Water your Parlor Palm on a weekly basis, and make sure that the water is evenly dispersed across the soil. The last thing that you want is for water to pool up in your soil and damage your plant’s roots. Reduce the frequency of your watering sessions during the Winter, and remember that with this plant, it is better to under-water than to over-water.
To check the water levels of your plant’s soil, place a water meter in 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.
