Important: Spearmint spreads through underground rhizomes. Growing it in a separate grow bag helps prevent unwanted spreading into surrounding garden beds.

Recommended Soil / Potting Mix

50% Bhalu Mitti / Garden Soil + 30% GREEN GARDENS Vermicompost + 20% Cocopeat.

Use loose, fertile, moisture-retentive and well-draining soil.

Maintain consistent soil moisture without prolonged waterlogging.
