[Vetiver Grass / Grow Vetiver ] Bagging a Vetiver Hedge

 

These are hessian bags filled with the sandy soil we have under foot in our nursery which is also in our poultry run.  When digging,  it's black on top, through grey to yellow pure sand at 30cm depth.

The line is just over 3 metres long using 5 hessian bags which cost $2 each (that's not a bulk buy, just the going retail price)

The bags were each filled to 75% capacity.

Each bag was pieced 4 times and Vetiver slips inserted-- along with a scattering of composted manure.

We plan to give the plants a few weeks for their growth to consolidate before moving them into position on the seaside -- above the King Tide line/on the edge of the reach of the last storm surge. This is an experimental project as storm surges have carried away our earlier attempts at planting vetiver in sand on the Moreton Bay shoreline. 

If we lay the bags along the contour into a shallow pre-dug trough and stake each bag with a 80cm tall picket,  maybe we can be hopeful the plants will survive long enough to thrive. 

By starting back from the shoreline -- and thereby allowing the slips a better chance to survive --  our hope is we can then look to planting further bagged slips in from of this hedge line as the sand begins to consolidate. 

In the past we found that the hessian bags when filled, tended to rot at a rate that limited their utility. To use the heavier weave gunny, coffee or potato sacks, requires they be split in half and re-sewn  in order to replicate a stronger bag of the same size as these sand bags. Same final cost (each sack costs approx $4) before division  as the sand bags. 

Whole gunny sacks used instead of these hessian sand bags are simply too heavy to be a feasible option. 

If the experiment proves succesful, our notion is to encourage this Vetiver + bag combination as an option for those sites prone to flash flooding or storm surge over-run.
