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.
Weak, neglected vines produce spindly, poor quality fruits. Fertilize with a ratio of one part nitrogen to four parts phosphorus at planting. Make your own by mixing fertilizers together or purchase a high phosphorus product. Add nitrogen 30 and 60 days after planting to keep the vines growing. Large vines result from lots of water and fertilizer, so allow plenty of room. Minimum spacing essential for all but bush-type melons is two by four feet, but most need even more room. Close planting results in little or no fruit production.
