Ocimum campechianum prefers consistently moist soil but dislikes waterlogged conditions. Water deeply when the top inch of soil feels dry. Reduce watering slightly in cooler months to prevent root rot.

Ensure good drainage to avoid issues. Overwatering can lead to fungal diseases and a weakened plant.

Regularly pinch back the tips of Ocimum campechianum stems to encourage bushier growth and prevent premature flowering. This also promotes more leaf production for harvesting.

Prune away any yellowing or dead leaves promptly. Heavy pruning can be done after flowering to rejuvenate the plant.

Ocimum campechianum is easily propagated from seeds sown indoors in spring or directly outdoors after the last frost. Cuttings taken from healthy stems also root readily in water or moist potting mix.

New plants will establish quickly in warm, sunny conditions with consistent moisture.

Repot Ocimum campechianum annually or when the roots begin to fill the pot and protrude from drainage holes. Use a well-draining potting mix.

Choose a pot that is only slightly larger than the current one to avoid overwatering issues. Repot in spring before active growth begins.
