For the weeds depicted above and left, the best means of removal is pulling them out. Disturb the soil as little as possible. Take care to remove all (or as much as you can) of the plant, including its roots. (Many species will re-grow from even broken pieces of the plant left on the soil.) Dispose of the weeds removed at the green waste tip. Chemical weed control is also possible.

Guinea grass (Panicum maximum) (right) is possibly the most widespread and common weed on Magnetic Island, taking over entire cleared blocks and requiring regular slashing. Along roadsides, it can cause a barrier, preventing wildlife from fleeing on-coming vehicles or predators. The best approach is to pull out clumps of guinea grass. Moistening the soil first will help. Disturb the soil as little as possible. Shake soil from roots. Use the grass as mulch around trees, making sure that the roots are not in contact with the soil. Regular slashing, mowing or brushcutting may discourage string growth. Chemical weed control is also possible. |
