leaves turning purple
you tell me why my potted catnip has now gone a reddish-purply colour?
It is in a sunny spot and watered, but is looking very limp.
are not quite sure why this is happening. You don´t say how
old your plant is, but as they grow older, they do become scraggly.
After flowering, you must cut off the plants 10 to 12 cm above the
crown before they turn brown. This allows regrowth from the buds
located on the lower stem nodes. Being a perennial, it will grow
back year after year.
Catnip prefers a well-drained
soil in a sunny or shaded position. Water only when dry and feed
every fortnight with a well balanced organic fertiliser.
