Remove and assess

Prune affected roots

Using sterile scissors, cut away all soft, mushy, brown, or black roots. Cut back to healthy white tissue.

Apply cinnamon

Dust all cut surfaces generously with cinnamon powder to prevent fungal regrowth.

Prepare chamomile soak

Air dry roots

Let the roots air dry for 2-4 hours in a shaded area with good air circulation.

Prepare new container

Clean the pot with diluted vinegar, rinse well, and fill with fresh sterile potting mix.

🌱 How to Care for Lady Fern to Prevent Root Rot?

💧 How to Water

Water whenever the top inch of soil starts to feel dry to the touch — never let the rootball dry out completely, but avoid soggy, waterlogged soil. Consistent moisture is the single most important factor for healthy fronds.

☀️ Lighting

Best in dappled or full shade; tolerates a few hours of gentle morning sun if the soil stays moist, but protect from hot afternoon direct sun, which scorches the delicate fronds.

🪴 Ideal Soil

Use a rich, well-draining, humus-heavy soil (leaf mold, compost, peat-free potting mix) with a slightly acidic pH between 4.5 and 6.5. Mulch with leaf litter to retain moisture and mimic its natural forest-floor habitat.
