Tobacco plants require consistent moisture, especially during active growth and flowering. Water deeply when the top few centimeters of soil feel dry, but avoid waterlogging.

Reduce watering slightly as the plant matures and approaches harvest, but do not let it completely dry out.

Topping, the removal of flower buds, is a common practice to encourage larger leaf growth and prevent seed production.

Suckering involves removing side shoots that emerge from leaf axils, which also directs energy to the main leaves. These practices are crucial for commercial tobacco production.

Tobacco is primarily propagated by seed. Seeds are very small and typically surface-sown indoors 6-8 weeks before the last frost.

Transplant seedlings outdoors after all danger of frost has passed and soil temperatures have warmed. Cuttings can also be rooted, but seed is more common.

For plants grown in pots, repotting may be necessary if they outgrow their container. Choose a pot only slightly larger than the previous one to avoid overwatering and ensure good drainage.

Most tobacco is grown directly in the ground as an annual, so repotting is less common for its primary use.
