Product Description


Trench Fertiliser | N.P.K 6-11-18

Trench Fertiliser is specially formulated for growing exhibition crops and decorative plants such as Leeks, Onions, Sweet Peas, Delphiniums and Rose Beds. Early preparation of the soil is essential for these plants to grow properly for exhibition use. We recommend adding this product to flower/seed beds as soon as possible, after the old crop is removed.

Recommended Use:

  • Recommended use is over the winter to prepare the area to grow your exhibition flowers and vegetables.
  • Keep in mind that trenches are traditionally double-dug, and will require a uniform application of the fertiliser throughout both spits.
  • Safe to use in conjunction with limes or manures for correcting soil pH and structure.

The recommended application rate is to use 110g – 170g/sqm.
