About Cissus rotundifolia

Cissus rotundifolia · also called Arabian Wax Cissus, Perennial Grape · houseplant

Cissus rotundifolia is a vigorous semi-succulent climbing vine from Arabia and East Africa, with thick, waxy, rounded blue-green leaves and curling tendrils. Tougher and more drought-tolerant than the fern-leaf grape ivies, it stores water in its fleshy leaves and stems and shrugs off heat and bright light. Give it a trellis or let it cascade from a hanging pot.

Mature size: Climbs or trails 1.5-3 m (5-10 ft) indoors; waxy rounded leaves are about 3-6 cm across.

Watch for — Yellowing leaves from overwatering: Soggy soil makes the succulent leaves yellow and drop. Let the top of the soil dry between waterings and ensure the pot drains freely.

How to tell cissus rotundifolia needs repotting

Repotting on a calendar is less reliable than reading the plant. For cissus rotundifolia, watch for these signs:

Roots growing out of the drainage holes, or the rootball lifting the plant proud of the rim.
Soil that has shrunk away from the pot sides and no longer holds water.
The pot is unstable because the plant has grown top-heavy.
Old, compacted, broken-down mix that stays wet too long — for a succulent that is a rot risk, so refresh it even if the pot size is fine.

How often to repot cissus rotundifolia

Every 2–3 years, into bone-dry mix. Cissus rotundifolia's growth habit — vigorous semi-succulent climbing or trailing vine that grips supports with tendrils; can be trained up a trellis or left to cascade. — sets the pace. Cissus rotundifolia is a vigorous semi-succulent climbing vine from Arabia and East Africa, with thick, waxy, rounded blue-green leaves and curling tendrils. Tougher and more drought-tolerant than the fern-leaf grape ivies, it stores water in its fleshy leaves and stems and shrugs off heat and bright light. Give it a trellis or let it cascade from a hanging pot.

What size pot to step cissus rotundifolia up to

Use a pot only one size up — or even the same pot with fresh gritty mix if the roots have room. Cissus rotundifolia stores water and rots in a large pot of slow-drying soil. A tight terracotta pot that dries fast is far safer than a generous plastic one. Never up-pot a succulent by several sizes.

The best time of year to repot cissus rotundifolia

Spring or summer, while cissus rotundifolia is in active growth and warm, is best — roots recover fastest then, and the plant is not sitting in cool damp soil. Avoid repotting a succulent in winter dormancy.

Step-by-step: repotting cissus rotundifolia

Repot dry. Do not water cissus rotundifolia for several days first. Working with dry roots and dry mix dramatically lowers the rot risk for a succulent.
Pick a snug, fast-draining pot. Choose terracotta one size up at most, with a drainage hole. Have gritty free-draining, gritty potting mix ready.
Tip it out and clean the roots. Slide the plant out, crumble off the old soil, and trim any black, mushy or dead roots with clean snips.
Pot into dry mix. Set cissus rotundifolia at its original depth in dry gritty mix, firming gently. Do not bury the stem deeper than it was.
Wait a week before watering. Leave it completely dry and out of harsh sun for about 7 days so any damaged roots callus. Only then water lightly.

Aftercare

Keep cissus rotundifolia completely dry and out of fierce sun for about a week so any nicked roots callus before they meet moisture; watering a freshly repotted succulent is the classic way to rot it. Then resume the normal lean, dry rhythm. Do not fertilise for about 3 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for cissus rotundifolia

Cissus rotundifolia wants free-draining, gritty potting mix. Use a good houseplant compost amended with perlite or coarse sand, or a cactus mix with some added organic matter. Sharp drainage protects the fleshy roots; always use a pot with drainage holes. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting cissus rotundifolia — frequently asked questions

How often should you repot cissus rotundifolia?

Every 2–3 years, into bone-dry mix for cissus rotundifolia. Repot cissus rotundifolia every 2–3 years into a snug pot of free-draining, gritty potting mix, ideally in spring or summer. Let it sit in dry soil and do not water for about a week afterwards so any nicked roots can callus. Over-potting and watering straight away is what rots succulents.

What size pot does cissus rotundifolia need?

When is the best time of year to repot cissus rotundifolia?

Should you water cissus rotundifolia after repotting?

No — not straight away. Repot cissus rotundifolia into dry mix and wait about a week before the first watering so any damaged roots callus over. Watering a freshly repotted succulent is the single most common way to rot one.

Should you fertilise cissus rotundifolia after repotting?

Not immediately. Wait about 3 weeks after repotting cissus rotundifolia. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
