Shrub Trimming with Brush Cuttter

Amidst the pressing draught of labour, every task and worker are closely monitored to ensure maximum productivity.  

A brush cutter is designed for trimming and cutting grass and brush.  Yet, in Malaysia, we seldom see a brush cutter being used to trimming brush / bushes / shrubs / scrub / thicket.  

Thus, brush cutters were used in trimming several shrubs, e.g. Hibiscus rosa-sinensis, Ixora javanica, Bougainvillea  glabra etc.   The result was fantastically fast.   Time spent on trimming was cut half !   The task would be even faster when the workers familiarized themselves with the machine. 


The ideal height of the shrubs should be around or less than 1 meter.  Otherwise, an elevated platform is required, which is very inconvenience, dangerous and time-dragging.

Neptunia plena

Taxonomy

Neptunia plena are a member of the Mimosoideae subfamily of Fabaceae family(1).

When I first encountered this yellow 'Mimosa', I was thrilled to have discovered an exotic species. Obviously, I was wrong assuming that it is a Mimosa. However I was not entirely wrong, at least, as it is indeed a cousin of Mimosa, from Mimoseae tribe(2). Some even name it Mimosa plena, M. punctata, M. adenanthera, or M. lycopodioides as well as many other names (3) .

It is after a long time then I realized that it is actually Neptunia plena 假含羞草 , also known as Aquatic-Dead-and-awake. Thanks to 1001 Garden Plants in Singapore, 2nd Edition. It puzzled me though : who would plant it as a garden plant in the first place. No doubt that the flower is somehow pretty, but not till that extend of bringing it home ! I wouldn’t , for sure.


Distribution

Originated from the tropical America : Texas, Costa Rica, Honduras, Nicaragua, West Indies, French Guiana, Guyana, Suriname, Venezuela, Ecuador, Peru, Paraguay (2). It is now naturalized in tropical Asia (2), becoming a noxious weed, invasive and hard to eradicate.

Botany

Neptunia seems to be water-loving, perennial herbaceous shrub (3). Leaves evenly bipinnate, mildly sensitive to physical touch; glabrous stem; the flower is actinomorphic, numerous stamens, globorous ; pods dehisces when matured (4).
