Controlled Release

Nutricote Blends Tree & Shrub Total 180 Day - 16.8 : 3.9 : 8.1

Staged nutrient release fertiliser


  • Superior control of nutrient release over 180 days
  • Contains the highest quality NPK and TE components
  • Earlier response for cooler climates
  • Staged nutrient release consistent with plant needs
  • Suitable for natives and exotics
  • Robust coating for increased safety

By matching nutrient release longevity with plant growth and growing conditions, the loss of nutrients through leaching is minimised, this facilitates a more cost effective nutritional programme and reduced concentrations of nutrients are introduced to the environment; Nutrient release is matched to plant needs, ie. in winter when temperatures fall, plant growth slows and lower levels of nutrients are required, while the rate of nutrient release also slows in response to lower temperatures; Technical support and advice is available for all Nutricote products; Nutricote is manufactured to the highest quality standards.

How It Works

Nutricote controlled release fertiliser (CRF) consists of granules (prills) of fertiliser that have been polymer coated. Each prill contains NPK and depending on the formulation, may contain trace elements as well. After prills are applied to potting mix or soil, water vapour starts to penetrate into the coating. The nutrients inside are dissolved and an osmotic pressure is formed, followed by gradual and controlled release of the nutrients. Nutrients are continually released during the stated longevity. The rate of release is determined by soil temperature. As soil temperature increases, the rate at which nutrients are released also increases.

Directions for use

Nutricote is suitable for application to both container grown and field grown plants. Nutricote can be applied in 3 ways -

  • Incorporation through potting mix or soil, before planting;
  • Dibble application, whereby fertiliser is placed beneath or to the side of the rootball when potting up;
  • Topdressing, whereby fertiliser is applied around the plant on the surface of the potting mix or soil, at any time of the life of the crop.

Application rates can vary from 3g/l to 5g/l of growing media. The application rate is determined by the longevity of the product used, container and plant size, planting time, the growing season of the crop and even the application method (ie. dibble application rates are generally 15 – 20% lower than incorporation or topdress rates). Always refer to Nutricote label recommendations before use.


Always read label recommendations before use. Do not use these formulations on phosphorus sensitive Australian native plant species. Do not dibble apply products with longevity ratings of 70 days or less, as the high concentration of nutrients released into a limited volume of potting mix can damage plants in high or fluctuating temperatures.

Additional Information

The release rate of Nutricote products are based on an average day/night soil temperature of 25 degrees Celsius, with the exception of 8-9 mth Special Blend. The longevity of this product is based on 21 degrees C. Release response to temperature is entirely predictable.
