Introduction to watermelons
Brief history and origin of watermelons
Watermelons likely originated in southern Africa, where evidence of their cultivation has been found dating back to the 2nd millennium BCE. From there, they spread north through Egypt and the Mediterranean. Today China is the world’s largest producer of watermelons. Other top producers include Turkey, Iran, Brazil, and the United States.
Importance and nutritional benefits of watermelons
Watermelons are an important food crop around the world due to their nutritional content and hydrating properties. The flesh provides significant levels of vitamins A, B6, and C, as well as lycopene, potassium, and antioxidants. Watermelons are also over 90% water, making them ideal for hydration on hot summer days. Growing your own watermelons can provide your family with a tasty and nutritious addition to your diet.
Overview of watermelon production globally
| Country | Annual Production (million tonnes) |
| China | 79.2 |
| Turkey | 4.3 |
| Iran | 4.2 |
| Brazil | 2.5 |
| United States | 2.3 |
Getting Started with Watermelons
Before planting your first watermelon seeds, some advance planning and preparation is required. In this chapter we’ll cover optimal planting times, soil testing, site selection, and how to choose the right watermelon variety for your region.
Pre-Planting Considerations
- Planting times: Ideal planting dates range from early spring in warm climates to early summer in cooler regions. Consult local guides for your first and last frost dates.
- Soil testing: Test your soil to determine pH and nutrient levels. Watermelons prefer slightly acidic soil (pH 6.0-6.8) with moderate fertility.
- Site selection: Choose a site with full sun, good drainage, and shelter from strong winds. Rotating sites yearly helps prevent disease.
Optimal planting times by region
| Region | Planting Window |
| Southeast | March to early May |
| Midwest | Late May to mid June |
| Northeast | Late May to mid June |
| West Coast | Early April to mid May |
Soil testing and preparation
- Use a soil test kit or send samples to a lab to determine:
- pH
- Macronutrient levels (N,P,K)
- Micronutrient levels
- Organic matter percentage
- Adjust pH with lime (to raise) or sulfur (to lower) based on test
- Improve drainage if needed
- Add compost or manure 1-2 weeks before planting
Site selection for planting
- Full sun: At least 6 hours daily
- Fertile, well-draining soil
- Avoid windswept areas using windbreaks
- Rotate planting sites yearly to prevent disease
- Allow ample space for vines to spread
Selecting Watermelon Varieties
Choosing the right watermelon variety for your growing conditions is key to success. Consider the following factors:
Comparison of watermelon varieties
| Variety | Description | Good For |
| Icebox | Small, round fruits (5-15 lbs) | Small gardens, short seasons |
| Jubilee | Large, oblong striped fruits (15-30 lbs) | Warm climates, home gardens |
| Crimson Sweet | Medium-large fruits (15-25 lbs) | Wide climatic adaptability |
| Moon and Stars | Variegated rind, sweet pink flesh | Novelty, heirloom appeal |
Varietal recommendations for specific climates
- Cool climates: Early ripening, smaller varieties like Sugar Baby
- Warm climates: Big Carolina, Crimson Sweet, Jubilee
- Short growing seasons: Icebox types
Choosing seeds vs. transplants
- Seeds: Less expensive, more variety, better adapted
- Transplants: Faster maturation, avoid cold damage
Use transplants where seasons are very short. Otherwise, start from seed.
The Life Cycle of a Watermelon
Now that your site is prepared and varieties selected, it’s time to learn about the phases of watermelon growth from seed to harvest. Here’s an overview of the watermelon life cycle.
Overview of the Life Cycle
Watermelons progress through four key phases:
- Germination – Seed sprouts and seedling emerges
- Vegetative growth – Leaves, vines, and roots expand
- Flowering – Flowers emerge and pollination occurs
- Fruit development – Pollinated flowers form expanding fruits
Detailed Growth Stages
Let’s look more closely at what happens during each stage of the life cycle:
Seeds
- Purchase disease-free seeds from reputable source
- Start indoors 3-4 weeks before planting out
Germination
- Sprout occurs 3-10 days after sowing
- Seedlings emerge 5-14 days after
- Develop 2-3 true leaves before transplanting
Vegetative Growth
- Vines lengthen rapidly
- Leaves expand to capture sunlight
- Roots spread widely to absorb water and nutrients
Flower Production and Pollination
- Male and female flowers form on same plants
- Bees transfer pollen between flowers
- Fruits develop from pollinated female flowers
Fruit Development and Ripening
- Fruits grow rapidly in warm weather
- Gradually change color as sugars develop
- Ripening occurs 20-50 days after pollination
Harvesting
- Indicators: dried tendrils, yellow belly spot
- Use a sharp knife to cut from vine
- Leave 3-4 inches of stem attached
Watermelon Plant Timeline
| Stage | Timeline |
| Germination | 3-14 days after sowing |
| Transplanting | 2-3 true leaves emerged |
| Vegetative Growth | 4-5 weeks after transplant |
| Flowering | 6-8 weeks after transplant |
| Fruit Set | 1-2 weeks after flowering |
| Ripening | 3-5 weeks after fruit set |
| Harvest | 20-50 days after pollination |
Best Practices for Watermelon Cultivation
Now that you understand the phases of watermelon growth, let’s look at some key best practices to help your plants thrive.
Conditions for Growing Watermelon
Watermelons need:
- Warm weather
- Lots of sunshine
- Plentiful moisture
- Good drainage
- Shelter from wind
- Bees for pollination
- Periodic fertilizing
Integrated Pest Management (IPM)
IPM combines preventive measures and organic/chemical controls:
- Crop rotation to prevent disease buildup
- Row covers to exclude pests
- Natural predators like ladybugs to eat aphids
- Organic sprays derived from plants
- Pesticides carefully applied only when needed
The goal is to maximize natural defenses before using chemical controls.
Pollination
Bees play a critical role in watermelon pollination. Follow these tips:
- Avoid applying pesticides during flowering stage
- Create bee habitat in nearby areas
- Consider bee-attracting companion plants like marigolds, zinnias, etc.
- As a last resort, manually pollinate using a cotton swab
Seasonal Care and Challenges
Proper care throughout the seasons gives your watermelons the best chance for abundant harvests. Here are some key tips.
Watermelon Plant Care Throughout the Seasons
Spring:
- Apply nitrogen fertilizer to promote vegetative growth
- Use floating row covers to prevent insect damage
- Provide temporary shade if temperatures exceed 90°F
Summer:
- Water 1-2 inches per week with drip irrigation
- Side dress with nitrogen fertilizer
- Scout for pests and diseases
- Pollinate flowers by attracting bees
Fall:
- Reduce watering as fruits ripen
- Watch fruits for ripeness indicators
- Harvest promptly once ripe to prevent splitting
Watermelon Cultivation Challenges
Watermelons can face various challenges depending on your region:
| Region | Common Challenges |
| Southeast | Disease pressure, heavy rainfall |
| Midwest | Short seasons, cool temperatures |
| Northeast | Short seasons, pest damage |
| West Coast | Insufficient water, high temperatures |
Solutions may include: using disease-resistant varieties, season extension techniques, irrigation, and pest management practices. Consult local growing guides for specific recommendations.
Sustainability Practices
Consider these tips for environmentally sustainable watermelon growing:
- Water conservation: Use drip irrigation, mulch to reduce evaporation, reduce watering once established
- Sustainable pest management: Emphasize preventive measures first before chemical controls
Harvesting, Post-Harvest Handling, and Uses
Let’s cover how and when to harvest watermelons, plus storage and usage once they make it to your kitchen.
When and How to Harvest Watermelons
- Look for these ripeness indicators:
- Curled, dried tendril nearest fruit
- Yellowish belly spot where fruit touched ground
- Hollow, dull thud when thumped
- Use a sharp knife to sever the vine a few inches beyond the fruit
- Leave 3-4 inches of stem attached to fruit
- Harvest in early morning when coolest
Post-Harvest Handling
- Curing: Leave harvested melons laying in the sun for 5-7 days to further ripen sugars
- Cleaning: Wash well, scrubbing gently with vegetable brush
- Storage: Whole, uncut melons can keep 2-3 weeks at 60-70°F
- Refrigerate cut melons wrapped in plastic for up to 5 days
