How to grow and maintain Kimberly Queen Fern (Nephrolepis obliterata):
It thrives best in bright, but indirect sunlight. Avoid direct sunlight and deep shade.
It grows well in humus rich soil. Use a peat-based potting mix, 2 parts peat and 1 part perlite is one mixture that will be fine. A peat based mixture with organic material is also good.
Water your plant regularly during the growing season and always keep the soil evenly moist but never allow your plant to sit in water. You can allow the topsoil to become slightly dry between each watering. During the winter months, reduce watering.
It thrives well in room temperatures between 65 degrees Fahrenheit – 75 degrees Fahrenheit / 18 degrees Celsius – 24 degrees Celsius are ideal, and no lower than 55 degrees Fahrenheit (13 degrees Celsius).
During spring and summer, fertilize weekly or biweekly with balanced liquid fertilizer diluted by half. Deformed leaves with brown or yellow spots or edges are a sign of too much fertilizer.
Re-pot the Kimberly Queen Fern once every 2 years in the spring, moving the plant into a pot only one size larger.
Pick-off yellowed leaves and older fronds as desired. You may also trim off the hair-like projecting stems. Keep to desired height and shape with light pruning or clipping at any time.
It can be propagated by division of the rooted runners. Divide older plants every 3 – 5 years. Use a sharp knife and slice the rootball in half or quarters. Replant each piece. Trim any damaged fronds.
