build healthy soil 

The Right Start

Foundations are essential for any planting job

  • California's native soil has less than 5% organic matter - meaning it is primarily mineral, sand & clay. It is lacking in nutrients and is not an ideal home for most garden plants.
  • All our soil offerings are loaded with mycorrhizae which is a beneficial fungus that attached itself to the roots of plants and acts as an extender to reach more nutrients and water. Recreating this symbiotic relationship in your garden allows your plants to thrive to their fullest.
  • Soil texture is intrinsic to plant health - it means water can flow through and be absorbed at the correct rate for roots to take up water & nutrients, yet not drown. Adding organic matter is the solution for creating workable, healthy soil.

starter fertilizer

Good Foundations

  • Using fertilizer right at the root level is essential to get the most out of your plants. Transplanting can be stressful - the simplest way to combat root shock is to incorporate all the nutritious material when planting.
  • Some essential nutrients, such as phosphorus, are extremely slow-moving through the soil. In order for the plant to benefit from being fed right away - the fertilizer must be added into the planting hole or directly onto the roots. This can only be done one time, so don't miss the opportunity when you are transplanting.
