Harvest Tips
Pinch off leaf sprigs as needed starting 4-6 weeks after planting; harvest in the morning after dew dries for best flavor and aroma. Remove leaves from the top down to encourage bushier growth. Cut no more than one-third of the plant at a time. Regular harvesting promotes vigor and prevents flowering. Best flavor before flowering.
Fun Facts
- 🌱 Scrub mint is native to rocky hillsides and semi-arid regions of South Africa, making it exceptionally drought-tolerant compared to common mints.
- 🌱 The plant's exceptionally powerful aroma is due to higher concentrations of menthol and other volatile oils, making it one of the most intensely scented mint species.
- 🌱 Unlike many aggressive mint species, scrub mint is more contained and less likely to take over a garden, making it a better choice for mixed plantings.
