Watering

diuris corymbosa Water regularly from October to May, allowing the soil to dry up a little between one watering and the other and checking that no water stagnation forms in the soil, which can lead to root rot. During the remaining months of the year, if the plant is left warm, it is better not to water; during the vegetative period, provide fertiliser for orchids, every 25-30 days, dissolved in the water of the watering.

Land

diuris sulphurea These orchids grow in a fertile, deep and well-drained soil; use the well-drained orchid compound, mixing a high percentage of leaf and peat soil, and a small handful of mature organic fertilizer.

Usually the diuris develop large colonies, as the tubers tend to expand underground and to produce new plants continuously; if you want to grow these beautiful orchids in pots is good to remember to use a large container, or often divide the tubers.

In the case of cultivation in containers, it is therefore advisable to provide for a constant repotting, during the vegetative rest in order to avoid causing suffering to the specimens.

Multiplication

If desired, it is possible to propagate the Diuris by detaching from the tubers portions provided with some well developed roots: the new plants thus obtained are to be immediately buried in the ground, utilizing a fertile and well drained soil.
