Potting Mix Basics: The Secret Behind Healthy Roots

Soil Is Not Just “Mud”

Garden soil from outside often becomes compact and airless in pots. Indoor and balcony plants need a mix that holds some moisture while still letting roots breathe.

What a Good Mix Does

• Holds water without becoming swampy
• Allows oxygen to reach roots
• Drains excess water quickly
• Supports steady, healthy growth

Simple All-Purpose Indoor Mix

• 40% quality potting soil
• 30% cocopeat
• 20% perlite or river sand
• 10% compost or vermicompost

For Succulents and Snake Plants

• More grit, less water retention
• Add extra perlite, sand, or brick dust

For Ferns and Peace Lilies

• Slightly richer and more moisture-retentive
• A little more cocopeat and compost

Repotting Signs

• Water sits on top and drains slowly
• Roots circling out of drainage holes
• Plant dries out too fast or stays wet too long
• Growth has stalled for months

Repotting Tips

• Choose a pot only 2–5 cm wider than the current one
• Always keep drainage holes open
• Water lightly after repotting, then resume normal care
• Don’t bury the stem deeper than before

If leaves yellow for “no reason,” check the mix first. Roots live there every hour of the day.
