Oak Leaf Ivy
Oak Leaf Ivy, also known as Cissus rhombifolia, is a tropical vine creeper with glossy foliage. It has beautiful leaves that are shaped like broad oak leaves which can grow to 5 inches. It grows best in bright, indirect sunlight and prefers a humid environment. It grows rapidly in ideal conditions and is known for being quite tough. On average, this tropical houseplant will grow to be three to six feet tall and is usually potted in hanging baskets to show off its trailing vine stems. Feeding and pruning may be necessary, but regular watering is key for growth and survival.
Oak Leaf Ivy should be watered regularly with lukewarm water, ensuring that the soil is evenly moist but not soggy. However, it cannot be allowed to dry out completely or else it will become vulnerable to pests and the leaves will start to brown and curl. Frequent misting can help the soil remain moist since this is a tropical houseplant and its humidity preferences.
Oak Leaf Ivy prefers bright, indirect light to full, direct sun. Too much direct sun can cause the tips of the leaves to burn, therefore partial shade is ideal for this houseplant. However, if there is not enough light, the leaves will become yellow and growth will be stunted.
Oak Leaf Ivy does best in a warm room temperature of 68-75°F (20-24°C). The plant can tolerate temperatures lower than its ideal, but it should not drop whinn 65°F(18°C). A sudden change in temperature can lead to the plant becoming limp and developing brown tips.
This tropical houseplant prefers a high level of humidity, ideally above 60%. Keeping a humidity tray or humidifier nearby can help maintain a higher humidity level. Regular misting can also increase the humidity around the leaves.
Oak Leaf Ivy is best planted in a nutrient-rich, well-draining soil mix. Choose a soil with a neutral or slightly acidic pH (6.0-6.5). A mixture of vermiculite, shredded bark, and peat moss with some rich compost may be used for light, airy, well-draining soil.
Oak Leaf Ivy should be fertilized in the summertime once every two weeks with a low-nitrogen, balanced houseplant fertilizer. When temperatures are cooler outside, it should be fed less or not at all. Besides fertilizing, compost may be applied around the soil surface to give the plant some extra nutrients.
Spider mites, aphids, and mealybugs may attack Oak Leaf Ivy if there isn’t enough humidity. Once discovered, it is important to take measures to contain the infestation and eradicate it. Pruning and removing infected leaves, as well as regularly misting, can help. Applying neem oil may also help keep the pests away, particularly if used alongside the other measures mentioned.
Oak Leaf Ivy should be repotted every 2-3 years or when the pot has become crowded. When repotting, it is best to use a slightly larger pot and a lightweight potting mix with some perlite or bark for drainage. A well-draining potting mix helps to prevent waterlogging and root rot.
Pruning Oak Leaf Ivy at least once a year can help to encourage bushiness and direct lateral growth. To encourage bushy growth, prune back a little of each existing stem right after the new growth starts, and new shoots can be pinched back to 3-4 pairs of leaves. Additionally, regular pruning of dead or diseased leaves can help keep the plant healthy as well as visually appealing.
Mulching around the base of the plant may be beneficial for Oak Leaf Ivy. For example, shredded bark, wood chips, or even moist leaves may be used as mulch. This helps to keep the soil moist and the shallow roots cool, as well as providing some extra structural support for the trailing stems.
Oak Leaf Ivy can be propagated by both stem cuttings and leaves. For stem cuttings, cut a stem a few inches long, remove the lower leaves, dry the ends in sand or on a paper towel, then dip in some rooting hormone. Leaf cuttings can be taken by removing a few leaves with petioles, drying the ends in sand, then dip in rooting hormone. Both methods should be repotted when the roots have grown long enough in root-inducing pots and soil and some light misting is recommended until it starts to root and show signs of growth.
As a vigorous climber, this plant may need extra support such as a trellis, stake, or even a combination of both for the longer vines. Training the vines on a structure or bamboo canes can help to control the spread of the stems as well as to encourage bushy growth.
Oak Leaf Ivy may benefit from a rest period during the wintertime. During its rest period, the plant should only be watered every 2-3 weeks. The light should be kept at moderate levels and the temperature should remain between 40-65°F (5-18°C). This will help to encourage the plant to produce more shoots in the spring.
Oak Leaf Ivy is not toxic to pets, and thus is considered pet-friendly.
