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.
When growing seedless (triploid) watermelons, you must have a normal (diploid) watermelon growing alongside to provide the pollination. The pollinator can be any watermelon as long as it is blooming during the same time frame as the seedless variety.
