How can I propagate bougainvillea plants successfully?

To propagate bougainvillea plants successfully, you can use stem cuttings. Choose a healthy stem, cut it at a 45-degree angle, remove the lower leaves, and plant it in well-draining soil. Keep the soil moist and place the cutting in a warm, sunny spot. After a few weeks, roots should develop, and you can transplant the cutting into a larger pot or garden.
