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.
Varieties: Green Flesh, Honeydew. Honeydew melons are somewhat unique for their smooth, cream-colored outer skin and lack of 'netting' ridges on the rind. They take a bit longer than most other melon varieties, sometimes as long as 120 days after germination to produce the smaller (3-6 pound) melons. Honeydew is popular in Europe, Asia and other regions thanks to the sweet, green flesh. Seeds or Seedlings. 3 to 5 days, 60F to 95F.
