Bamboo seeds are a rare find due to the bamboo's tendency to flower between extremely long intervals. While many people have a high percentage of bamboo germination rates, the seedlings are extremely fragile once they are grown. The seeds must be prepared in a precise manner and need to grow in a humid and semi-sunny environment. Growing bamboo from the ground up can be difficult and even frustrating, but a successfully grown plant can be a gardener's proudest achievement.
Obtain seeds from a local supplier or order them online. Bamboo seeds are rare so the Internet may be your best option for finding them.
Rinse the seeds in clean water. Fill a pot with a 10-percent salt water solution and allow the seeds to soak for 5 minutes. Move the seeds to clean water and soak them for 15 minutes.
Fill a large Tupperware cake pan three-quarters of the way with an equal mix of peat moss and perlite. Water the soil under it is extremely moist but not soaked. Squeeze the soil in your hand. If only one or two drops of water exit the soil, the soil has been watered in the right amount.
Lay the seeds over the soil. Each seed should be 3 to 5 centimeters apart. Cover the seeds lightly with the remaining soil mixture and seal the pan with the lid.
Wait 2 to 3 weeks for sprouts to appear. Once every week, open the lid and allow fresh air to enter the container. Also, check to ensure the soil is still wet. Add more water if needed. The air-tight lid of the container will keep moisture in, making the perfect high humidity environment for the seeds.
Allow the sprouts to grow until they touch the top of the lid, usually one week after the initial sprout sighting. Remove the cover and allow the seeds to continue growing in the container for 3 to 4 weeks. The container must be placed in partial sunlight in an area with moderate temperatures. A sunny window is best.
Transplant the sprouts after they have grown in the container for one month. You may need to transplant early if your sprouts become crowded. Their root systems grow extremely fast and require room to branch out.
