A Simple Potting Mix for Indian Balconies and Terraces

Most potted plants that die early don't die from lack of care. They die because the soil is wrong. Garden soil straight from the ground packs down hard in a pot, holds too much water, and starves the roots of air. A good potting mix fixes this.

The basic recipe

Mix these three parts by volume, and adjust based on what you have:

• Garden soil or topsoil: the body of the mix, which holds nutrients and gives the roots something to grip.
• Compost: feeds the plant slowly and improves how the soil holds water. Well-rotted home compost or bought vermicompost both work.
• Coco peat or fine sand: keeps the mix loose so water drains and roots get air.

A common starting point is equal parts of soil, compost, and coco peat, with a little sand added if the mix still feels heavy.

Test the drainage

Fill a pot with the mix, water it well, and watch how fast the water runs out of the bottom. Water should pass through within a minute or so. If it pools on top or drains very slowly, add more coco peat or sand. If it runs straight through and the soil dries within hours, add a bit more compost.

Mix it well

Use a khurpi or your hands to break up lumps and blend the ingredients evenly. Dry coco peat can be hard to wet, so soak it in water first, squeeze out the extra, and then mix it in. A khurpi is handy for this because its narrow blade reaches into the corners of a large bucket.

Avoid the common mistakes

• Using only garden soil: it compacts in pots and rarely drains well enough.
• Adding too much sand: pure sand dries out too fast and holds little food for plants.
• Reusing old soil without refreshing it: after one season, top up with fresh compost and mix in some new coco peat before replanting.

Refresh it each season

Potted soil loses structure and nutrients over time. At the start of each season, scrape off the top few centimetres, mix in fresh compost, and repot anything that has outgrown its container. Doing this once or twice a year keeps your pots healthy without much extra work.
