My Bottle Brush (Callistemon) shrub won't grow
I have a bottle brush, the old red variety, it is planted in loamy soil, about 16 mths old and about 1 ft high. It sat there for yonks until about 6 months ago it had a small growing spurt sprouting lots of new leaves and it hasn't done anything since. It looks healthy enough, it just won't grow. Should I give it a light ? heavy ? pruning to shock it into action or what should I do. It is in a semi-shaded position. I live in mid-west qld and am on bore water but I feed it rain water.
Any help with this would be greatly appreciated.
