Extremely porous and drains quickly. Water slowly to saturate soil root zones.

General Soil Moisture Information & Tips
- If you have sandy or very heavy clay soils and would like to improve its water retention, add compost or organic matter to your soil.
- Adding sand to clay soils, or clay to sandy soils will create a cement-like soil, making water retention worse.
- One inch of water per week is adequate for most plants. You may use a rain gauge to assist (not included; sold separately).
