The kentia palm prefers to be well-hydrated, but never soggy. Water your kentia palm weekly in the spring and summer, allowing the soil to dry out between waterings. During the fall and winter months, you can likely slow your watering cadence down a bit, but look to your plant as an indication.
Once Kentia palm plants have established, they require very little care. Feed your container grown plants with a controlled release fertilizer with an NPK ratio of about 3-1-2. Excessive fertilization may cause the tips of lower leaves to turn brown and die.
Kentia palms prefer indirect sunlight. Do not expose the plant to direct sun unless it is acclimated as a seedling to direct sun—otherwise, it will likely scorch.
Kentia palms are considered to be moderately tolerant of salt spray and can tolerate cold down to 25°F, making them suitable for growing in USDA plant hardiness zones 9b (25–30°F) to 11 (above 40°F).
Avoid repotting the Kentia Palm unless absolutely necessary (risk of root rot, for example). Kentia Palms have delicate roots and do not like to be repotted. Pot sizing - if you want your plant to grow wider, find a nursery pot that's 2” in diameter larger than the current pot.
