When tending to the water needs of the Japanese Laurel, you want to make sure that its soil is always slightly moist. However, do not allow the soil to get soggy, as this could result in complications such as root rot. Water on a weekly basis, and allow the first couple inches of soil to dry before watering once more. If your soil is drying quicker or slower than anticipated, adjust your watering schedule to account for it.
To check the water levels of your plant’s soil, place a water meter into the soil, where it will give you an accurate indication. If you do not own a water meter, stick one finger knuckle-deep into the soil. At this depth, you will be able to accurately account for the soil’s level of moistness.
