Safety note

Concentrate is an irritant before dilution. Wear gloves, keep it off skin and out of eyes, and rinse thoroughly with water if contact happens. Never decant it into a drinks bottle. Store it upright, sealed, above freezing and out of reach of children.

About this fertilizer

A clean mineral concentrate for the weeks when a plant needs feeding now rather than in a month. It goes into solution completely, so it will not block a rose head or a sprayer nozzle, and the nitrogen is available to the plant as soon as it reaches the roots.

Nitrogen-led at 6-2-4 with a full trace element package, it suits leafy growth, container plants that have exhausted their compost, and anything looking pale halfway through the season. It is a feed rather than a soil improver, so it works best on top of ground that already has organic matter in it.

Recommended uses

  • Weekly feeding of containers, baskets and window boxes
  • Greening up leafy crops such as lettuce, chard and brassicas
  • Pale or slow houseplants during the growing months
  • A quick correction while a slow-release feed gets going
How to apply it

Application instructions

Follow these in order. The rates below are the ones we test to, and going over them will not make anything grow faster.

  1. Dilute for regular feeding

    Mix 1 fluid ounce, about 2 tablespoons, into 1 gallon of water. Stir it and use it the same day; made-up feed does not keep well once it has been standing.

  2. Water onto damp compost

    Water the plant with plain water first if it is dry at the root, then apply the diluted feed until it runs from the bottom of the pot. Feeding a bone-dry root ball is the usual cause of scorched leaf edges.

  3. Feed on a schedule

    Once a week through spring and summer while plants are in active growth. Halve the rate for seedlings and anything recently potted on, and stop feeding entirely once growth slows in autumn.

  4. Foliar feed if you prefer

    For a faster response, halve the concentrate to half an ounce per gallon and spray the leaves until just wet. Do this early morning or evening, never in direct midday sun.
