Q.Why won\’t my crepe myrtle flower?
I grew my crepe myrtle from a cutting four years ago. It is now 150cm tall and we are in mid-summer but it shows no sign of flowering. It is in a north west facing position (in the southern hemisphere), in full sun and it looks to be growing vigorous. I even gave it a light prune last autumn. Will it every flower?
Isn't that a flower I see in the second photo? And maybe some unopened buds. Give it more time, it's still quite young.
The grass is very competitive for water and nutrients. I recommend clearing a one meter radius for the root zone, fertilize, mulch and deep water in this area.
But I recommend a slow release complete organic fertilizer like this:
