General Application Principles

The basic principle of Bradfield Organics® fertilizers is to build quality nutrient and biologically rich soils. The general recommendations below are guidelines that will give you a 3-star performance the first year and move gradually over 3 to 4 years to a 5-star level of performance. Increasing your application dose (a double dose is always acceptable) will only move you quicker to the higher level of performance. As in nature, there is no bad time to start building your soils. Applying when it's hot, cold, wet or dry, makes no difference in the long run. We generally recommend our Bradfield Organics® fertilizers be applied at 40# per 1000 sq ft (19.6 kg per 100 sq meters), on an annual basis, for a minimum dose. 120# per 1000 sq ft (59 kg per 100 sq meters) annually would be a maximum dose for any growing situation. These amounts can be applied over 3 to 4 applications (generally at 90 day intervals) per season as your schedule permits. If you chose the maximum dose and maintain that level for three years, our expectation is that you should see a high quality and easily sustainable lawn or garden with a very low dose (probably 20# to 30#) annually for long term maintenance.

The above applies to any combination of our products you choose to use.
