PLANTING and AFTERCARE GUIDE
Best Planting Time
Spring: Planting in spring allows Isolepsis cernua Fiber optic plant to establish strong roots as active growth begins.

Planting: Place the plant in the hole with the top of the root ball level with the surrounding soil, then backfill gently and firm lightly.

Watering Requirements
Growing Season: Keep the soil consistently moist during active growth. Isolepsis cernua Fiber optic plant thrives in damp conditions and should never be allowed to dry out.

Mid-Season: A light supplementary feed during the growing period can help maintain the vibrant appearance.
Pruning
Tidying: Remove any faded or damaged stems to keep the plant looking fresh and tidy.
Seasonal Care: Light trimming can help maintain the neat, fountain-like shape of the foliage.
Mulching
Spring: Apply organic mulch around plants growing in the ground to retain moisture and suppress weeds.
Ongoing Care: Maintaining consistent soil moisture is key to keeping the plant healthy and lush.
Supporting the Plant
