Yates Nutricote Standard Grey 70 Day – 16 : 4.4 : 8.3

Yates Nutricote Standard Grey is a controlled release fertiliser designed specifically for use on foliage plants. It contains the highest quality NPK and is suitable for exotics and most natives.The advanced prill coating provides superior control of nutrient release over 70 days at 25°C.

Yates Nutricote Standard Grey matches nutrient release with plant growth and growing conditions. During warmer periods nutrient release increases to support accelerated plant growth. In winter when temperatures fall, and the slower plant growth results in a decreased nutrient demand, the prill release rate also slows down. This facilitates a more cost-effective nutritional programme and also minimises nutrient loss through leaching.

Suitable for: Foliage plants

Yates Nutricote Standard Grey consists of small prills which contain nitrogen, phosphorus and potassium. Advanced coating technology is applied to each prill that then controls the rate at which nutrients are released to match the physiological growth stages of the plant. It enables growers to produce the highest quality plants with minimised nutrient stress, dumping or root and foliage burn.

Once prills have been applied to the potting mix or soil, moisture starts to penetrate into the polymer coating. This causes the nutrients inside to dissolve and creates osmotic pressure within each prill. It’s this pressure that drives the gradual and controlled release of the nutrients. The rate of release is even and determined by soil temperature. Increased soil temperatures will result in increased nutrient release as plant growth and nutrient needs increase.

Top Dressing

  • Evenly apply to the base of the plant, keeping fertiliser away from the main trunk or stem.
  • Water in well after application with a rose type spray to minimize water blast of prills from pot.


Mix well into the soil profile ensuring even application.


  • Release period is governed by soil temperature as shown below.
  • Nutricote should provide the entire requirements of nitrogen, potassium, and maintenance levels of phosphorus for the release period.
  • Use high rates for fast-draining soils or mixes of low fertility and for species that are fast-growing and watered frequently.
  • Use medium rates when:
    • Using on sensitive crops
    • Soil temperatures are very high
    • Liquid feeding two to three times per week
