The most common cause of plant loss; M. lanceolata demands sharp drainage and dies quickly in waterlogged or heavy clay soils. Plant on a slope or raised bed and work in ample grit to prevent water pooling around the crown.
Aphids
Colonies of green aphids can disfigure the soft spring foliage and flower stems. Knock off with a strong water jet or treat with an insecticidal soap spray; the plant dies back naturally by midsummer, limiting the season of exposure.
