My pecan started getting brown tips on the leaves at the end of it's growing season the year before last and it's progressed to the emerging spring leaves.
Hi Seleni, thanks for the reply.
My location is South Western Australia.
The pH of the soil I planted it in was around 7. It is high compost "bedding mix" made by a local company, something like a standard potting mix. I made an addition of mixed, composted manures of the spring on the season the brown tips started. The surrounding soil is barren, Australian grey sandy topsoil. The average pH of my property is around 7 also.
It's in full sun and has an olive tree 10m on one side and an endemic Hakea 10m the other side.
It's in a location that is 20m away from where there used to be a 40foot high and wide eucalypt tree that was at least 6 feet wide at the base. The stump has been removed but there are residual root systems remaining.
I have it mulched with mixed species wood chips and around the base planted spring onion, fushia and burdock.
Last week I made the addition of pig manure around the base and watered it in well.
That's about as detailed as I can get I think.
I have ash from my tile fire that we use to warm the house and cook bones from meals in. Will that do?
I also have a detailed reply to Seleni here regarding it's environment: https://aussie.zone/comment/13041834
