Starting Watermelons Indoors
In cities like Omaha (Zone 5b), begin indoor watermelon seed starting between April 1 and April 15. This timeline ensures healthy seedlings ready for outdoor transplantation starting from mid-May to early June once the risk of frost has passed.
Transplanting Watermelon Seedlings
Transplant watermelon seedlings outdoors from May 15 to June 1, ensuring the soil has warmed above 70°F consistently. Space the seedlings 24-36 inches apart in rows with at least 4-6 feet between rows for optimal growth.
General Care and Maintenance
Watering
- Provide consistent and deep watering to maintain evenly moist soil. Nebraska’s variable weather requires regular checks to ensure soil does not dry out, especially in hot periods.
- Water at the base of plants to avoid leaf wetness, reducing the risk of diseases.
Fertilizing
- Apply a balanced fertilizer during planting and when the first fruits start forming. Incorporating compost before planting can enhance soil fertility and structure.
Pest and Disease Management
- Regularly monitor for common pests like aphids, cucumber beetles, and powdery mildew. Vigilance is essential, especially during warm months.
- Implement organic or integrated pest management methods to protect watermelon plants from pests and diseases.
Harvesting
- Harvest watermelons when they reach the desired size and the underside turns creamy yellow. Regular harvesting promotes peak sweetness and quality.
The importance of good soil
Before starting to grow it is important to take a step back and find the condition of the soil in your garden,The optimal soil is a blend that includes the mineral-rich dirt along with organicrich organic matter that plants need to thrive.
In my garden I try to compost as mutch as possible, so I can mix in the nutrient ritch compost in my soil. I use both hot composting of food scraps and cold composting of all organic garden “waste”..
If you dont have the time or space for composting, it is possible to get compost ready to use in garden centers and Community Composting.
You can read more on Community Composting here: https://www.epa.gov/sustainable-management-food/community-composting
If you are uncertain of the quality of your soil, you can get easy to use soil tests at amazon for 17 dollars. Check latest prices here: Soil testing kit.
Also remember to check out how much sunlight your growing area gets, and that the rain drains well. If you treat your soil well and plan you crops according to your climate you will succeed with any plant you want.
The satisfaction when you harvest your own produce is well worth the time you put in 🙂
