Propagation of Begonia sutherlandii Hook.f. subsp. sutherlandii
Begonia sutherlandii Hook.f. subsp. sutherlandii can be propagated through various methods such as stem cuttings, leaf cuttings, and division.
Stem cuttings
To propagate through stem cuttings, select a healthy stem with several leaves. Cut the stem just below a node and remove the lower leaves. Dip the cut end in rooting hormone and plant the cutting in a well-draining soil mix. Water the soil and cover the cutting with a plastic bag to create a humid environment. Keep the plant in bright, indirect sunlight and provide sufficient water and nutrients. The cutting will root in about 4-6 weeks.
Leaf cuttings
For leaf cuttings, select a healthy leaf with its petiole. Cut the petiole to about 2 inches and insert it into a well-draining soil mix. Water the soil and cover the cutting with a plastic bag to create a humid environment. Keep the plant in bright, indirect sunlight and provide sufficient water and nutrients. The leaf cutting will root in about 4-6 weeks and small plantlets will emerge from the base of the leaf.
Division
To propagate through division, carefully remove the plant from its container or garden bed and gently separate the rhizomes into smaller clumps. Each clump should have enough roots and shoots to form a separate plant. Plant the clumps in well-draining soil mix and water thoroughly. Keep the new plants in a bright, indirect light with sufficient water and nutrients. The new plants will establish in about 4-6 weeks.
