Propagation of Dombeya kituiensis Baill. ex Hochr.
Dombeya kituiensis Baill. ex Hochr. can be propagated through two main methods, namely seed propagation and vegetative propagation.
Seed propagation
Seed propagation is the easiest and most preferred method to propagate Dombeya kituiensis Baill. ex Hochr. Collect matured seeds from the parent plant and make sure they are free from pest and diseases.
Clean them by rubbing the seed coat gently with sandpaper, and then soak them in water for at least 24 hours. This will help to soften the hard seed coat and improve germination.
Afterward, plant the seeds in a well-draining soil mix and cover lightly with soil. Water the soil gently and keep it moist. Place the planted seeds in a warm and bright location, away from direct sunlight. Germination will occur within 3 to 4 weeks.
Vegetative propagation
Dombeya kituiensis Baill. ex Hochr. can also be propagated vegetatively using softwood cuttings, semi-ripe cuttings, and hardwood cuttings.
Take a cutting of healthy plant material; ideally, it should be a young stem with 3 to 4 nodes. Remove the lower leaves and dip the base of the cutting in rooting hormones. Plant the cutting in a well-draining soil mix and water well. Place the cutting in a shaded location, away from direct sunlight. Make sure to keep the soil moist.
Rooting should occur within a few weeks. After root formation, transplant the new plant into a container with well-drained soil and place in a bright location, away from direct sunlight. Water the plant regularly and fertilize occasionally to encourage healthy growth.
