Propagation of Wahlenbergia bowkerae Sond.
Wahlenbergia bowkerae Sond. is commonly propagated by seed. However, vegetative propagation can also be successful in some cases.
Seed propagation
The plant produces small seeds that can be collected when they have turned brown. It is essential to ensure that the seeds are mature before harvesting, as immature seeds will not germinate. After collecting the seeds, it is advisable to store them in a cool, dry place before sowing them.
The seeds should be sown in a well-draining planting mix. It would be best if you covered them lightly with soil, as they require some light to germinate. The optimum temperature for germinating Wahlenbergia bowkerae Sond. seeds is between 15-18°C.
The seeds usually germinate in two to four weeks. Once the seedlings have reached a considerable size, they can be transplanted to individual pots or directly into the garden.
Vegetative propagation
Wahlenbergia bowkerae Sond. can also be propagated vegetatively by stem cuttings. The best time to take the cuttings is during the plant's active growth period, which is usually in the spring or summer.
Using a sharp, sterilized knife or scissors, cut a 7-10cm stem section from the parent plant. It is essential to ensure that the cutting is taken with a flaring portion of the parent stem to promote rooting.
Dip the cutting in rooting hormone and insert it into a well-draining potting soil mix. Water the cutting well and cover it with a plastic bag or a cloche to maintain high humidity.
Place the cutting in a bright, warm area and check it regularly to ensure that the soil is moist and that the humidity is maintained. The roots usually develop after four to six weeks, and the new plant can be transplanted to a larger pot or into the garden.
