We get asked this question by a few beekeepers keen to join the Manuka Madness that continues to sweep New Zealand.
How do you tell the difference between manuka “Leptospermum scoparium” and kanuka “Kunzea ericoides”? If you can work this out then it makes it easier to determine what locations may have more Manuka.
Here are some tips you can use, before you move your hives to a new site.
The Crush Test
Kanuka has softer leaves than Manuka, I find when you crush the leaves Manuka has more of prickly feeling.
Flowers (Only works when the trees are flowering)
Manuka has much larger flowers (10-12 mm) than Kanuka (4-5 mm) when compared side by side.
The flowering of both these trees differs across New Zealand. After talking to beekeepers across New Zealand, we learnt the flowering is completely inconsistent and changes from year to year.
Generally Manuka flower before Christmas in December and starts first in the North of the North Island.
Commercial Beekeepers move their bees to follow the Manuka flow down the country.
The Solander method.Daniel Solander was a Swedish botanist on Captain Cook’s first voyage in 1769 to New Zealand. He used to use a Rule of thumb method to determine if the plant was Kanuka.
Take some bark and rub in your fingers, is the tissue is soft and smells strongly then you can be sure its Kanuka. If the tissue is harsh to the feel and without scent or only mildly aromatic the tree will probably be Manuka.
The Height Check
Kanuka have a faster growth rate, trees reach 10-15 meters tall.
Whereas Manuka generally stops growing at 6-8 meters high.
