Propagation of Erica granulatifolia H.A.Baker
Erica granulatifolia H.A.Baker, commonly referred to as Granulated Heath, is a small perennial shrub that belongs to the Ericaceae family. The plant is native to the Western Cape in South Africa, where it grows in clay soil on hillsides and rocky slopes. Erica granulatifolia H.A.Baker produces small, fragrant, pink flowers that bloom from winter to early spring.
Seed Propagation
One of the easiest methods of propagating Erica granulatifolia H.A.Baker is through seeds. Seeds should be collected when the seed capsules have dried and cracked open, exposing the small brown seeds inside. These seeds can be stored in a cool dry place until they are required for propagation. Before sowing, the seeds must be soaked in water for 24 hours to soften the hard outer coating.
The seeds should be sown in shallow trays filled with a well-draining mix of equal parts of sand, loam, and peat moss. The seeds should be scattered on the surface of the soil and covered with a light layer of sand. The trays should be kept in bright light and kept moist but not waterlogged until the seeds germinate, which may take several weeks.
Cuttings Propagation
Another method used to propagate Erica granulatifolia H.A.Baker is through stem cuttings. The best time to take cuttings is in autumn when the plant is in the vegetative phase. Cuttings should be taken from the current season's growth and should be around 8cm long.
The bottom one-third of the cutting should be stripped of leaves, and the base should be dipped in rooting hormone before being inserted into a mixture of equal parts of sand and peat moss. The cutting should be kept in a warm, bright area and kept moist. Rooting should occur within six to eight weeks.
Division Propagation
Erica granulatifolia H.A.Baker can also be propagated through division in spring or autumn. The plant should be dug up and gently separated into smaller sections, ensuring that each section has several healthy roots and some new shoots.
The divided sections should be replanted in a well-draining soil mix of equal parts sand, peat moss, and loam. The plants should be kept well-watered and placed in a well-lit position, but out of direct sunlight until new growth appears.
Regardless of which propagation method is chosen, Erica granulatifolia H.A.Baker requires a moist but well-draining soil mix and a bright, sunny position to grow into healthy and mature plants.
