How to Grow Sugar Baby Watermelon in a Small Garden in a Raised Bed or Container

Choosing the Right Variety
Selecting the appropriate watermelon variety adapted to Pennsylvania's climate is crucial for a successful crop. Factors like days to maturity, disease resistance, and fruit size should be carefully considered. Here's a table comparing some popular watermelon varieties suitable for Pennsylvania:
VarietyDays to MaturityDisease ResistanceFruit Size
Sugar Baby | 75-85 days | Anthracnose, Fusarium Wilt | 6-12 lbs |
Crimson Sweet | 85-90 days | Anthracnose, Fusarium Wilt | 16-25 lbs |
Charleston Gray | 90-100 days | Anthracnose, Fusarium Wilt | 20-30 lbs |
Moon and Stars | 95-100 days | Anthracnose | 15-25 lbs |
Selecting varieties with shorter maturity periods is essential to ensure a successful harvest before Pennsylvania's growing season ends. Additionally, disease-resistant varieties can help combat common watermelon diseases in the region.
Days to Maturity
Pennsylvania's growing season typically lasts from late spring to early fall, making it crucial to choose watermelon varieties that can mature within this timeframe. Varieties like Sugar Baby and Crimson Sweet, which mature in 75-90 days, are well-suited for Pennsylvania's climate. Longer-maturing varieties may struggle to fully ripen before frost sets in.
Disease Resistance
Watermelons are susceptible to various diseases, and choosing disease-resistant varieties can help mitigate potential issues. Common watermelon diseases in Pennsylvania include anthracnose, fusarium wilt, and bacterial fruit blotch. Opt for varieties specifically bred for resistance against these diseases to ensure a healthy crop.
Site Selection and Preparation
Proper site selection and preparation are essential for successful watermelon cultivation in Pennsylvania. Watermelons thrive in well-drained, fertile soil and require ample sunlight to produce their signature sweet fruits.
Watermelons prefer slightly acidic soil with a pH range of 6.0 to 6.8. Before planting, test your soil and amend it with compost, aged manure, or other organic matter to improve fertility and drainage. Additionally, consider incorporating a balanced fertilizer like 10-10-10 into the soil to provide essential nutrients for plant growth.
Soil Requirements

Watermelons require well-draining soil rich in organic matter and nutrients. Aim for a soil pH between 6.0 and 6.8, which can be adjusted with lime or sulfur amendments if necessary. Incorporate aged compost or well-rotted manure into the soil to improve its structure and fertility.
Sunlight Needs
Watermelons are sun-loving plants and require at least 8 hours of direct sunlight per day for optimal growth and fruit production. Choose a planting site that receives full sun exposure throughout the day. If your garden area is partially shaded, consider building raised beds or using row covers to maximize sunlight exposure.
Planting and Care
Proper planting techniques and attentive care are vital for successful watermelon cultivation in Pennsylvania. Follow these guidelines for planting and maintaining your watermelon crop:
Watermelons can be grown from seeds or transplants. Direct seeding is more common, but transplanting can give the plants an early start, especially in regions with shorter growing seasons like Pennsylvania.
Direct Seeding vs. Transplanting
Direct seeding involves planting watermelon seeds directly into the prepared garden soil after the last frost date. This method is more straightforward but may result in a slightly later harvest compared to transplanting.
Transplanting involves starting watermelon seeds indoors 4-6 weeks before the last frost date. Once the seedlings have developed their first true leaves and the soil has warmed up sufficiently, they can be transplanted into the garden. This method can give watermelons an early start, but transplants require extra care during the transition to the outdoor environment.
Watering Needs
Watermelons have high water requirements, especially during fruit development. Ensure the soil remains consistently moist but not waterlogged. Water deeply, about 1-2 inches per week, and avoid wetting the leaves and vines to prevent disease. Mulching around the plants can help retain soil moisture and suppress weeds.

Fertilization
In addition to amending the soil before planting, watermelons benefit from regular fertilization throughout the growing season. Apply a balanced fertilizer, such as 10-10-10 or a slow-release organic fertilizer, when the vines begin to run. Follow up with additional applications every 4-6 weeks, being careful not to over-fertilize, which can lead to excessive vine growth and reduce fruit production.
Pest and Disease Management
Like any crop, watermelons are susceptible to various pests and diseases that can impact their growth and yield. While disease-resistant varieties can help mitigate some issues, it's essential to monitor your plants and implement preventative and control measures when necessary.
Here are some common pests and diseases to watch out for when growing watermelons in Pennsylvania:
- Pests:
- Aphids
- Cucumber beetles
- Squash bugs
- Squash vine borers
- Diseases:
- Anthracnose
- Fusarium wilt
- Bacterial fruit blotch
- Powdery mildew
Common Pests and Diseases

- Aphids: These small, pear-shaped insects can cluster on the undersides of leaves and stems, feeding on plant sap and potentially transmitting viruses. Control methods include insecticidal soaps, horticultural oils, or introducing beneficial insects like ladybugs.
- Cucumber Beetles: These yellow-and-black striped beetles can damage watermelon plants by feeding on leaves, stems, and fruits. Floating row covers, sticky traps, or insecticides may be necessary for control.
- Anthracnose: A fungal disease that causes circular, sunken lesions on leaves, stems, and fruits. Preventative measures include using resistant varieties, crop rotation, and fungicide applications.
- Fusarium Wilt: A soil-borne fungal disease that causes wilting and eventual plant death. Choosing resistant varieties and practicing good sanitation are essential for control.
- Bacterial Fruit Blotch: This bacterial disease results in dark, sunken lesions on watermelon fruits, making them unmarketable. Copper-based fungicides, crop rotation, and removing infected fruits can help manage this disease.
Implementing an integrated pest management (IPM) approach, combining cultural, physical, and chemical control methods, is recommended for effective pest and disease management in watermelon cultivation.
Harvesting and Storage
Knowing when to harvest and properly handling watermelons is crucial for enjoying their peak flavor and extending their shelf life. Here are some tips for successful watermelon harvesting and storage:
Ripeness Indicators
Several visual and tactile cues can help determine when watermelons are ripe and ready for harvest:
- The underside of the melon, where it rests on the ground, should have a cream or yellow color (not white or green).
- The tendril closest to the melon should be dry and brown.
- The rind should be dull green, not shiny or glossy.
- When tapped, a ripe watermelon will produce a dull, hollow sound.
Handling and Storage
Proper handling and storage techniques can extend the shelf life of your harvested watermelons:
- Use a sharp knife or pruners to cut the melon from the vine, leaving a few inches of stem attached.
- Avoid carrying watermelons by the stem, as it can break off and cause the melon to spoil faster.
- Store harvested watermelons in a cool, shaded area or refrigerator until ready for consumption.
- Whole, uncut watermelons can last up to 2-3 weeks when stored at temperatures between 50-60°F (10-15°C).
- Once cut, watermelons should be consumed within 3-5 days for optimal freshness and flavor.
Conclusion
Growing watermelons in Pennsylvania can be a rewarding experience, providing you with fresh, juicy fruits perfect for summer enjoyment.
