This is the easiest and cheapest method of watering your raised bed garden crops. You can pour water with a small bowl over your plants and use your hand to break the force of water. You can also use a watering can with a sprinkle nozzle.
You can always use a garden hose instead of a watering container. If your plants are young and tender, do not point the hose directly at them.
Sprinklers are easy and fun to use in raised bed gardens. Sprinklers distribute a uniform amount of water to crops around them. Remember to position your sprinklers so that every plant can receive an even amount of water.
