The complexity of bee foraging behaviour and the wide range of potential nectar source plants near an apiary site, can make initial identification of a honey type challenging. For example, bees may forage from other plant species near an apiary site even when Manuka is the most abundant flowering plant at the site.

In any wild population of Manuka plants, there is wide variability between phenotypes. Up to 90% of the plants may have less than desirable characteristics. The typical flowering timeframe will occur over a 6 week period. Some plants will produce a lot of flowers while others minimal. The flowers may produce varying amounts of nectar, […]

Megan Grainger, PhD, Honey Team Leader and Technologist, Analytica Laboratories. Manuka honey, derived from the Leptospermum scoparium (manuka) tree, is unique due to its non-peroxide antibacterial activity. This arises from the presence of methylglyoxal (MG) in the honey. This activity can be expressed as Non-Peroxide Activity (NPA). A conversion equation based on published data (1) […]

Manuka on target to be the most profitable land use option for marginal land Manuka production is a sound economic option for New Zealand farmers seeking better economic returns from marginal farmland. Marginal land tends to have a shallow layer of topsoil and therefore tends to grow poor grass species and not much grass at […]

The significance of DHA, MGO, HMF and Leptosperin in Manuka Methylglyoxyl (MGO) is found predominantly in Manuka honey and is the main chemical responsible for the unique non-peroxide antibacterial activity of the honey.

Demand for Manuka plants for Manuka plantations is increasing rapidly. Plant Selection Manuka plants produced in the nursery for Year 2015 deliveries have already sold out and orders have started coming in for Year 2016 plantings. It is advisable to prepare early for a new Manuka plantation, to ensure that you have the best chance […]
