Soil Types and Watering Information

Loam Soil:

Very porous and retains moisture well. This is the optimal soil type and can be watered normally.

Sandy Soil:

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

Clay Soil:

Holds more water, but is slow to absorb and release. Do not water faster than the soil can absorb it.

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).
