Silky oak stock material

[MattA]

In general the branches have nice exit lines from the trunk then just want to go up. I have just been using selective pruning on mine but its still hell to get them to stay down. I think i will have to cut off all the branches and start again, no matter I have plenty of time. I didnt think it would even transplant from my neighbours yard, at the time i couldnt find any info on them at all, except on how to eradicate them as weed seedlings LOL

Hi Eddie
silky oak seem to handle pot culture well.
As they are a grevillea, it is not surprising that hitting them with regular fertiliser can do them harm. I've not checked their roots for those special 'proteoid roots' that are so good at scavenging nutrients from low nutrient soils, but end up killing the plant when offered a super abundance, especially of phosphate. I suspect that is what happened with your tree. Use low phosphate fertilisers and you will be ok.

Agreed grevillea's and phosphate just do not agree!
