Troubleshooting
Pineapple Mint problems — and how to fix them
Pineapple Mint (Mentha suaveolens 'Variegata') 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.
Variegation reversion
Patches may revert to all-green and outcompete the variegated growth; cut out plain-green shoots as they appear.
Mint rust
Orange spore pustules under leaves; remove infected stems, thin for airflow, and water at soil level.
Leaf scorch
The soft variegated leaves brown at the edges in harsh sun and dry soil; site in dappled light and keep moist.
Spreading runners
Though milder than spearmint, it still creeps; contain in pots or sunken edging to keep beds tidy.
