It is recommended to grow the plant in containers that are moved indoors during winter in cooler areas. The plant grows well from seed, which must first be soaked in warm water overnight before planting. Seedlings take about two weeks to emerge.
Watering Needs
For the Hibiscus cuanzensis Exell & Mendonça plant to grow well, it requires moderate watering. It is essential not to over-water the plant since this can cause root rot. Water the plant once a week during hot summer months, ensuring that the soil is moist but not waterlogged. During cooler months, water once every two weeks or when the soil is dry to the touch.
Fertilization
The Hibiscus cuanzensis Exell & Mendonça plant requires a balanced fertilizer containing equal amounts of nitrogen, phosphorus, and potassium. Apply the fertilizer during the growing season, starting in late spring and continuing until early autumn.

Pruning
The Hibiscus cuanzensis Exell & Mendonça plant requires pruning to keep it in shape and stimulate new growth. Prune the plant in late winter or early spring before new growth appears. Remove any weak or dead stems and cut back up to one-third of the plant's height. Pinch back the tips of new branches to encourage bushy growth and promote more flower production. Deadhead the plant regularly by removing spent flowers to promote more blooms.
Propagation of Hibiscus cuanzensis Exell & Mendonça
Hibiscus cuanzensis Exell & Mendonça is propagated through various methods including seeds, cuttings, layering, and grafting.
Propagation through seeds
The easiest and most common method of propagation for Hibiscus cuanzensis is through seeds. The seeds can be directly sown into the soil or in seed trays in a greenhouse. The seeds should be soaked in warm water for about 24 hours before planting to speed up the germination process. The ideal temperature for germination is around 25°C. The seeds will usually germinate within two to three weeks.
Propagation through cuttings
Cuttings from Hibiscus cuanzensis can be taken in the summer from new growth. The cuttings should be approximately 10-15 cm long with at least three to four leaves. Remove the lower leaves and dip the cut end in rooting hormone powder. The cuttings can be planted in a mix of sand and peat or directly in soil. Rooting should take place within two to three weeks.
Propagation through layering
Layering is another method of propagating Hibiscus cuanzensis which can produce good results. Choose a healthy stem and remove a strip of bark from the stem about 10-15 cm from the tip. Dust the wound with rooting hormone powder and wrap the area with moist sphagnum moss. Secure the moss with plastic wrap and wait for new roots to develop. Once there is enough rooting, cut the new plant from the mother plant.
Propagation through grafting
Grafting is a more advanced method of propagation that is typically used for more challenging cultivars. Cut a stem from the desired cultivar and bud it onto a rootstock. Once the bud has taken, the new plant can be grown out and planted.
