Sahi kahan aapne. Mene jab calathiya ka variety buy kiya, to woh kewal coco peat mein laga hua tha. Mene uske root ball ko bina chede hi river sand and patto ki khad mein daal diya bade pot mein. Woh 3 months se theek chal raha hai.
Calathea soil mix. Cocopeat Sand or soi Perlite Neem khali Vermi compost Charcoal Coconut la shilkha. Cut in small pieces. Dead plant v survive kar jayega. I have done with all my calathea plants❤
