Olearia

Exposure

OleariaFor best development, this plant should be placed in a sunny position, or it can resist even in a half-shade position.

If it is grown in too shady positions, it is likely that the plant will show a poor flowering; this genus includes a hundred species, many of which cannot survive in our climates, but in general the species grown also in Europe can easily withstand temperatures just below zero; during particularly cold winters it is good to repair the plants, to avoid burns due to frost and it may be useful to cover the surrounding soil with leaves and straw or mulch to protect the roots from too harsh climates.

To maintain a compact vegetation it is good to prune the plant vigorously after flowering.

Watering

olearia From March to September, the Olearia nummulariifolia should be watered regularly, allowing the soil to dry up a little between one watering and the other; too little watering can compromise flowering.

In the vegetative period it is useful to add to the soil of the Olearia nummulariifolia a fertilizer for flowering plants to the water of the watering, every 10-15 days.

Land

olearia erubescens The Olearia nummulariifolia should be planted in rich and very well drained soil, possibly enriched with mature organic fertilizer and lightened with sand and pumice stone, so as to ensure proper drainage and the correct degree of humidity.

Multiplication

The multiplication of the Olearia nummulariifolia can take place by seed, at the beginning of spring; in late summer, semi-woody cuttings can be produced, which are to be immersed in the rooting hormone before being placed to root in a container filled with sand and peat in equal parts; keep humid and in a shady place until the rooting has taken place. The new plants obtained are planted the following year so as to allow them to acquire the right strength to resist the transplant.
