Because individual fruits are pollinated at different times, multiple harvests are usually necessary. After harvest, growers should check watermelons for size, maturity, and pest damage to ensure marketing of a high-quality product. Cooling the watermelons after harvest to 45-50°F will remove field heat and improve shelf life and taste. Watermelons will retain good quality for approximately 21-28 days if stored at 85-90 percent humidity and 47-55°F.


What is the best soil for watermelon?

Watermelons grow best on soils that hold water well and have good air and water infiltration rates. Soil should have a pH of 5.8-6.6.

The best average temperature range for watermelon production during the growing season is between 65°F and 95°F. Temperatures above 95°F or below 50°F will slow the growth and maturation of the crop. Watermelons require a constant supply of moisture during the growing season. However, excess water at any time during crop growth, especially as fruit reaches maturity, can cause the fruit to crack, which will reduce crop yields and fruit quality.


How to control watermelon weeds?

Weed control can be achieved with herbicides, plastic mulch, and a good crop-rotation system.

Cucumberbeetle, aphids, seed corn maggot, leafminers, and rindworms (cucumber beetle larvae) can all cause crop losses. Monitoring insect populations with traps and scouting will help you determine when to apply pesticides and how often to spray. Several watermelon diseases can cause crop losses, including bacterial fruit blotch, fusarium wilt, powdery mildew, downy mildew, and gummy stem blight. Viruses such as cucumber mosaic (CMV), squash mosaic (SqMV), and watermelon mosaic (WMV-1, 2) are also a problem. These diseases can be controlled by using disease-resistant varieties and by having a good crop-rotation system and soils with good air and water infiltration rates.
