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.
Watermelons prefer sandy loam soil over others. Growing watermelons also requires space, as the plants are vines and take up a lot of room. Another of the tips for growing watermelon is that the transplanted watermelon seedlings should be planted by themselves 2 to 3 feet apart. You should definitely include 7 to 10 between rows.
