How to care for Korean Tasselfern

Difficulty

With its straightforward care requirements, Korean Tasselfern is a hassle-free plant that anyone can enjoy.

Soil

Korean Tasselfern is very sensitive to dry soil. To ensure your Japanese Lace Fern is thriving and blooming, choose a potting soil that retains moisture. A good soil should still allow for adequate drainage and contain lots of organic matter. Coco coir or sphagnum moss are great soil additives that will help to retain moisture and provide your Korean Tasselfern with the nutrients it needs for healthy growth. Make sure to mix these soil additives into the potting soil before planting and water the soil thoroughly. By providing your Korean Tasselfern with a well-draining, moisture-retaining soil, you can help to maximize its growth and keep it blooming.

Lighting

Korean Tasselfern requires abundant, bright, and direct light to thrive. The best placement for this plant is within one foot of a window to ensure it receives enough light. If you live in an area with more extreme weather, such as hot summers or cold winters, you may need to adjust the placement of the plant accordingly. During hot summer months, it is important to place the plant away from full sun, as this can cause the leaves to yellow or burn. During cold winter months, it is best to move the plant closer to the window to take advantage of the extra light that can help it survive. By keeping an eye on the current weather in your area, you can make sure your Japanese Lace Fern is always in the right place to thrive.

Toxicity

There is no verified data on the toxicity of this plant in the records of Ploi. If any person, including yourself, a family member, or a pet, consume plant material with an uncertain toxicity level, it is advisable to seek the advice of a healthcare expert.

Fertilizer

Repotting the Korean Tasselfern should be done either when it has doubled in size or on a yearly basis, whichever occurs sooner. Fresh potting soil with all the required nutrients, refreshed annually, will provide the plant with all the necessary sustenance, making the use of fertilizer unnecessary. Keep in mind that plants receive their energy from the sun, not fertilizer.

Growth-pattern

New growth will sprout from the top of the Korean Tasselfern as it grows vertically.
