Aroid Soil Mix

Knowing when to repot a variegated Monstera is more important than repotting on a fixed schedule. A plant that is growing well in an airy mix does not benefit from having its roots disturbed simply because a year has passed. Quick answer: repot when the roots have clearly outgrown the container, the substrate has broken down and drainage has slowed, the pot is mostly roots and dries extremely fast, or you need access to damaged roots. Move up only modestly in pot size and use a chunky, well-aerated mix. ...

A good aroid soil mix should hold enough moisture for the roots to use while still draining freely and leaving plenty of air spaces. For many Monsteras and Philodendrons, a practical starting recipe is 3 parts orchid bark, 2 parts coco coir or peat moss, 2 parts perlite or pumice, 1 part horticultural charcoal, and 1 part worm castings.
