Agonis Flexuosa Cultivars and varieties

Agonis flexuosa ‘After Dark’ is a newer release again with beautiful burgandy foliage. These two will reach around 4m ( more or less depending on conditions) and both make excellent container ot pot grown plants. A variegated form is also available.
Leaves turning brown and dying can be caused by a number of issues on Agonis species and cultivars.
- To much water.
- Insects – Mites and Scale.
- Soil to alkaline.
The most likely problem is insect infestation.
Check the foliage very careful for any sign of insects.
- The mites are very small so magnifying glass may be needed to actually see them. However the underside of the leaves become covered with a very fine web and you can often see the little clearish white eggs.
- Scale is like a fungus caused by insects. Often called ‘Sooty Mould’, usually you can see this on the underside of the foliage.
Treatment for both is spraying with a Horticultural oil, (white oil) or Horticultural soap Natrasoap, on a cool day.
Check with you local nursery for these and how to apply them. Spray from beneath the foliage as usually the insects are on the underside of the leaves.
