We have a number of Grevilleas in our northern coastal Perth garden. They do benefit greatly from having amended substrate. We have long sought help from the Greenlife Soil company in Midland to source native soil concentrate to dig in, and other wonderful products to amend the sand. If you’re in Perth region, we also prepare the planting spot a few weeks ahead: we dig out a reasonably good sized hole, water in iron sulphate and fulvic acid with organic Eco-Wet soil wetter, kelp and fish hydrolysate. Then we back fill, including the native soil concentrate (50:50), a handful of slow release Growsafe fertiliser (good for Grevilleas), humate, straight blood and bone (avoiding the products that are loaded with fillers commonly found in large warehouse supplies), soldier fly fertiliser, Seamungus, and a little worm waste. We give it all a really good water with more kelp, fish hydrolysate and iron sulphate. Then we mulch with pine bark and chunky wood mulch from down south. We water the spot well with kelp or other soil microbe food, like Verigrow, as well. And we water each week with a can, because our water is hard but if we add some of those organics into the can, it softens the water, which is great for Grevilleas. Finally, after four weeks, we plant the Grevillea! There’s a pair of fantastic products from Neutrog called Bush Tucker, and Popul8. We water in the new plants with these products in the watering can and they really do help us get excellent results. The only other thing I would say is, for Western Australian conditions, it helps if we choose Kings Park bred Grevilleas. Even then, chlorosis can be a problem, which is why we use the iron sulphate. (Again, we’ve noticed a big difference between the amazing product at Greenlife Soil and the ones available at the big warehouses, which don’t easily dissolve in the can. Same price.). We added the City Lights Grevillea and the Dorothy Gordon this winter, and they have already kicked in! The City Lights is amazing! The flowers hold for ages and are sooo bright. We actually eventually found ours at the big warehouse in Joondalup, to our huge surprise. It is the most beautiful Grevillea we’ve had since the first Robyn Gordon we planted in the Dandenong ranges nearly fifty years ago! Stunning. Have fun and I hope this has all contributed to the conversation. 👍✨🪴✨
I do love grevilleas, but with heavy clay soil, a flat garden and limited water, they take a lot of work to prepare for and establish. Getting the mounding right takes time and a lot of soil moving! Here's hoping we start seeing some more nectar-loving birds on the property once they get established! Between the grevilleas, the proteas and the isopogons there just has to be a flower they will like!
Impressive content, Gardening Australia. Looking forward to your next upload from you. I smashed that thumbs up button on your video. Keep up the fantastic work! With such a wide variety of grevilleas available, what factors do you think contribute most to a cultivar's adaptability in different climates?
Aw thank you! Hope you enjoy the next ones too 😊 Interesting question, grevilleas really are so varied and there's so many variables that makes them adapted to a specific situation. The ability to tolerate different levels of heat/humidity and moisture are probably the biggest factors, and that's determined by things like leaf shape and structure which controls transpiration, plus many plants in the proteaceae family have super efficient roots!
Honey Suckle Grevillea is my favourite but it's seemingly impossible to find.
Have a ripper mate and stay safe!
Did anyone else notice the wrong location on the map for Mt Coottha in the upper left at the beginning? Apparently its in VIC 😅
Yep 😂
Oops! 😂 Thanks for watching so closely!

why did the location ping at melbourne haha
Oops! Good pick up!
My Honey Gems just keep on dropping dead after abt 3 years ,
I tried grafting to silky oaks but none took
