Propagation of Wahlenbergia kilimandscharica Engl. var. intermedia Brehmer
Wahlenbergia kilimandscharica Engl. var. intermedia Brehmer, commonly known as the Kilimanjaro blue or the Tanzanian bluebell, is a perennial plant species found in high altitude regions of Tanzania, Kenya, and Uganda.
Propagating the Wahlenbergia kilimandscharica is possible through vegetative propagation and seed propagation.
Vegetative propagation
The vegetative propagation of Wahlenbergia kilimandscharica is achieved through cuttings. Stem cuttings are taken from the parent plant, and the bottom leaves are trimmed off, leaving one or two pairs of leaves at the top. The cutting is then inserted in a rooting hormone solution and later planted in a well-draining soil mix.
Rooting hormone is used to stimulate the growth of roots, which is crucial for the survival of the cutting. Bottom heat may also be applied to the potting mix to provide optimal conditions for the cutting to root. The ideal temperature should range between 20-25 degrees Celsius.
A humidity dome or a clear plastic bag can be used to cover the cutting to reduce moisture loss. The cutting will develop roots within six to eight weeks, and the plant can then be transplanted into a potting soil mix or the garden bed.
Seed propagation
Seed propagation of Wahlenbergia kilimandscharica is also possible. Seeds can be purchased or collected from the plant when it fruits. Lightly press the seeds onto the surface of the soil mix in a container or tray and cover with a thin layer of soil mix.
For the seed to germinate, optimal conditions for growth must be provided. The ideal temperature for germination is 20-25 degrees Celsius. Proper watering is also crucial for seed germination. The soil should be kept moist by misting or spraying with water periodically.
Once the seedlings emerge, the cover should be removed to provide adequate light. They can then be transplanted into a potting soil mix and grown to maturity before being transplanted into the garden bed.
