Maybe the mulch is drawing lots of nitrogen from the soil. 3in1 Supadiverta. Rainwater Harvesting Best Practice using syphonic drainage. Cleaner Neater Smarter Cheaper Supa Gutter Pumper.

Maybe the mulch is drawing lots of nitrogen from the soil. Thanks, the top of the root ball is level with the mulch layer ie. the trunks aren't covered. But I will try that. The mulch is composted forest mulch which is not supposed to draw any nitrogen from the soil at all as it's already staring to decompose. At least that's what the treeloppers said. Re: Tree leaves are yellow green but should be red 4May 10, 2017 7:31 pm Do you have a close up on the specimens? I'd say, and it's just a theory but the new growth isn't too dense, but rather spindly. The theory is, that you may need to prune back to encourage more dense growth and any new growth has protection so its color stays red longer. I have two varieties of australis and while they are similar, the red foliage is more pronounced in the resilience variety than the Aussie southern, which sounds a similar variety to what you describe. If the pruning doesn't improve, I would go back to the nursery you purchased them from and show them pictures and some sample pruning to compare to the variety you thought you purchased. I must also say that the recent rains encourage the very green growth rather than red. How's the rainfall been at your place in the last month or so?

That's a good theory, we haven't pruned at all since we planted them in November. I'll grab a closeup in the morning. The red growth was visible on the trees when they were delivered so I'm pretty confident that they're the correct variety, and I spoke to the nursery owner on the phone about suitability prior to purchasing (they created this variety at their nursery so they're the experts!). I've sent them photos as well asking for advice but no dice yet. We had heaps of rain in the first few months of the year which kicked off all this growth, good to see but I'd prefer the red colour!
