Hair loss is another sign that thyroid hormones may be out of balance. Both hypothyroidism and hyperthyroidism can cause hair to fall out. In most cases, the hair will grow back once the thyroid disorder is treated.
However, watermelons need a long, warm growing season to flourish. Knowing when to plant watermelon will help you harvest a bounty of large ripe melons. Watermelons can grow in USDA Hardiness Zones 3 through 11 and need 70 to 90 days to reach maturity, depending on the variety. Soil temperatures must be at 60- to 65-degrees Fahrenheit at the 4-inch depth, or watermelon seeds will not germinate. Average air temperatures must be between 70 and 85 degrees Fahrenheit.
At a minimum, seeds should not be planted until after the last frost. The warmer the weather is, the faster the seeds will germinate and the plant will grow. According to Essential Garden Guide.com, watermelon seeds take about 12 days to germinate when the average temperature is 68 degrees Fahrenheit. That time is reduced to four days when the temperature averages 86 degrees Fahrenheit.
