Safety note

Keep off skin and out of eyes and rinse well with water if contact happens. Do not apply immediately before heavy rain, as run-off carries phosphorus into watercourses where it does real damage. Store sealed, dry and out of reach of children and animals.

About this fertilizer

The classic fruiting analysis. Half the nitrogen of a balanced feed, double the phosphorus and potassium, which is the ratio you want once a plant has enough leaf and needs to put its energy into flowers and fruit instead.

The usual reason for a tomato plant six feet tall carrying four fruit is too much nitrogen too late. Start the season on something balanced, then switch to this once the first flowers open and let the plant get on with cropping.

Recommended uses

  • Tomatoes, peppers, aubergines and cucumbers once flowering starts
  • Squash, pumpkins and melons through fruit set
  • Roses and repeat-flowering shrubs
  • Any plant making plenty of leaf but little flower
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. Start at first flower

    Wait until flowers are actually opening before switching to this. Applied too early it slows the leafy growth the plant still needs to build a crop on.

  2. Apply at 1.5 lb per 100 sq ft

    Scatter evenly across damp soil around the plants, keeping the granules off stems and leaves, then water in thoroughly so nothing sits dry against the plant.

  3. Repeat every four to six weeks

    Continue while the plant is still setting and swelling fruit. Stop once picking has finished, or about six weeks before your first expected frost.
