Convert any numeric values to characters using the num2str function. Use disp to display the string. Use sprintf to create a string, and then display it with disp. Use fprintf to directly display the string without creating a variable.
Watermelons need a long growing season (at least 80 days) and warm ground for seeds to germinate and grow. Soil should be 70 degrees F or warmer at planting time. Sow seeds 1 inch deep and keep well watered until germination.
Generally, watermelons have two types of growth habits: bush and vine. The bush varieties can grow 2 feet apart in rows 4 to 6 feet apart. Vining varieties may require 5 to 6 feet between each plant and 6 to 8 feet between each row.
