Grevilea robusta tree yellowing

#1 · 15th September 2024, 5:48 am

I have a grevilea robusta oak and in the past 3-4 months it started turning yellow and its leaves are going brown. I am living in Cyprus and its quite hot and its not a problem of overwatering. Any suggestions as to how to save her would be very much appreciated.

Hi @erik

Thanks for your comment. Can you give some more detail, like when it was planted (how old it is) and what soil type it's on?

From initial glances, it looks like mottling from chlorosis and then some scorch, but other information would help!

All the best

Lee

Thank you so much for the reply. The tree is about 2-3 years old. The soil is clayish with poor drainage. I have already sprayed with aliette fungicide on the leaves and i have put some added iron on the roots as well. Do you think there is is something else i can do?
