Optimum results are achieved when the plants are grown in the best possible soils, weed free, fertile with adequate drainage. Ground preparation by spraying out existing lawn or weeds. Generally Roundup or a similar Glyphosate product will do the job but it may need 2 or 3 sprays. Removal of the old lawn turf is preferable as grass is very persistent when you don’t want it to be.
Plants are sent in trays and you cut plugs out of these with a strong sharp knife. We gently invert the trays, with a little shake plus a bit of leverage the mass falls out and then we to cut them into 6 strips side ways then into 5 plugs giving you plugs of approx. 80mm square.
The plugs are planted so the base of the leaves are level with the soil (make sure the soil is packed firm so it doesn’t drop) at around 200mm apart which will cover approx 2 m2. The closer they are planted together, the quicker the whole matt will form but it comes at a higher input cost. See the image above.
A slow release fertiliser applied at planting is beneficial and we use Bio Boost (although there are other products that will do a similar job) which is available through FruitFed or PGG Wrightson stores at a very economic rate ($36 for a 25 kg bag as at Jan 2014).
Watering the plugs and weeding around them is essential in establishing the plants. Once the plant has formed a matt this in turn acts as a form of weed suppressant but nothing is 100% bullet proof, weeds will still appear occasionally.
For Selliera, salt purchased in the form of AgSalt (fine rather than coarse) around $14 for a 25kg can be used to kill off weeds. This is applied by sprinkling over the weeds after a heavy dew or irrigation.
Selliera grows naturally in tidal estuaries so requires regular watering and good drainage. The tips can brown off under stress which could be from lack of water, poor drainage or frosts. Research states that it is hard to define the difference between Selliera microphylla (fine) & Selliera radicans (more shaped like a propeller on a plane) and that plants can range from one into the other. We will send trays from the same batch but can’t guarantee they will stay true to form not that there is much variance.
