I have it out in full sun but at certain times of the year it gets a bit of afternoon shade from a tall Eucalyptus about 15mts away I keep it well watered in the heat and dry but I have never fertlised it, could this be the reason for not much growth, or would it be better if I moved it to a shadier spot on my block.

I have recently planted a Backhousia myrtifolia "Grey Myrtle" and three weeks down the track is showing signs of growing already, but this one I planted where it will get a bit more shade among lots of other recently planted taller trees where I am hoping to make some kind of rainforest, so would it be better if I moved the "Lemon Myrtle " to this spot, if yes then would it be OK to move it now as I dont think it would have grown much in the root department.

Looking forward to your Help.....MM.

Close up of Lemon Scented Myrtle.

I've grown one in Brisbane in full sun, no problems, even with adjacent trees for competition. The only difference from yours is that it was on a slightly raised bed, in a good loose soil. Is the soil at yours a heavy clay? Maybe it is having trouble getting its roots down?

I have one now about 4m high in the Toowoomba area, not in a raised bed but with loamy clay soil and mulched. Recently it was looking a bit stressed because of the drought so I had to water it, and it has recovered.

A couple of the leaves on yours look a little yellow, is there a soil mineral deficiency? They are fairly robust trees and this should not normally be a problem, but you never know.

Otherwise I would just water it weekly, if and when you see some tip growth (which seems to be happening now), and just be patient.

Good luck,
Frank.

Frank thanks for that info, mine is also in a raised square meter only about 12cms high but due to the hard compacted soil I have on my block nearly all my trees are raised so I get a good mix together before I plant, adding wetta soil and gypsum the top 30cms of our soil is not too bad when it is moist but below that it is hard baked clay.

I will give it some trace elements actually I will even test the ph tomorrow, as you can see it is well mulched so I dont know why it has not been growing, could be lack of rain, but as you said tip growth is happening now, should I tip prune it soon to make it bushier or leave it till it gets a lot bigger or dont do it at all, I will try to be patient too Cheers .....MM.

I do tip prune some of my plants, but never the Lemon-scented Myrtle. It forms into a well-shaped plant all by itself and there is absolutely no need to tip prune it.

Cheers,
Frank

And I will keep mulching. Cheers and Happy Gardening.
MM.

So if you have a poor performing lemon myrtle, prune it back to a twig. Either it will pick up its act or it will die (in my case, not a loss, as a 3 leaf plant isn't work keeping). I think the problem was some pest. Once I removed all the leaves the pest died and plant took off.
