In the first week or two, your new elephant ears should be watered every day. Once this timeframe has passed, you’ll have to touch the soil to determine if it needs water. Generally, you’ll want to give your elephant ears between 2 and 3 inches of water per week, however, it may be a little bit more than that if the soil is dry. Remember, watering your elephant ears in the afternoon will make the soil dry up faster, so you’ll have to water it more. Due to this heavy need for water Elephant ears will show signs of dehydration by drooping leaves. The unfortunate side effect of this is that, unless you have well-draining soil, you may end up overwatering the plant. Water first thing in the morning when temperatures, both inside and outside, are still cool.
