One of the native irises that does well for a border and is so very rewarding. Flowers individually are not the longest lasting, though the plant gives for an extended period in the right conditions.

Goodenia trinervis is traditionally more happy in WA but is thriving in Melbourne.

Anyone else having success on the east coast with this one?

Hi, about 5 years ago when I bought this house and had the land cleared (was full of weeds and junk) I planted a bunch of various Grevillea around the yard including this ‘Moonlight’ I have going, currently struggling, maybe the last 6 months, is this too late to save? As you can see there is an issue with either iron or magnesium uptake from the fertiliser (Neutrog Bush Tucker).

I live in outback South Australia, our soil here is quite arid, calcareous, pH of 7.5+, so meaning ideally ‘Moonlight’ wasn’t suited for this area to begin with when I planted it, although has been doing well until the last day 12 months, some stunning huge white flowers that the birds, bees and ants love.

Instead of ripping it out, I’ve now learned more about what I can and can’t plant here in these soils, the soil conditions, so here is what I’ve done to try and salvage it.

I’ve trimmed back about a month ago, Grevillea respond well to trims, some say heavy, I’d say I cut back a quarter, I’ve put a generous amount of elemental sulfur around the area of the Grevillea, sulfur drops the pH in the soil over time, I’ve today bought some bags of Debco Native Potting Mix, it’s all I could get in our area in regards to Native soils, I’ve put 2 bags around the area of the Grevillea, turned the soil over and given a watering in via water can of 9l of water mixed with Eco Seaweed, so now I’ll sit back and see if it recovers.

I’ve also ordered a bottle of Growth Technology Iron, a EDDHA iron chelate which works in high pH soils like mine.

What are the chances it’ll bounce back, too far gone you think?
