Lawn & Garden FAQ

How much SandyCal do I need?

We always suggest a soil test to help determine your soil’s needs. However, as a general rule of thumb, approximately 500-750 lbs. per acre is advised. For smaller areas, please see our guide.

How do I set my spreader?

Mark off an area that is 1,000 sqft. or 20’ x 50’.

  1. Using the instructions on the bag, determine the amount of product you need per 1,000 sq. ft.

  2. Add the determined quantity to your spreader and set your spreader to medium. Walk at your normal pace over the marked area.

  3. If you have material left in your spreader at the end, your setting is too low. If you have run out of material part way through, your setting is too high.

  4. Adjust as needed. All spreaders will have different calibrations, and this method will provide the most accurate calibration for your spreader.

How do I apply SandyCal?

There are several ways to apply SandyCal:

  1. Apply using a garden spreader. Follow the instructions below for how to set your spreader.

  2. If using in a very small area or potted plant, hand spread over the soil, then water as normal.

  3. If applying before planting, spread over the soil and till in. Plant as normal.

How do I apply OceanCal?

There are several ways to apply OceanCal:

  1. Sprinkle directly on desired area.

  2. Mix with water. Mix 2-4 lbs. of OceanCal in 1 gallon of water and use promptly. (OceanCal will settle if not used immediately.)

  3. Incorporate into irrigation system. Use a tote mixer in your irrigation system to keep it agitated and prevent settling.
