I have a one year old hebe that is looking very sorry for itself. I
called the garden centre and they suggested i cut the stalk to check it
ws alive, and it is green so I presume that's a yes. However it is very
sparse, all the bottom leaves have dropped off and the top ones are
hardly what you'd call shiny. Some are half brown.

What should I feed it to try and perk it up

cheers
