Propagation methods of Cyrtandra platyphylla Gray var. robusta Rock
Propagating Cyrtandra platyphylla Gray var. robusta Rock is quite easy as the plant has the ability to grow quickly from various types of propagation methods. Some of the common propagation methods for this plant are:
Propagation through Seeds
Cyrtandra platyphylla Gray var. robusta Rock can be propagated through seeds. Seeds should be collected when the fruit ripens. The fruit then should be placed in a container and broken down into parts by applying pressure. The container should be filled up with water and gently stirred. Finally, the mixture should be left to settle for some days. The top layer of the mixture should be removed with a spoon, and the bottom-layered water containing the seeds should be poured off into another container. The seeds should then be sown shallowly in a seedling tray containing a mixture of peat moss and perlite or sand. The seedling tray should be placed in a shady area and kept moist until germination occurs.
Propagation through Stem Cuttings
Cyrtandra platyphylla Gray var. robusta Rock can be propagated easily through stem cuttings. Select healthy cuttings of about 5 to 6 inches in length with at least three leaves. The lower one inch of the stem then should be removed and the cutting should be dipped in rooting hormone. The stemcuttings should then be planted in a container filled with a mixture of peat moss and perlite or sand. The container should be placed in a shady area and kept moist until roots develop.
Propagation through Division
Cyrtandra platyphylla Gray var. robusta Rock can be propagated through division because it has a clumping habit. To propagate through division, the clumps should be carefully removed from the soil, and the clumps should then be divided into several smaller clumps by hand. The small clumps should then be replanted into pots filled with a mixture of peat moss and perlite or sand. The pots should be placed in a shady area and kept moist until the plants are well-established.
