Dombeya

Dombeyas need regular waterings throughout the growing season, but be sure to not over water or saturate the soil. Allow the top several inches of soil to dry out between waterings. During the winter, reduce the frequency of watering significantly, as the plant’s growth rate slows significantly during this season. Increase watering during periods of extreme heat and drought.

Most Dombeya species require at least partial light, but some varieties can tolerate full sun, so it is important to know the specific requirements of the specific species when selecting a plant. too much sun will cause the leaves to be scorched and the blooms to fade quickly. Areas that receive direct morning sun for several hours, followed by shade in the afternoon, are ideal for most species. Too little light can also be an issue, as it will cause the plant to become spindly and devoid of blossoms.

As tropical plants, Dombeyas prefer to remain in temperatures that are consistently between 60°F (16°C) and 85°F (29.4°C). They are able to survive temperatures outside of this range, but they will not thrive and may suffer from stress. The habit of most Dombeya plants makes them ideal for indoor growing in cooler climates.

As tropical plants, Dombeyas require higher levels of humidity to thrive. Ensure the air surrounding the plant is humidified or mist the foliage at regular intervals during the growing season. Adding a layer of peat or sphagnum moss over the soil will also help to retain moisture in the root zone.

Dombeyas require well-drained, slightly acidic soil (pH 6.5-7.0) in order to thrive. If planting them in the ground, be sure to mix compost with the soil for extra aeration and nutrients. It is also recommended to mix in some fertilizer when planting or repotting the plant, to provide it with the necessary nutrients for healthy growth.

Dombeyas benefit from regular fertilization during the growing season. Always use a balanced, slow-release liquid plant food; avoid using too much nitrogen if actively blooming. Apply a fertilizer once every two weeks, following the instructions on the package for rate and quantity. Reduce the application to once a month during the winter months.

When grown indoors, Dombeyas are rarely affected by any pests, though mealybugs and scale insects may occasionally appear. If aphids are spotted, a soft cloth can be used to wipe them away, but if the infestation is severe, an insecticidal soap or neem oil spray can be used to effectively treat the issue. Outdoor plants are more prone to pests and disease, but most issues can be prevented by providing the plant with adequate air circulation and avoiding waterlogged soil. If brown spots appear on the foliage, this may be indicative of a fungal infection. Reduce watering and treat with a fungicidal spray.

When the plant reaches the edges of the pot and looks rootbound, it is time to repot it. Dombeyas should be repotted every 2-3 years, preferably in the spring or summer. Choose a pot that is slightly larger than the current pot, and use fresh, fast-draining potting soil to ensure good aeration and drainage for the roots. Be sure not to pot the plant too deeply, as this can cause rot and other issues.

Dombeyas need minimal pruning outside of the occasional deadheading to keep the plant tidy and encourage more blooms. If they are grown for their foliage as well, then pruning for shape can be done occasionally. Ensure they are pruned at the correct time of year - during the dormant period or after the flowering period - so as not to adversely affect the blooms.

Mulching around the base of the Dombeya with organic materials such as shredded bark, leaves, or pine needles can help to keep the soil moist and cool and prevent weeds from competing for nutrients and water. Avoid using any materials containing plastics.

Depending on the species, Dombeyas may be propagated either by seed or cuttings. If propagating by seed, the seeds should be sown in a flat or container filled with a well-draining planting medium. Keep the soil consistently damp and the container in a warm, humid environment, such as a propagator, until the seedlings have sprouted. For cuttings, use a sharp and clean pair of scissors or pruners to take 6-8 inch long cuttings from the tips of new shoots. Place the cuttings in a container of water or moist soil and keep it moist and in a warm, humid environment until the cuttings have rooted.

Since most Dombeya species are tall and have a weeping habit, they may need a little extra support to help keep them upright. A stake or bamboo pole can be inserted into the potting soil and tied to the trunk for extra stability.

Dombeyas grow best when they are given a period of rest during the winter months. During this time, reduce the watering significantly and avoid adding any additional fertilizers, as this can disrupt the plant’s natural growth cycles. When spring returns, resume regular watering and fertilizing.

No, Dombeya is not known to be toxic to pets.
