Cutting back lemongrass
We have several large clumps of lemongrass which have largely died off, probably due to the cold winter. How do I deal with them? There are some new stalks growing amongst the dead ones. Do I just cut it all back, or should I be pulling out the roots of the dead lemongrass? I don't wish to replant any, as we have ample. But I would like to see the present clumps healthy.
Yes pull out the roots of the dead lemon grass so that the new shoots have root space. You can also prune off dead ones leaving the dead roots in to decompose, not the best approach however.
