Frequently asked questions
Before you send an enquiry
Is WinHarvest a fertiliser importer and wholesaler?
Yes. WinHarvest is an Australian-owned importer and wholesaler of specialty fertilisers, based in Deer Park, Melbourne, serving distributors, growers and formulators across Australia. Specialty blends and tailored formulations are sourced or arranged through our supplier network, not manufactured or blended in-house.
Which specialty fertilisers can I enquire about?
Compare the listed water-soluble fertilisers, micronutrients, chelated products and liquid fertiliser inputs, then review the exact product grade and intended application. Not every product has the same specifications or packaging.
What is the minimum order for wholesale fertiliser?
Minimum order quantities depend on the product, grade, packaging and supply arrangement. Send your required quantity and delivery postcode; Sales will confirm the applicable minimum order and quote. There is no single minimum tonnage for the entire catalogue.
Does wholesale supply always mean bulk packaging?
No. Wholesale describes the commercial supply arrangement; packaging is product-specific. Review the listed pack size and ask Sales to confirm the options for your order, including whether larger packs are available.
Can I request an SDS or COA?
Yes. Include the exact product name and grade. SDS and batch-specific COA documents are supplied through the controlled sales process.
