Troubleshooting
Forrest Ginger Lily problems — and how to fix them
Forrest Ginger Lily (Hedychium forrestii) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Frost damage to emerging shoots
Late spring frosts can blacken newly emerging shoots. In frost-prone areas, apply a thick mulch over the rhizomes in autumn and remove in spring. Cover emerging shoots with fleece if late frosts are forecast.
Slug and snail damage
Young shoots are highly attractive to slugs and snails. Apply organic slug pellets or copper barriers around the emerging growth in spring.
Failure to flower
Insufficient sun, a too-shaded position, or poor feeding commonly reduce flowering. Ensure at least 4 hours of good light and consistent feeding from spring.
Root rot in wet winter conditions
In heavy, waterlogged soils, rhizomes rot over winter. Improve drainage or lift and store rhizomes frost-free until spring.
Aphids on flower buds
Aphids cluster on the developing flower heads and buds. Blast off with water or apply an insecticidal soap spray.
