Bleeding Heart Vine
The Bleeding Heart Vine (Clerodendrum thomsoniae) is a stunning and exotic plant of the Clerodendrum family. It is native to tropical West Africa, and is commonly seen in tropical climates throughout the world. The heart-shaped leaves are deep and vivid green, and are accented by delicate, bright pink petals that appear in late spring and early summer. The flowering can last up to three months in ideal conditions, and the vine can reach up to 10 feet in length. The Bleeding Heart Vine is a great choice for those who love exotic plants and want to bring dramatic color to their home.
Watering your Bleeding Heart Vine is relatively easy, but proper technique is essential to its health. The plant likes moist soil that is not allowed to dry out. Water the plant regularly, making sure the soil has been evenly moistened. Do not waterlog the plant, as that can cause root rot. Check the top of the soil about once a week, if the top 2-3 inches are dry, it is time to water the plant again. Do not water the plant until you see the leaves starting to droop, that could be a sign of over-watering and could harm the plant.
The Bleeding Heart Vine prefers bright, indirect sunlight. It should not get more than a few hours of direct sun a day. This helps protect the vibrant colors of the petals and the rich green of the foliage from fading. If the vine gets too much sun, it can cause its leaves to brown up and shrivel. On the other hand, if it doesn’t get enough sun, the plant will become pale and leggy, unable to support the growth of the flowers. To ensure optimal growth, try to find a spot with bright, filtered light for your Bleeding Heart Vine.
The ideal temperature range for the Bleeding Heart Vine is between 60-85°F (16-29°C). The plant can tolerate slight temperature drops as low as 40-45°F (4-7°C) but prolonged cold temperatures can damage the foliage and cause the flowers to become less vibrant and wilt faster. It is best to keep the vine indoors during cool winters so it can be protected from frost and cold temperatures.
The Bleeding Heart Vine prefers high humidity levels, around 50-80%. In drier climates, or during the winter months when the climate is at its driest, you may need to supplement the humidity with misting or a room humidifier. It can also be beneficial to place the plant near other household plants, as that creates an environment that can help more easily maintain the desirable humidity levels.
The Bleeding Heart Vine prefers a soil mix that is well-draining yet still able to retain moisture. A potting mix consisting of 1 part peat moss, 1 part perlite, and 1 part compost. Add organic matter such as aged manure, compost or shredded bark to increase the nutrient and moisture content of the soil.
Fertilizing the Bleeding Heart Vine is a great way to encourage healthy growth and vibrant flowers. Fertilize the plant every 3 weeks during the spring and summer, using a balanced fertilizer such as a 10-10-10. Be sure to follow the directions on the package for the correct application rate. In the winter months, the plant should be given a rest from fertilizing.
Bleeding Heart Vines are prone to attack by several different pests, including aphids, mealybugs, spider mites, thrips, and whiteflies. Aphids can be controlled by spraying the plant every few days with a soapy water mixture. For heavy infestations, you may need to use an insecticidal soap. Mealybugs can be treated with the same soap mixture, or with neem oil. Thrips and spider mites can be treated with the same horticultural soaps as the other pests. Whiteflies can also be treated with the soap or neem oil, or by trapping them with yellow sticky traps.
Repotting should be done every spring when the plant first starts to grow in the season. You should choose a pot that is 1-2 inches larger than the current one, filled with a well-draining potting mix. Carefully remove the plant from its current pot, checking the roots for signs of disease or rot. Trim any dead or diseased roots and repot the plant into its new pot. Firm the soil around the base and water it until the excess water is drained out of the bottom.
The Bleeding Heart Vine needs regular pruning and shaping to maintain the desired form and encourage flowering. Pruning should be done periodically throughout the growing season to help keep the plant manageable. Pruning should be focused on removing old woody stems, dead branches, and weak shoots—this will help encourage new growth and keep the plant looking bright and healthy.
Mulching around the Bleeding Heart Vine is a great way to conserve moisture and discourage weed growth. A 2-3 inch layer of mulch around the base of the plant will do the trick. Use a material that decomposes slowly, such as wood chips, pine needles or cocoa husks. It is also important to make sure the mulch doesn’t come in contact with the plant to prevent it from getting waterlogged and causing fungal diseases.
Propagation of the Bleeding Heart Vine can be done either through seeds or cuttings. Seeds should be started in early spring in a well-draining soil mix. Keep the soil lightly moist until germination. Cuttings should be taken in early summer and should have at least 3 sets of leaves. Dip the lower end of the cutting in rooting hormone and plant in a moist, well-draining potting mix. Place the cutting in bright indirect light and keep the soil lightly moist. Keep the potting mix draft free. Rooting should occur in 3-4 weeks.
The Bleeding Heart Vine will need some type of support to ensure that it doesn't break from its own weight. You can use canes or stakes for support, or you can create a trellis or frame for it to climb up. Having a support structure will help keep the plant upright and prevent breakage.
The Bleeding Heart Vine does not need a dormant period during the winter months, but it may benefit from a slight rest period during the summer months. From the middle of summer until fall, the plant should be allowed to rest, with less frequent waterings. This will help the plant conserve energy and build up reserves for the next season’s growth.
The Bleeding Heart Vine contains compounds that are toxic to animals, so it is best to keep it out of reach of pets and children. If ingested, it can lead to irritation of the mouth, throat, and gastrointestinal system. Contact with the sap of the plant can also cause skin irritation.
