Fast repot

Repot in completely dry, fresh potting mix. Do not water for 3-5 days.

Stress reduction

Place in bright indirect light, away from direct sun. Reduce watering frequency significantly.

Organic Treatment

Remove and assess

Carefully remove the plant from its pot and gently wash away all soil from the roots. Assess the extent of root damage.

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

Brew strong chamomile tea and let it cool. Soak the remaining roots for 15-20 minutes.

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.

Repot carefully

Plant in the new soil, ensuring the root crown is at the proper level.

Initial watering

Water lightly with diluted neem oil solution (1 tsp per liter of water).
