Cultivation Methods
Manulea altissima L.f. subsp. altissima is a low-maintenance plant that can thrive in a wide range of growing conditions. This plant prefers well-draining soil that is rich in organic matter. It also prefers full sun to partial shade. When planting this plant in the ground, ensure that you dig the hole to a depth that is about twice the height of the root ball. Add organic matter to the soil, and backfill the hole, gently tamping down the soil as you go. Water the plant well after planting, and continue to keep the soil moist for the first two weeks.
Watering Needs
Manulea altissima L.f. subsp. altissima requires moderate watering. When watering, ensure that you do not overwater the plant, as this can lead to root rot. You should also avoid letting the soil dry out entirely, as this can cause the plant to wilt and die. Water the plant deeply once a week during the growing season and reduce the frequency during the winter months. A layer of mulch can help to retain moisture in the soil and reduce watering needs.
Fertilization
Fertilizing Manulea altissima L.f. subsp. altissima is not necessarily required but can help improve plant development and resilience. Use organic fertilizer in early spring, and repeat application every six weeks through early fall. Follow the manufacturer's instructions carefully, and avoid over-fertilization, as this can damage the plant.
Pruning
Manulea altissima L.f. subsp. altissima does not require frequent pruning. However, it benefits from occasional trimming to maintain a desirable shape and remove damaged or weak branches. Prune the plant in late winter or early spring before new growth begins. Prune the shrub's outermost branches, leaving a natural, rounded shape. Cut the stems back to just above a healthy bud or to maintain the desired height or shape. If necessary, staking the shrub supports can be a good alternative to pruning.
Propagation of Manuelia altissima L.f. subsp. altissima
Manuelia altissima L.f. subsp. altissima is propagated through both sexual and asexual methods. The plant can be grown from seed or vegetative cuttings.
Propagation from seeds
Manuelia altissima L.f. subsp. altissima produces small seeds that are sown during the spring or autumn in well-drained soil that is enriched with organic matter. The seeds are sown thinly, covered with a layer of soil, and watered well. Germination of seeds usually requires about 4 weeks, and it requires soil temperatures of 15-20°C.
Propagation from cuttings
Propagation of Manuelia altissima L.f. subsp. altissima using vegetative propagation can be carried out at any time of the year, depending on the climatic conditions. The shoots of the plant are selected, cut from the parent plant and treated with rooting hormone. The cuttings are then planted in a rooting medium that can include vermiculite, perlite, or a mixture of both. The cuttings require consistent moisture, and ideally, they need to be placed in a warm and shaded area. Rooting usually occurs within 2-3 weeks, and the cuttings can be planted out in the garden after they are well established.
