The ideal soil temperature for watermelon seed germination ranges from 75°F to 85°F (24°C to 29°C). It is advisable to use a soil thermometer to monitor the temperature accurately and ensure optimal conditions for your watermelon plants.
Recommended Planting Time
In Arizona, it is generally recommended to plant watermelon seeds in late spring or early summer, once the soil has warmed up sufficiently. The average last frost date in Arizona varies depending on the location, ranging from mid-March in the southern parts of the state to late April in the northern regions. It is crucial to choose a suitable planting date based on your specific location.
Factors to Consider
