Propagation from seed is possible in bamboo species that produce external seeds. If you have your own plants, watch seed production closely, as mature seeds that ripen and fall to ground will be eaten by rodents and birds. The seeds do not store well and require immediate germination for best results. If it is necessary to purchase seeds, make sure it is good quality seed from a reputable source.
Collect seeds from the bamboo plant or purchase quality seeds from a retailer.
Rinse the seeds in clean water. Soak them in a solution that is a 10 percent salt water solution for five minutes. Rinse the seeds well and soak in clean water for an additional 15 minutes.
Create a seed starting soil by mixing equal quantities of perlite and peat moss. Moisten the soil lightly so no water can be squeezed out.
Fill a seed starting tray with the seed starting soil and randomly scatter the seeds on top of the soil.
Lightly cover the seeds with seed starting soil. Place a clear plastic covering over the tray to keep the moisture inside the growing environment. Place the tray in a warm location with indirect sunlight.
Open the cover one to two times a week to check the soil moisture and aerate the plants. Gently mist the soil with clean water if dry.
Keep the cover on the tray until seedlings appear and reach the top of the cover. Germination will take approximately 2 to 3 weeks.
Apply an all-purpose fertilizer that is water soluble after one month of seedling growth. The fertilizer can be misted onto the plants using a spray bottle on the mist setting.
Transplant the seedlings to 4-inch pots after they are more than four inches in height. The seedlings can be transplanted outdoors after two to three months of growth.
