Propagation of Lobelia gaudichaudii A. DC. ssp. koolauensis (Hosaka & Fosberg) Lammers
The Lobelia gaudichaudii A. DC. ssp. koolauensis (Hosaka & Fosberg) Lammers is a beautiful plant species native to Hawaii. It is a small herb with attractive blue flowers and is generally found in wet forests. The plant is suitable for growth in gardens and is known for its low-maintenance requirements. The plant can be propagated using seeds, cuttings, and divisions.
Propagation by Seeds
Propagation through seeds is the most common method of propagating Lobelia gaudichaudii A. DC. ssp. koolauensis (Hosaka & Fosberg) Lammers. Seeds are readily available from mature plants and are easy to germinate. Sow the seeds in a seed tray filled with moist potting soil and cover lightly with soil. Keep the soil moist and at a temperature range of 18-20°C. The seeds usually germinate within 1-2 weeks. When the seedlings are large enough to handle, transplant them to individual pots and grow them until they are large enough to transplant to a garden.
Propagation by Cuttings
Propagation through cuttings is one of the easiest and quickest methods to get new plants. Cuttings should be taken from the youngest stems with no flowers. The cuttings should be approximately 10-15cm long. Dip the cut end of the stem in rooting hormone and insert it in moist, well-draining soil or sand. Keep the soil moist and at a temperature range of 18-20°C. Roots should begin to develop in 3-4 weeks. When the cuttings have established roots, transplant them to individual pots, and grow them until they are large enough to transplant outdoors.
Propagation by Division
Propagation through division is another viable method for Lobelia gaudichaudii A. DC. ssp. koolauensis (Hosaka & Fosberg) Lammers. Divide the plant in the spring when it has become too large for the pot. Carefully remove the plant from the pot and separate it into new plants by gently pulling the roots apart. Make sure that each section has healthy roots. Plant each new plant into a pot, water well, and grow until large enough to transplant outdoors.
