Safety note

Keep off skin and out of eyes, and rinse with plenty of water if either happens. Do not apply before heavy rain is forecast, as the run-off reaches watercourses. Store dry, sealed and out of reach of children and animals; the prills look like something worth eating and are not.

About this fertilizer

A straight, balanced analysis for the times you want a predictable result. Ten percent each of nitrogen, phosphorus and potassium, prilled to a uniform size so it throws evenly out of a broadcast spreader and does not separate in the bag on the way to you.

Use it where the soil is broadly healthy and the planting is simply hungry: a hard-worked vegetable plot, a border carrying a lot of annuals, a new bed you have not had time to build up yet. It is fast, it is cheap per square foot, and it is honest about being a mineral feed rather than a soil improver.

Recommended uses

  • General feeding of vegetable beds through the growing season
  • Mixed ornamental borders that flower and fruit heavily
  • New beds where the soil has not yet been built up
  • Correcting a general lack of vigour across a whole plot
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. Measure the bed

    Work out the square footage first, because this is a mineral feed and over-application is the one way to damage plants with it. The rate is 1.5 lb per 100 square feet, which is about 3 level cups.

  2. Spread on damp soil, never dry

    Water the bed the day before if it has been dry. Broadcast the prills evenly across the surface, keeping them off leaves, crowns and stems. Do not concentrate the product in one spot around a plant.

  3. Water in immediately

    Give the bed a thorough soak straight after spreading so the prills dissolve and move down to the roots. Prills left sitting dry on the surface can scorch anything they touch.

  4. Wait six weeks before repeating

    Feed no more than every six weeks and stop by late summer. If growth is already strong and dark green, skip the feed rather than adding one you do not need.
