Propagation Methods
Lobelia giberroa Hemsl. var. intermedia (Hauman) Robyns can be propagated through various methods, including:
Division
Propagation through division involves dividing the mother plant into smaller sections, each with its own root system. This method is best carried out during the spring or winter by carefully removing the plant from its pot or garden bed and separating the root ball into smaller sections using a sharp, sterilized knife or pruning shears. The divided sections should be replanted immediately into pots or a new garden bed, ensuring that they are watered and placed in a shaded area until new growth is observed.
Seeds
Propagation through seeds is a common method of propagating Lobelia giberroa Hemsl. var. intermedia (Hauman) Robyns. Seeds can be obtained from mature plants or purchased from a reputable seed supplier. The seeds are sown in the spring or winter by scattering them on the soil surface and lightly pressing them to ensure they are in contact with the soil. The soil should be kept moist, and the seedlings should be placed in a shaded area until they can tolerate full sun exposure.
Cuttings
Propagation through cuttings involves taking stem cuttings from a mature plant and rooting them in a rooting hormone solution. The cuttings should be taken during the spring or winter by using a sharp, sterilized knife or pruning shears to take a 3-4 inch section of stem. The lower leaves of the cutting should be removed, and the cutting should be dipped in rooting hormone powder before being planted in a well-draining potting mix. The cutting should be kept moist and placed in a shaded area until new growth is observed.
With proper care and attention, Lobelia giberroa Hemsl. var. intermedia (Hauman) Robyns can be easily propagated through any of the above methods and will grow to become striking ornamental plants in any garden setting.
