In 1964, the Gamman family were commercially growing citrus plants including feijoa and kiwifruit, alongside shelter belt trees for the New Zealand market and feijoa plants for export to Japan and Italy.
In 1975 they installed their first potting mix manufacturing plant and soil sterilisation unit.
The 1980's saw the introduction of the processing of Radiata bark for the commercial market. The crushing and vibrator screening of this bark enabled the stockpiling of the graded bark product you know today. Finer particles are used for potting mixes (after composting and nitrogen stabilising) and then the small, medium and large (up to 50mm) chips are suitable for the cultivation of commercially grown orchid plants through to the landscape sizes used in mulching and decoration.
In the mid 1980's, the Gamman family also obtained a mining licence over 180 hectares of peat lands in the Waikato region of the North Island and today continues to supply quality Sphagnum Peat to the horticultural industry of New Zealand.
