Set fire to your Cannas!
 

Reading bits of "Roses love Garlic" I saw a passage that says burning Canna
leaves in a bucket in a greenhouse is a great help in ridding it of
whitefly, aphids etc. The writer suggests getting a metal bucket and
putting rolled up newspaper in the bottom. Then put a piece of mesh across
the top of the bucket and Canna leaves on top of the mesh, having lit the
newspaper. The idea is to get the leaves to smoulder gently, filling the
greenhouse with smoke.

Are they supposed to contain some sort of insecticide then? Wouldn't
surprise me because they seldom seem to suffer with aphids etc. Just slugs
when small.
