How to Propagate Bougainvillea in Water: A Simple Step-by-Step Guide Want more bougainvillea plants without spending a dime? Try this easy and natural method of growing new ones from cuttings just using water! 1. Choose healthy stems Pick young, healthy stems from your bougainvillea that arent flowering. Avoid old or woody branches. 2. Prepare the cuttings Cut 1520 cm 68 inch sections, each with at least two nodes the little bumps where leaves grow. Remove the leaves from the bottom half of each cutting. 3. Place in water Put the cuttings in a clean glass or jar of water. Make sure the nodes are fully submerged, but keep the leaves above the water line. 4. Keep the water fresh Change the water every 23 days to prevent mold and keep it well oxygenated. 5. Wait for roots to grow Be patient after a few weeks, youll start to see roots growing from the submerged nodes. 6. Time to plant Once the roots are about 510 cm 24 inches long, transfer the cuttings into pots with light, well-draining soil. 7. Gentle care in the beginning Place your new plants in a sheltered spot with bright, indirect light. Keep them protected from strong wind or direct sun until they adjust. Thats it! This method is simple, rewarding, and a beautiful way to expand your garden with more bougainvilleas.
