Water your Ivy on a biweekly basis, and make sure that the water is evenly distributed throughout the soil. Remember to keep the plant’s soil moist, but don’t allow it to become too saturated with water and begin to pool. This will be extremely harmful, and potentially lethal, for your plant.
To check the water levels of your plant’s soil, place a water meter several inches 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.
