Light Requirements
Cissus leemansii Dewit prefers bright, but indirect sunlight. It can also survive in low light conditions, but it may result in weaker growth. A partially shaded spot would be ideal for this plant. Too much direct sunlight can cause sunscald, while too little light can result in leggy growth.
Temperature Range
Cissus leemansii Dewit can grow in a wide range of temperatures. Ideally, this plant prefers temperatures between 18°C to 24°C. However, it can also survive in temperatures as low as 15°C and as high as 30°C. The plant may become dormant during the winter months if the temperature drops too low.
Soil Requirements
The soil for Cissus leemansii Dewit should be well-draining and fertile. It should be rich in organic matter, and the soil pH must be slightly acidic to neutral, between 5.5 and 7.5. The plant requires good aeration within the soil, so it is recommended to add perlite or sand to improve drainage. Soil with too much clay can lead to the roots rotting.
Cultivation
Cissus leemansii Dewit is a tropical plant that thrives in warm temperatures and high humidity. It is advisable to grow it in a partially shaded area without direct sunlight. The plant can grow in any well-draining soil, but it prefers a mix of soil, peat moss, and perlite. The ideal pH level for the soil is between 6.0 and 7.0.
Watering
This plant prefers to be grown in moist soil, but be cautious not to over-water. It is recommended to allow the soil to dry partially before watering it again. During the winter, reduce the frequency of watering to prevent root rot. Ensure that the plant is not in standing water, as the roots may rot.
Fertilization
Fertilize the plant every two weeks during the growing season. Feed it with a 10-10-10 liquid fertilizer or an organic, well-balanced fertilizer. Do not fertilize during winter when the plant is dormant.
Pruning
Cissus leemansii Dewit grows quickly and needs to be pruned regularly to prevent it from getting too leggy. Prune the plant in the spring and summer by removing the excess growth. Pinch the stem tips to encourage the plant's bushy growth and encourage the production of new leaves. The plant tends to produce tendrils that it uses to climb; it is advisable to trim these tendrils to control the plant's growth.
Propagation of Cissus leemansii Dewit
Cissus leemansii Dewit, also known as the African grape ivy, is a fast-growing vine that can reach up to 12 feet in length. Propagation of this plant is relatively straightforward, and there are several methods to choose from.
Propagation by stem cuttings
One of the most common ways to propagate Cissus leemansii Dewit is through stem cuttings. Here are the steps:
- Choose a healthy stem and cut a 4- to 6-inch section.
- Remove the bottom leaves, leaving only two or three at the top.
- Dip the cut end in rooting hormone.
- Plant the cutting in a well-draining soil mixture.
- Water the cutting and keep the soil moist, but not saturated.
- Place the cutting in a bright, warm area, but out of direct sunlight.
- After about 2 to 4 weeks, check for root development by gently tugging on the stem. If there is resistance, roots have grown.
- Once roots have formed, transfer the plant to a larger container or outdoor space.
Propagation by air layering
Air layering is another effective propagation method for Cissus leemansii Dewit. Here's how to do it:
- Select a healthy stem and make a 1-inch notch on the stem, halfway through the diameter of the stem.
- Apply rooting hormone to the area around the notch.
- Wrap a moist ball of sphagnum moss around the cut, making sure it is in contact with the rooting hormone. Cover the moss with plastic wrap and secure it with twist ties.
- Check the moss every week, making sure it remains moist. Roots should begin to form within 4 to 6 weeks.
- Once roots have grown, cut the stem below the moss and pot the new plant in well-draining soil.
Whether you choose stem cuttings or air layering, propagation of Cissus leemansii Dewit is a rewarding process that will provide you with beautiful and healthy new plants to enjoy.
Disease and Pest Management for Cissus leemansii Dewit Plant

Mealybugs are tiny, soft-bodied insects that usually appear as white cottony masses on the plant. Spider mites, on the other hand, are small, eight-legged pests that cause yellow or brown stippling on the leaves. Scale insects are small, oval-shaped pests that suck the sap from the plant, causing yellowing and wilting. To manage these pests, you can use insecticidal soaps or horticultural oils. You can also manually remove the pests by wiping the affected areas with a damp cloth.
Preventive Measures
Preventing diseases and pests from affecting Cissus leemansii can be less costly and time-consuming than treating them.
