You do not water everyday. You only water a plant when it needs it. When you water you want to saturate the soil down at the root zone. If you just water a couple of quarts everyday you aren't watering and if you are saturating the plant everytime you water you are killing it because of the lack of oxygen at the roots. You cannot give a plant too much water but you will kill a plant by water too often. So, having learned this, when you water give the plant gallons not quarts and don't water again until the plant is wilted in the morning hours. It is normal for a plant to wilt in the heat of the afternoon.
