Choosing the Right Watermelon Variety
First things first, let’s talk about watermelon varieties. Not all watermelons are created equal, and some are better suited for certain climates and garden sizes than others.
* Consider your climate: If you live in a cooler climate with a shorter growing season, you’ll want to choose a variety that matures quickly. Look for varieties like ‘Sugar Baby’ (my personal favorite for smaller gardens and quick harvests!), ‘Bush Sugar Baby’, or ‘Golden Midget’. If you have a longer, warmer growing season, you can experiment with larger varieties like ‘Charleston Gray’ or ‘Crimson Sweet’.
* Think about space: Watermelons need room to sprawl. If you have a small garden, consider bush varieties like ‘Bush Sugar Baby’ or growing your watermelons vertically on a trellis (more on that later!).
* Flavor preferences: Do you prefer a super sweet watermelon, or something with a bit more tang? Read descriptions of different varieties to find one that suits your taste. ‘Black Diamond’ is known for its intense sweetness, while ‘Jubilee’ has a slightly more complex flavor.
* Seedless vs. Seeded: Seedless watermelons are convenient, but they can be a bit more challenging to grow. They require a pollinator variety nearby to produce fruit. Seeded watermelons are generally easier for beginners.
Preparing Your Garden Bed
Watermelons are heavy feeders, meaning they need a lot of nutrients to thrive. Proper soil preparation is key to a successful harvest.
* Sunlight is crucial: Watermelons need at least 6-8 hours of direct sunlight per day. Choose a location in your garden that gets plenty of sun.
* Soil type: Watermelons prefer well-drained, sandy loam soil. If your soil is heavy clay, you’ll need to amend it with organic matter like compost or well-rotted manure.
* Soil pH: The ideal soil pH for watermelons is between 6.0 and 6.8. You can test your soil pH with a soil testing kit from your local garden center. If your soil is too acidic, you can add lime to raise the pH. If it’s too alkaline, you can add sulfur to lower the pH.
* Amending the soil: Dig a generous amount of compost or well-rotted manure into your garden bed. This will improve drainage, add nutrients, and help retain moisture. I usually add about 4-6 inches of compost to my watermelon bed.
* Fertilizing: Watermelons benefit from a balanced fertilizer. I like to use a slow-release fertilizer with an NPK ratio of 10-10-10 or 14-14-14. Follow the instructions on the fertilizer package for application rates.
Starting Your Watermelon Seeds
You can either start your watermelon seeds indoors or direct sow them in your garden. Starting them indoors gives you a head start, especially if you have a short growing season.
* Starting seeds indoors:
1. Timing: Start your seeds about 4-6 weeks before the last expected frost in your area.
2. Containers: Use peat pots or biodegradable pots to avoid disturbing the roots when transplanting. Watermelon roots are sensitive, and transplant shock can stunt their growth.
3. Soil: Use a seed-starting mix.
4. Planting: Plant the seeds about 1 inch deep.
5. Watering: Keep the soil moist but not soggy.
6. Warmth: Watermelon seeds need warmth to germinate. Use a heat mat to keep the soil temperature between 70-80°F (21-27°C).
7. Light: Once the seedlings emerge, provide them with plenty of light. A sunny windowsill or grow lights will work.
8. Hardening off: Before transplanting your seedlings outdoors, you’ll need to harden them off. This means gradually exposing them to outdoor conditions over a period of 7-10 days. Start by placing them in a sheltered location for a few hours each day, gradually increasing the amount of time they spend outdoors.
* Direct sowing seeds:
1. Timing: Direct sow your seeds after the last expected frost when the soil temperature is at least 70°F (21°C).
2. Planting: Plant the seeds about 1 inch deep and space them according to the variety’s recommendations.
3. Watering: Keep the soil moist until the seeds germinate.
4. Thinning: Once the seedlings emerge, thin them to the strongest plant per hill.
Transplanting Watermelon Seedlings
If you started your seeds indoors, it’s time to transplant them into your garden.
1. Choose a cloudy day: Transplanting on a cloudy day will help reduce transplant shock.
2. Prepare the planting holes: Dig holes that are slightly larger than the peat pots. Space the holes according to the variety’s recommendations.
3. Carefully remove the seedlings from the pots: If you’re using peat pots, you can plant the entire pot. If you’re using other types of pots, gently remove the seedlings, being careful not to damage the roots.
4. Plant the seedlings: Place the seedlings in the holes and backfill with soil.
5. Water thoroughly: Water the seedlings well after transplanting.
6. Mulch: Apply a layer of mulch around the plants to help retain moisture and suppress weeds. I like to use straw or wood chips.
Caring for Your Watermelon Plants
Now that your watermelon plants are in the ground, it’s time to give them the care they need to thrive.
* Watering: Watermelons need consistent moisture, especially during fruit development. Water deeply and regularly, especially during dry spells. Avoid overhead watering, as this can promote fungal diseases. Drip irrigation is ideal.
* Fertilizing: Side-dress your watermelon plants with a balanced fertilizer every 2-3 weeks. You can also use a liquid fertilizer like fish emulsion or seaweed extract.
* Weeding: Keep your watermelon bed free of weeds. Weeds compete with watermelons for nutrients and water.
* Pest control: Watermelons can be susceptible to pests like aphids, squash bugs, and cucumber beetles. Inspect your plants regularly and take action if you see any pests. Insecticidal soap or neem oil can be effective for controlling many common pests.
* Pollination: Watermelons need to be pollinated to produce fruit. Bees are the primary pollinators. If you’re not seeing many bees in your garden, you can hand-pollinate your watermelons. To hand-pollinate, use a small paintbrush to transfer pollen from the male flowers to the female flowers. Female flowers have a small swelling at the base of the flower (the developing watermelon).
* Pruning: While not strictly necessary, pruning can help improve air circulation and reduce the risk of fungal diseases. Remove any dead or yellowing leaves. You can also prune some of the lateral vines to encourage the plant to focus its energy on fruit production.
* Supporting the fruit: As your watermelons grow, they may need support to prevent them from rotting on the ground. You can use a sling made from pantyhose or burlap to support the fruit. For smaller varieties, you can also grow them on a trellis.
Growing Watermelons Vertically on a Trellis
If you’re short on space, growing watermelons vertically on a trellis is a great option.
1. Choose a sturdy trellis: Watermelons can get heavy, so you’ll need a strong trellis that can support the weight of the fruit.
2. Plant your watermelon seedlings near the trellis: Space the seedlings about 12-18 inches apart.
3. Train the vines to climb the trellis: As the vines grow, gently guide them up the trellis and tie them in place with twine or plant ties.
4. Support the fruit: As the watermelons develop, you’ll need to support them with slings. Make slings from pantyhose, burlap, or netting and attach them to the trellis.
5. Water and fertilize regularly: Watermelons grown on a trellis need the same care as watermelons grown on the ground.

Frequently Asked Questions
What is the best time to start growing watermelons?
The ideal time to start growing watermelons depends on your climate and the length of your growing season. In general, watermelons require a long, warm growing season of at least 70-85 days. If you live in a region with a short growing season, it’s best to start your watermelon seeds indoors 4-6 weeks before the last expected frost. This will give your seedlings a head start and allow them to mature in time for harvest. If you live in a warmer climate with a longer growing season, you can direct sow your watermelon seeds outdoors once the soil has warmed up to at least 70 degrees Fahrenheit. Be sure to check your local weather forecast and adjust your planting schedule accordingly.
How much space do watermelons need to grow?
Watermelons are sprawling plants that require a significant amount of space to grow. As a general rule, you should allow at least 4-6 feet between watermelon plants and 8-10 feet between rows. If you’re growing watermelons on a trellis, you can reduce the spacing slightly, but be sure to provide adequate support for the heavy fruits. Consider the mature size of the watermelon variety you’re growing when determining spacing. Larger varieties will require more space than smaller, personal-sized varieties. Proper spacing is essential for ensuring adequate sunlight exposure, air circulation, and nutrient availability.
What kind of soil is best for growing watermelons?
Watermelons thrive in well-drained, sandy loam soil that is rich in organic matter. The soil should have a pH between 6.0 and 6.8. Before planting, amend the soil with compost, aged manure, or other organic materials to improve drainage, fertility, and water retention. Avoid heavy clay soils, as they can become waterlogged and inhibit root growth. If you have clay soil, consider growing your watermelons in raised beds or containers. Perform a soil test to determine the nutrient levels and pH of your soil. Amend the soil as needed based on the test results.
How often should I water my watermelons?
Watermelons require consistent moisture, especially during the early stages of growth and fruit development. Water deeply and regularly, aiming to keep the soil consistently moist but not waterlogged. Water at the base of the plants to avoid wetting the foliage, which can increase the risk of fungal diseases. During hot, dry weather, you may need to water your watermelons daily. As the fruits begin to ripen, you can reduce watering slightly to improve their sweetness. Use a moisture meter to monitor the soil moisture levels and adjust your watering schedule accordingly.
What are some common pests and diseases that affect watermelons?
Watermelons are susceptible to a variety of pests and diseases, including aphids, squash bugs, vine borers, powdery mildew, and fusarium wilt. Regularly inspect your plants for signs of infestation or disease. Use organic pest control methods, such as insecticidal soap or neem oil, to control aphids and squash bugs. Wrap the base of the watermelon vines with aluminum foil to deter vine borers. Improve air circulation and avoid overhead watering to prevent powdery mildew. Choose disease-resistant watermelon varieties to minimize the risk of fusarium wilt. Practice crop rotation to prevent soilborne diseases from building up in your garden.
How do I know when my watermelons are ripe?
Determining when a watermelon is ripe can be tricky, but there are several indicators to look for. The most reliable sign is the color of the ground spot, which is the area of the watermelon that rests on the ground. When the watermelon is ripe, the ground spot will turn from white or pale green to a creamy yellow or orange color. Other indicators include a dull thud when you tap the watermelon, a dry and brown tendril closest to the fruit, and a slight give when you press on the blossom end of the watermelon. With practice, you’ll develop a feel for when your watermelons are perfectly ripe.
Can I grow watermelons in containers?
Yes, you can grow watermelons in containers, but you’ll need to choose a large container that is at least 24 inches in diameter and 24 inches deep. Use a high-quality potting mix that is well-draining and rich in organic matter. Choose a compact or bush-type watermelon variety that is well-suited for container growing. Provide adequate support for the vines, such as a trellis or stake. Water regularly and fertilize every 2-3 weeks with a balanced fertilizer. Place the container in a sunny location that receives at least 6-8 hours of direct sunlight per day. Container-grown watermelons may require more frequent watering and fertilization than those grown in the ground.
