I have 2 grevillea plants that look like they have mould on them. They are growing but they do not look healthy. They are Grevillea 'Limespider' and Grevillea 'Honey Gem'. I do not water them very often, however we have had alot of rain. Both plants have looked sickly from the time they were planted.
I also had 2 grevilleas which died. They were Grevillea'Poorinda Beauty' and Grevillea 'Yamba Sunshine'. These were attacked by a sap sucker variety and thrips. They went from healthy florishing plants to dead within 5 days. I treated them with rogur which saved them a couple of times, but in the end it didnt.
I have other varietys of grevilleas in the garden that are growing really well. All of the grevilleas are less than a year old.
Does anyone have any ideas re the mould and how to prevent my healthy grevilleas from being attacked ie companion plants?
I live in Mackay, QLD.
