aroid soil mix on Philodendron
Quick answer
If your Philodendron has aroid soil mix, the most likely cause is: Aroid epiphytes evolved growing on tree bark with rapid drainage, high air circulation at roots, and organic debris. Standard potting soil is too dense, causing water retention and root suffocation.
Start here:
- 1. Mix 40% high-quality potting soil (peat or coco coir base)
- 2. Add 30% perlite or pumice for aeration and drainage
