Life cycleKimberley Queen fern does not have any significant flowering or harvest periods as it is grown for its foliage. Here are the different stages of life of Nephrolepis obliterata:
Propagation: Nephrolepis obliterata can be propagated by spores or division of the parent plant. Spores can be sown in the spring or summer, while division can be done at any time of the year.
Seedling stage: Nephrolepis obliterata usually takes about 2-4 weeks to germinate from spores. Once the seedling emerges, it will take about 6-8 weeks to grow to a size that can be potted up.
Vegetative growth: After the seedling stage, the plant will continue to grow vegetatively. The growth rate will depend on the plant's growing conditions such as light, temperature, and soil quality.
Maturity: Nephrolepis obliterata can reach maturity after 2-3 years of growth, at which point it will have developed a full, lush foliage.
Reproduction: Nephrolepis obliterata can reproduce through spores, which can be collected from mature fronds, or through division of the parent plant.
PropogationPropogation time
Spring - early summer
Kimberley Queen fern can be propagated by spores or by dividing the plant. Spores are produced on the underside of the leaves and can be collected and sown in a container with moist soil. The container should be kept in a warm and humid place until the spores germinate and develop into small ferns.
Division is typically done when the plant outgrows its current pot or becomes root-bound. To propagate through division, carefully remove the plant from its container and gently separate the root mass into smaller sections, each with its own crown and roots. Replant the sections in containers with fresh potting soil and keep them moist until they establish new roots.
The best time to propagate Nephrolepis obliterata is in spring or early summer when the plant is actively growing.
