A watering system includes a bottle unit or a water level control unit which has a float member to control the water level of the tank in a planting hole. The float member controls the operation of the water inlet valve and the water level in the bottle unit so as to control the amount of water that the planting hole provides to the soil outside the planting hole without using electricity. The plants are properly watered automatically all day long. The water permeates into the soil outside the planting hole to water the plants that are planted in a larger area. The watering system is suitable for watering the plants in a large area or in pots. 1.
