Everything it needs
9 essentials at a glance
Watering
Cissus quadrangularis prefers to be watered when the top inch of soil feels dry.
During the growing season (spring and summer), water every 1-2 weeks, providing enough water to saturate the soil but allowing excess to drain out. In fall and winter, reduce watering to once every 2-3 weeks. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause leaves to wilt and drop.
Light
This plant thrives in bright, indirect light but can tolerate partial shade.
Ideally, it should receive 4-6 hours of filtered sunlight daily. Direct sunlight can scorch the leaves, so placing it near a window with sheer curtains is beneficial. It can adapt to lower light conditions but may grow slower.
Soil
Cissus quadrangularis prefers a well-draining potting mix with a pH range of 6.0 to 7.0.
A mix of peat, perlite, and orchid bark works well to ensure good drainage. Avoid heavy soils that retain too much moisture, as this can lead to root rot.
Humidity
This plant enjoys moderate humidity levels around 40-60%.
To increase humidity, consider using a humidifier or placing a tray of water with pebbles beneath the pot. If the air is too dry, you may notice leaf tips browning or curling, indicating humidity stress.
Temperature
Cissus quadrangularis thrives in temperatures between 65-85°F (18-29°C).
It is not frost-tolerant and should be kept above 50°F (10°C). This plant can be grown outdoors in USDA hardiness zones 9-11, but it should be brought indoors during colder months.
Fertilizing
Use a balanced liquid fertilizer with an NPK ratio of 10-10-10 during the growing season, applying every 4-6 weeks.
In fall and winter, reduce fertilization as the plant enters dormancy. Signs of nutrient deficiency include yellowing leaves, stunted growth, and poor leaf development.
Pruning
Prune Cissus quadrangularis in early spring to encourage bushier growth and remove any dead or damaged stems.
Use clean, sharp pruning shears to make cuts just above a leaf node. Regularly pinching back the tips of the stems can also promote a fuller appearance.
Repotting
Repot Cissus quadrangularis every 1-2 years or when the roots outgrow the pot, indicated by roots growing out of the drainage holes.
Choose a pot 1-2 inches larger in diameter. To repot, gently remove the plant from its current pot, loosen any tightly bound roots, and place it in fresh potting mix, watering thoroughly afterward.
Propagation
Propagation can be done through stem cuttings or by division.
For stem cuttings, take a 4-6 inch cutting with at least two nodes, allow it to callous for a few hours, then plant it in moist potting mix. Keep the soil consistently moist until roots develop, which usually takes 2-4 weeks. Division can be done during repotting, ensuring each division has roots and stems.
When it's unhappy

Root rot
Why it happens
Over-watering and poor drainage.
How to fix it
Remove affected roots, repot in fresh soil, and adjust watering habits.
Care through the year
Spring
In spring, increase watering as the plant resumes growth and consider repotting if it has outgrown its current pot. Fertilize every 4-6 weeks to support new growth.
Summer
During summer, ensure the plant receives adequate light and water regularly, especially if temperatures rise. Monitor humidity levels to prevent stress.
Fall
In fall, gradually reduce watering as the plant enters dormancy. Fertilization can also be reduced to once every 6-8 weeks.
Winter
In winter, keep the plant in a warm location and water sparingly. Avoid fertilizing during this dormant period to prevent nutrient buildup.
