Basically, you insert your finger into the soil, and based if you feel the soil moist or dry, you determine if it needs any water, which is the most appropriate way to go about watering your leafy friend.

Soil Mix

As mentioned earlier, the Japanese Maple prefers to have soil with good drainage, and moist properties at all times, reason why you need to make the soil mix out of clay, loam, chalk, and sand.
