Grow and Care Tips

Sun Requirement

The Rangoon creeper is a tropical plant, which makes it love to be exposed under full sun. Although, it also thrives in areas under partial shade. Also, make sure that this plant gets six uninterrupted hours of sun exposure to help bear more blooms.

Water Requirement

As a versatile vine, it only needs moderate amounts of water. However, the frequency of watering is altered when the climate changes. For example, watering more frequently is advised during hot summer days. On the other hand, less frequent watering should be done during cold winters.

Temperature and Humidity

The Rangoon creeper tolerates high temperatures but does not do well in colder temperatures.

Soil Requirement

In terms of the planting medium, the vine flourishes with well-drained sand, clay, or loam soils. Also, the soil pH must range from acidic to neutral. It is intolerant to soil salts, which is why the application of fertilizers must be thought out.

In terms of the planting distance, it is imperative to let this vine have room for growth. A 4 to 5 feet gap from other plants is the minimum planting distance.

Fertilizer Requirement

As long as the soil is rich in organic matter, the application of fertilizer is not needed. Also, avoid putting nitrogen-rich fertilizers during the plant’s flowering stage. Nitrogen fertilizers will promote more foliage production rather than flower formation.

A bi-annual application of complete fertilizer may be done. Remember to follow the right amount of fertilizer, as indicated in the packaging, to avoid nutrient toxicity and salt build-up.

Maintenance Activities

As a deciduous plant, the Rangoon creeper sheds its leaves annually. During its shedding period, cleaning the fallen leaves around the area is one of the necessary maintenance activities.

This activity is vital because it will prevent debris build-up on the soil and make the plant less susceptible to soil-borne diseases and other pathogens. Another activity that helps in the prevention of pests and diseases is pruning.

Since the Rangoon creeper is a fast grower, pruning should be done whenever necessary. Removal of dead plant parts and rejuvenative pruning extend the plant’s life and replenish its vigor and appearance.

Propagation

There are two ways to propagate the Rangoon vine, by seed or stem cuttings. For both planting materials, it is a must to have a seedbed or plant pots with well-drained and loose soil placed in a warm area.

Application of rooting hormones, such as auxin, will help the planting materials form roots faster. Also, misting is the best way to water because it will provide a uniform amount for all the seedlings and cuttings.

Avoid exposure to full sun while the plant is still developing its root system. However, they may be transplanted to areas under the full sun once the seedlings are sturdy enough. These young vines are in the perfect stage to train.

Training is often done by providing a supporting structure, like a trellis or a stake, and letting the vine latch on to it. Also, stems that run wild and against the desired form are cut.

Function In The Landscape

The Rangoon creeper may serve as a privacy screen, green wall, shade, and specimen plant in a garden. Its broad and dense leaves make it a good screen and shade, which is done by letting the vine crawl all over fences, arbors, trellises, and pergolas. It is a beautiful overhead shade during its bloom season.

Also, its rough texture is a beautiful addition to a green wall and could be grown among soft-textured plants with smaller leaves. It is a pleasing backdrop with only its foliage but even more so when its flowers start to show.

Lastly, planting it as a specimen plant is also practiced in some gardens. Its fragrance and appearance make heads turn. To serve this function, some gardeners cultivate them in containers. Also, they provide a guiding structure for the vine. In doing so, it has to be pruned more frequently.

Potential Harm

Although this vine is not reported to be invasive, it still has the potential to be an aggressive weed in a landscape. Its fast growth allows it to easily take over an area and destroy other existing vegetation. This potential threat is why it is important to keep this plant pruned regularly and planted with ample space.
