I am up to spike number seven with the 1st 6 always blasting. I'm kind of hoping that it's just too young and too eager, rather than me being at fault!!
Spike number 6 got to be twice as long as the preceding 5 before it blasted, hopefully spike number 7 will make it through. It is a prolific spiker.
The plant is otherwise healthy and happy but stands about 15-20cm in height.
