Simple Guide To Growing Watermelons In Containers

Watermelons can be grown in containers if you have a small garden. Container watermelons are possible and enjoyable whether you are undertaking balcony gardening or simply seeking a better way to use your limited space.

It only takes a little information to figure out how to produce watermelons in containers properly.

History Of Watermelon

History & Origin Of Watermelons

Important findings in northeastern Africa, archeological relics of watermelons, chiefly seeds, dating back 5,000 years, have been discovered.

In an Egyptian tomb dating back at least 4,000 years, a depiction of a huge, striped, rectangular fruit on a platter was found.

In the first century CE, the Greek word pepon, Latin pepo, and Hebrew avattiah were all used to refer to the same enormous, thick-rinded, wet fruit, the watermelon.

Watermelons are depicted with three sweet fruits: figs, table grapes, and pomegranates in Hebrew literature from the end of the second century CE and Latin literature from the beginning of the sixth century CE.

Sudan and its neighbouring nations in northeastern Africa have regularly seen wild and primitive watermelons.

9 Best Types Of Watermelons For Containers

For growing Watermelons in containers, you should know all varieties fitted for containers.

Watermelons come in over 500 different types, all of which may be successfully grown in containers if you follow the appropriate directions. The following are the most popular types for growing in pots:

Early Moonbeam Watermelon

1. Early Moonbeam Watermelons

It’s a great variety for container gardening. From 5 to 8 pounds, yellow-fleshed with a thin rind.

For northern climates, this is one of the best melons. This sweet, early, and productive watermelon will add flavour to your summer.

Bush Sugar Baby Watermelon

‘Golden Midget' is a little watermelon type to make your melon patch stand out. When fully ripe, the rinds of this open-pollinated cultivar become yellow, making harvesting a breeze.

The round fruits are tiny, weighing only three pounds each, and have lovely pink flesh with black seeds.

‘Golden Midget' is an extremely early cultivar ideal for short-season producers, with fruit ripe in only 70 days.

Jade Star Watermelon

5. Jade Star Watermelon

Ninety days after seeding, ‘Jade Star' is usually ready for harvest. Each plant produces 3 to 4 fifteen-pound melons. Oval or round fruits with dark green rinds and bright scarlet flesh. Warm areas are ideal for watermelons.

Millennium Watermelon

6. Millennium Watermelon

Millennium is gorgeous on the outside with its rich rind pattern that resists fading in the sun, but it also has a dark crimson inside and exceptional meat quality.

Millennium is an early maturing variety with very consistent size and shape. Fruit sizes range from 12 to 15 pounds and are produced on a robust vine.

7. Moon And Stars Watermelon

While the size of the Moon and Stars watermelon varies based on type, it is normally a large and heavy watermelon, weighing up to 50 pounds in some situations.

The dark green fruits are dotted with various-sized yellow spots, giving them a night sky appearance.

The Moon and Stars watermelon is available throughout the summer and has red, pink-red, or yellow flesh, depending on the type.

8. Solitaire Watermelon

Mini, seedless, round varieties, measuring 3½ to 5 lbs. each, are larger than a softball but smaller than a soccer ball.

The flesh is a deep crimson colour and is crisp and delicious. This is an excellent choice for places with a short growing season.

Jubilee Watermelon

9. Jubilee Watermelon

The Jubilee Watermelon was developed in 1963 at the Florida Agricultural Experiment Station as an open-pollinated variety. Watermelons can be planted directly or transplanted.

We recommend putting seeds every 12′′ along the intended row to guarantee a good stand when direct sowing.

Plants should be thinned to one every two feet once they have emerged. It takes 95 days to reach maturity.

11 Steps Of Growing Watermelons In Containers

Choosing A Container

Step 1: Choosing A Container

The 1st step in growing Watermelons in containers is to select the right pot. Watermelons in pots are not difficult to grow, although they can be tough.

You must grasp the fundamentals. Watermelons require a deep container due to their extensive taproot.

It will be necessary to use a large pot or bucket with a depth of at least 2 feet and a width of at least half a foot.

Prepare Soil

Step 2: Prepare Soil

Aside from container size and variety selection, the soil is the most crucial component in producing container watermelons.

It's critical to use the correct soil blend in the container; otherwise, you'll be tethered to your garden hose or watering can all summer.

Using a well-draining mix will dry up too rapidly, affecting plant health and fruit output. If you choose a combination that isn't well-draining enough, the soil will remain wet, depriving the roots of oxygen and perhaps causing root rot.

Watermelons are heavy feeders who dislike being exposed to the elements. Choose a good potting mix and combine it with compost. I make a half-and-half mix of organic potting soil and finished compost.

The potting soil keeps the mix light and well-draining, while the compost absorbs and holds water. In addition, the compost provides nutrients and helpful soil bacteria to the container.


Step 3: Planting

It is strongly advised that you start your watermelons from seeds. These lovely fruits have a sensitive root structure that isn't fond of being transplanted.

Transferring your plant may cause it to become stressed. Watermelon seeds should not be planted in more than three pots at a time.

Watermelons should be planted between the end of the winter and the beginning of spring. It normally takes 6 to 10 days for the seeds to germinate.

Once the seedlings are visible above the soil's surface, thin out the weak ones and leave just the strongest.

Step 4: Pollinate By Hand

On the same vine, watermelon plants produce both female and male blooms. Pollinators like bees and butterflies will naturally pollinate the plants, but a little more aid from you in hand pollination will increase the possibilities of fruit formation.

Locating A Sunny Area

Step 5: Locating A Sunny Area

Find a sunny area that is out of the way of severe winds and has easy access to water. Because the pot will be heavy and difficult to move once you've added soil, place it in this location while it's still empty.


Step 6: Supporting

The watermelon plant needs to be supported as well. You may use a trellis or some sticks for this. In either case, be sure your support can support the weight of melons without breaking.

At least 4 feet tall is required for the trellis or sticks. Use a stretchy material like pantyhose or a T-shirt to form a hammock under the fruits as they grow. This will help them grow and keep them from snapping off the vine as they get bigger.


Step 7: Watering

Proper watering is one of the most important parts of container growing watermelons. Because watermelons demand a lot of water, it's critical to maintain the soil evenly moist–but not wet–at all times, and the water must drain easily from the bottom.

Water your watermelon plant daily if you're growing it in a container and twice if it's hot. Reduce the watering after the fruits begin to expand and mature.

During this time, water slowly and gently. To get the sweetest melons, avoid overwatering and underwatering.

Step 8: Temperature

Warmth is a favourite of watermelons. Tropical climates are ideal for growing them. They may, however, grow in moderate climates. The optimal temperature for growing watermelons is between 65° and 85°F (18°-30°C).

You may also grow them from 50 to 95 degrees Fahrenheit (10-35 C). Your fruits, on the other hand, will be tasteless if the temperature drops below 50 degrees Fahrenheit.

Step 9: Fertilize

You should Fertilize for growing watermelons in containers. Begin fertilizing the plant with a full-spectrum liquid fertilizer.

Use a fertilizer with less nitrogen as the plant begins to flower and appear to set fruit. Consider using a liquid seaweed fertilizer.


Step 10: Pruning

Allow only the main vine to develop to ensure a healthy and fruitful plant. Remove side branches when the plant is young to prevent them from growing more. Remove any stems that are broken or unhealthy as well.

Step 11: Harvesting

When the watermelon is fully ripe, it should be harvested. Watermelons are harvested 65-90 days after planting or 30-50 days after flowering.

  • When you scratch the skin with your nails, it's a good sign that they're ready to harvest.
  • It's time to pick your fruit if it separates immediately away.
  • The base spot, or the area that comes into contact with the ground, transforms from white to cream.
  • The pedicel or stalk that connects the mother plant to the child plant will be dry.
  • Depending on the cultivar, the watermelon will be ready to harvest 65 to 90 days after planting.
  • The tendrils of the vine turn yellow and die when the watermelon is ready to be harvested.
  • The watermelons are still immature if the tendrils are green.
  • When you tap a ripe watermelon, it makes a dull, hollow sound.
  • The fruit will transform from white to yellow on the soil side, indicating it is ready to harvest.
  • The end of the stem of a ripe melon usually has a delicious scent.

To harvest the watermelon, you must cut it off the vine using a sharp knife or garden trimmer. It's that simple.

Diseases & Pests Of Watermelons

1. Bacterial Fruit Blotch

Seedlings, young plants, and fruits with water-soaked areas that spread and become necrotic are frequently caused by the bacterium Acidovorax avenae subspecies citrulli.

The leaves may become brown, but the fruit is the most visible symptom. The rind may fracture and spill a sticky yellow substance.

If a copper fungicide is given as soon as indications of bacterial fruit blotch are discovered, symptoms can be controlled.

2. Anthracnose

This seed-borne fungus can be difficult to see because it appears as little spots on your plants and fruits.

As they mature, these spots enlarge and turn black or gray, and additional recessed regions on your fruit may appear.

Crop rotation and a neem oil treatment will help protect this and future harvests from anthracnose.

3. Gummy Stem Blight 

When the gummy stem blight fungus is present, older tissues are harmed more frequently than fresh ones.

The first indicators of disease are black, wrinkled spots on leaves and dark or sunken areas on stems and fruits.

Affected plants quickly collapse in humid or rainy conditions. Controlling gummy stem blight is tough, although copper fungicides can help if administered as soon as it emerges.

4. Powdery Mildew

Powdery mildew, one of the most frequent plant diseases, does not spare watermelons. When the illness is active, leaves appear to have a white powdery substance, though fruits are usually unaffected.

Leaves darken and die as the powdery mildew spreads across the plant, exposing fruits to sunburn and weakening the plant.

Although neem oil is a wonderful remedy, trimming your watermelon plant to increase air circulation can be just as effective.

5. Downy Mildew 

The angular leaf patches created by downy mildew as it works through watermelon leaves are distinctive.

On the undersides of infected leaves, they may begin as yellow spots, but they quickly turn brown with purple spores.

Downy mildew won't harm your fruit but will weaken your plants, reducing production. This noxious mildew can be controlled with neem oil.

Extra Helpful Tips for Growing Watermelons In Containers

  • Start the seeds indoors or in a greenhouse in mild and short summer regions as soon as possible, immediately in a container or a biodegradable pot.
  • Watermelons are heavy feeders that use many organic materials when growing them in containers. Every 3-4 weeks, apply manure or compost to the side of your potted melon plant. If there isn't enough room in the container, scrape and remove the topsoil.
  • Stress to the plant during fruit maturation (changes in temperature, pests and diseases, overwatering, and lack of water) leads to less flavorful and sweet fruits.
  • Growing melons vertically on a trellis is a terrific way to save limited space. Make a hammock out of netting, a bag, or a flexible cloth to support the fruit.
  • Allowing the plant to set up too many fruits is the key to getting the best quality. For large fruit kinds, 2-4 fruits are sufficient at a time, while 4-6 fruits are suitable for smaller varieties.
  • Plant in a series for consistent harvests. Plant 2-4 plants and repeat in two weeks.
