Pruning
Pruning Tarenna gilletii is a crucial aspect of its care. Pruning should be done in the early spring season before the plant breaks bud. This helps in shaping the plant, removing dead or damaged branches and encouraging new growth. The plant is known to produce suckers that should be pruned regularly. This promotes a denser growth habit and prevents the plant from looking too leggy.
Propagation of Tarenna gilletii
Tarenna gilletii can be propagated through several methods which include:
Seed propagation
Seeds of Tarenna gilletii can be collected from mature fruits of the plant. The collected seeds should be cleaned and soaked in water for a few hours. They should then be sown in a potting mixture made of equal parts of sand, loam, and leaf mold. The potting mixture should be kept moist throughout the germination period. Germination of seeds may take up to 3 months.
Cuttings propagation
Softwood cuttings of Tarenna gilletii can be taken from the tips of the plant during the growing season. The cuttings should be about 7-10 cm long and should be dipped in a rooting hormone. The cuttings can then be planted in a potting mixture made of equal parts of sand and peat moss. The soil should be kept moist and the cuttings should be placed in a shaded area until they have rooted, which may take up to 3-4 weeks.
Division propagation
Tarenna gilletii can also be propagated through division. The plant can be divided during the dormant season by separating the roots and shoots. Each divided portion should contain healthy roots and shoots. The divided portions can then be planted in a potting mixture made of equal parts of sand, loam, and leaf mold. The soil should be kept moist and the plant should be placed in a shaded area until it has established.
Propagation of Tarenna gilletii can be a rewarding experience and can help preserve this plant species for the future.
