Propagation of Gilbertiodendron limba
Gilbertiodendron limba can be propagated by two methods: seed propagation and vegetative propagation.
Seed propagation
The seeds of Gilbertiodendron limba can be collected from the wild during the fruiting season. The fruit is a long pod that contains several seeds. The pods can be collected and left to dry in the sun for a few days. Once the pods are dry, they can be opened to collect the seeds.
The collected seeds are then soaked in water for a day to soften the coat. This will aid germination. The seeds can then be sown directly into pots or nursery beds filled with a mixture of fertile soil and sand.
The pots or beds should be kept moist, but not waterlogged. Germination can take up to three weeks. Once the seedlings are about a foot tall, they can be transplanted to permanent locations.
Vegetative propagation
Vegetative propagation of Gilbertiodendron limba involves taking cuttings from the parent plant, rooting these cuttings, and planting them to form new plants. This method is used to propagate selected strains that have desirable characteristics that are lost through sexual propagation.
The cuttings should be 6-8 inches in length and taken from mature, healthy trees. The cuttings should have at least two leaves and be from the previous year's wood. The cuttings should be treated with rooting hormone to increase the chances of rooting.
The cuttings should be planted in a rooting medium consisting of a mixture of sand and peat moss. The cuttings should be kept moist, but not waterlogged. Roots should start to form within a few weeks. The rooted cuttings can then be transplanted into pots or nursery beds and grown to maturity.
