Care:
Care: Catmint is one of those plants that thrives on neglect. Many
of the newer varieties of Nepeta are sterile hybrids that produce no
viable seeds; a benefit if you don’t like the weedy, self-seeding habit
of older catmint varieties. If you want to increase the number of
catmint plants, the lack of viable seeds mean that you will need to
either buy more plants or propagate new plants from divisions or
cuttings.
Disease: Catmint is rarely bothered
by any pests and diseases. The plant is low-maintenance and easy to
grow and propagate, some of the many reasons catmint is so popular with
gardeners.
Propagation: Catmint plants will
gracefully spill over walls and walkways. Most catmints will
repeat-bloom if they are sheared back after their initial flowering.
Some won’t provide much of a second show, but their foliage will be
refreshed and tidied by the shearing.
