how long before watermelon is ready to pick
When you knock on it with your knuckles it should give off a dull, hollow sound. Not all make the hollow sound, so if it does not sound that way, it does not necessarily mean that the watermelon is not ready to harvest. Watermelon should be ready about 80 days after it is planted. At about the 75-day mark, start keeping your eye on it to see if it is ripe.
