Product Description


Trench Fertiliser 6-11-18

Elixir Gardens Trench Fertiliser is a special formulation suited 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. It is recommended to add this product to flower/seed beds as soon as possible after the old crop is removed.

Recommended Use:

  • It is recommended to use this 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.
  • If Lime or manures are needed to correct pH or soil structure it is safe to do so at the same time as usage of this fertiliser.

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