Propagation of Oldenlandia oxycoccoides Bremek.
Oldenlandia oxycoccoides Bremek. can be propagated through seeds or cuttings.
Propagation through Seeds
The seeds of Oldenlandia oxycoccoides Bremek. are small, brownish-black, and oblong in shape. To propagate through seed, collect the fully ripe seeds and sow them immediately in a well-draining soil mix. The seeds need to be barely covered with soil, and the container should be kept at a temperature of 21-25°C until germination, which usually happens in about two weeks. Once the seedlings are big enough to handle, they can be transplanted into individual pots or a larger container.
Propagation through Cuttings
Oldenlandia oxycoccoides Bremek. can also be propagated through stem cuttings. Select a healthy, mature stem from the parent plant and cut a section that is about 10 cm long, with at least two nodes. Remove any leaves from the lower half of the stem, leaving only a few on the upper half. Dip the cut end of the stem in a rooting hormone and plant it in a well-draining soil mix. Water the cutting and cover it with a plastic bag to create a humid environment. Place the container in a bright, but not direct, light and maintain the humidity until roots start to develop, which usually takes around four weeks. Once the roots have formed, the cutting can be transplanted to a larger container or individual pots.
