taste than traditional varieties.
• Yellow Doll: Another yellow-fleshed variety, Yellow Doll is compact and produces small, round watermelons.

2. Starting Watermelon Seeds Indoors

Watermelon seeds need warm soil to germinate, so starting them indoors is a good way to give them a head start. Here’s how:

• Choose the right pot: Select a pot that is at least 12 inches in diameter and has drainage holes.
• Fill the pot with seed starting mix: This type of soil is specifically formulated for starting seeds and provides the ideal environment for germination.
• Plant the seeds: Plant two to three seeds per pot, spacing them about an inch apart. Cover the seeds with about a half-inch of soil.
• Water the seeds: Gently water the soil until it is moist but not soggy.
• Provide warmth: Watermelon seeds need warm soil to germinate, so place the pots in a sunny location or use a heat mat.
• Keep the soil moist: Water the seeds regularly, but avoid overwatering.
• Thin the seedlings: Once the seedlings have two sets of true leaves, thin them out to leave the strongest seedling in each pot.

3. Transplanting Your Watermelon Seedlings

Once your watermelon seedlings have developed a strong root system and are about 6 inches tall, it’s time to transplant them outdoors.

• Choose the right pot: Select a large pot that is at least 18 inches in diameter and has drainage holes. A 24-inch pot is ideal for growing watermelon in pots.
• Fill the pot with potting mix: Use a high-quality potting mix that is specifically formulated for vegetables.
• Prepare the pot: Before transplanting, water the pot thoroughly to ensure the soil is moist.
• Gently remove the seedling from its starting pot: Be careful not to damage the roots.
• Plant the seedling: Dig a hole in the center of the pot that is slightly wider and deeper than the seedling’s root ball. Place the seedling in the hole and backfill with soil, making sure the root ball is covered.
• Water the seedling: Water the seedling thoroughly after transplanting.

4. Providing the Right Sunlight and Watering

Watermelons are sun-loving plants, and they need at least six hours of direct sunlight per day to thrive. Choose a sunny spot for your pot, ideally facing south or west.
Watermelon plants need consistent moisture, but they don’t like to be waterlogged. Water deeply but infrequently, allowing the soil to dry out slightly between waterings.

5. Fertilizing Your Watermelon Plant

Watermelons are heavy feeders and require regular fertilization to produce abundant fruit. Use a balanced fertilizer specifically formulated for vegetables and apply it every two to three weeks throughout the growing season. Follow the fertilizer’s instructions for the appropriate dosage.

6. Supporting Your Watermelon Vine

As your watermelon vine grows, it will need support to prevent it from sprawling on the ground. You can use a trellis, tomato cage, or even a sturdy stake to provide support.

7. Harvesting Your Watermelon

Watermelons are typically ready to harvest about 80 to 100 days after planting. You can tell that a watermelon is ripe by:

• Sound: A ripe watermelon will have a dull, thudding sound when you tap it.
• Color: The underside of the watermelon will turn a creamy yellow color.
• Stem: The stem will dry out and detach easily.

Once you’ve harvested your watermelon, store it in a cool, dry place for up to two weeks.

Questions You May Have

Q: Can I grow watermelon in a smaller pot?
A: While smaller pots are possible, it’s best to use a pot that is at least 18 inches in diameter to ensure your watermelon has enough space to grow.
Q: What if my watermelon vine starts to wilt?
A: Wilting can be a sign of dehydration, so water your plant deeply. However, if the wilting persists, it could be a sign of root rot, which is often caused by overwatering.
Q: How do I prevent pests and diseases?
A: Inspect your plants regularly for any signs of pests or diseases. Use organic pest control methods to deter insects, and consider using a fungicide to prevent fungal diseases.
Q: Can I grow watermelon in a hanging basket?
A: While it’s possible to grow watermelon in a hanging basket, it’s not ideal. Watermelon vines can get quite heavy, and the weight could strain the basket. It’s best to use a sturdy pot that can support the plant’s weight.
