Coir-Based Potting <ix

Made from shredded coconut husks, coir is sold either loose or in blocks; the latter need to be soaked for about 20 minutes before use. Since coir has no nutrients, it is generally mixed with multipurpose potting mix (one-third coir to two-thirds additional potting mix). Use it for annual displays in pots and containers where a light weight potting mix is needed, such as windowboxes and wall pots, or on balconies. It dries out quickly and plants will need to be watered frequently.

- Inexpensive.
- Lightweight.

- Not entirely "green": peat-free, but it uses up thousands of air miles.
- Not for permanent displays.
- Plant performance can be variable.
