Why SureGrow?

If your soil is highly compacted, having trouble holding water, or low in organic matter and nutrition, compost is an excellent addition. Compost improves the soil's physical and chemical characteristics allowing for healthy growth of virtually any kind of plant by:

  • Replenishing nutrients in soil
  • Promoting healthier root growth
  • Improving soil structure
  • Increasing water and nutrient holding capacity

SureGrow is produced under industry standards to meet the requirements of category “A” compost. Refer to the Canadian Council of Ministers of the Environment for details.

Directions for use

The following application amounts and frequency are guidelines. Use your judgement and monitor your vegetation to determine the best rates for your environment.

Potted Plants
Do not plant in pure compost. To root properly, plants must have the texture provided by soil. Mix one part compost with three parts potting soil.
To establish a new garden or prepare a garden for planting, till the soil to a depth of 8-10 inches. Apply a four-inch layer of compost and mix thoroughly into the soil.
On established lawns, apply compost once per year in layers one-quarter inch to one-half inch thick. Water well. To prepare soil for a new lawn, till four inches of compost into eight inches of soil.
 Trees and Shrubs
Lay one inch of compost around trees one foot away from the trunk out past the drip line. Use a two-inch layer for shrubs. Apply once per year.

Do not plant directly into SureGrow or any other compost. Compost should be blended thoroughly with soil and/or other non-compost amendments (such as peat moss).
