Application Rates:

Liquid Feed Application:
Used in the same way as other water-soluble fertilisers. Feed is usually applied via a normal watering can. Simply add the appropriate amount of Feed to the can, add water and apply liberally to the plant root area. A very approximate guide is 5 litres per square metre. Feed is best applied as a liquid feed whilst the plant is actively growing. Ideally alongside watering. The standard rate is 1g / litre of water. However this can vary anywhere between 0.5g / litre – 2g / litre. Use the lower rates for sensitive plants, such as pot plants under glass. The higher rates should be used on rapidly growing plants in outdoor soils. DO NOT exceed 2g / litre.
Foliar Spray:
Plants are designed to take up nutrients through their roots, but most nutrients can be absorbed through the leaves. Foliar feeding can give crops a valuable boost. Particularly if the root system is not functioning well due to drought, disease or pest attack and other stress factors. Pay attention to the following:
  • Use a sprayer nozzle that produces a fine mist.
  • Only apply sufficient spray solution to to coat the leaves and stems with a film of moisture with little or no “run-off”.
  • Carry out spraying on a calm day, but not during strong sunshine or high temperatures. The best time is late afternoon or evening.
  • Postpone spraying if rain is imminent. If rain falls within 4 hours of spraying, re-spray the crops 3 or 4 days later.
  • For application via hose-end diluters, please refer to the device manufacturer’s directions for use.
  • If you are in an area with acute hard water, Soluble NPK fertilisers can dry on the leaves and leave unsightly residues.
Prepare a 0.05 – 0.1% (0.5 – 1.0 g / litre) solution and apply to coat the leaves and stems with a thin film of moisture, with little or no “run-off”. DO NOT exceed a 1g per litre concentration.
