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.
Growth habit: Vigorous semi-succulent climbing or trailing vine that grips supports with tendrils; can be trained up a trellis or left to cascade.
What fertiliser cissus rotundifolia actually wants — and why
Cissus rotundifolia is an easy, light foliage feeder — a half-strength balanced liquid feed through the growing months keeps it green without forcing weak, sappy growth.
A balanced general houseplant feed (roughly even N-P-K) is exactly right — it is grown for foliage, so steady, moderate nitrogen for healthy leaves is the goal, not a bloom or root formula.
For the language behind the three numbers on the bottle — what nitrogen, phosphorus and potassium each do — see the NPK ratio explained entry. The short version for cissus rotundifolia: match the feed to the job the plant is doing right now, not to a generic “plant food” on the shelf.
How often to feed cissus rotundifolia, and which months
Feeding only earns its keep while the plant is in active growth and can use the nutrients — pour feed into a dormant or low-light plant and it simply builds up as root-burning salt. For cissus rotundifolia:
Feed monthly through spring and summer with a balanced liquid houseplant feed at half strength. This is a fast grower when happy, so steady growing-season feeding supports its vigour. Stop feeding in autumn and winter. Treat that as monthly between spring through early autumn (roughly March to September); ease off in autumn and stop entirely in the low light of winter.
The dormant-season rule matters more than the exact interval: skip feeding entirely when cissus rotundifolia is resting. For the wider context on indoor feeding rhythms across the seasons, the houseplant fertiliser schedule walks through the year month by month.
What strength to mix for cissus rotundifolia
Half strength is the safe default for cissus rotundifolia — houseplant feeds are formulated strong, and the diluted dose is gentler on the roots while still ample for foliage.
Feeding always goes onto already-damp soil, never dry roots — water cissus rotundifolia first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the cissus rotundifolia watering schedule.
Signs you are over-feeding cissus rotundifolia
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for cissus rotundifolia:
- Brown, crispy leaf tips and edges with no sign of underwatering.
- A white, crusty salt deposit on the soil surface or pot rim.
- Weak, pale, stretched new growth that flops.
- Lower leaves yellow and drop while the soil is correctly watered.
Signs you are under-feeding cissus rotundifolia
- Uniformly pale or yellow-green leaves, oldest first.
- Noticeably small new leaves and stalled growth in good light and season.
- A generally tired, lacklustre look despite correct watering and light.
If the symptoms point at watering, light or roots rather than nutrition, the full cissus rotundifolia care brief covers soil, humidity and the common problems for this species.
Flushing and leaching the salts
Flush the pot of cissus rotundifolia with plain water until it runs freely from the base every couple of months in the feeding season — it washes out the fertiliser salts that cause brown tips.
Organic vs synthetic feeds for cissus rotundifolia
Organic options
A diluted seaweed or worm-casting feed, or fish emulsion if you can tolerate the smell indoors. UK: Westland or Baby Bio Organic, dilute seaweed; US: Espoma Indoor! or Neptune's Harvest fish & seaweed. Slow, gentle and hard to overdo.
Synthetic / liquid feeds
A general-purpose houseplant liquid at half strength — UK: Baby Bio, Westland Houseplant Feed or Phostrogen; US: Miracle-Gro Indoor Plant Food or Schultz. Convenient and fast-acting; the only risk is overdoing it.
Brand names are examples, not endorsements, and UK and US ranges differ — check the label’s own NPK and dilution rate, since formulations change.

What does over-feeding cissus rotundifolia look like?
Brown, crispy leaf tips and edges with no sign of underwatering. A white, crusty salt deposit on the soil surface or pot rim. Weak, pale, stretched new growth that flops. Lower leaves yellow and drop while the soil is correctly watered. Feeding cissus rotundifolia year-round on a fixed schedule, including dark winter months, is the most common mistake — it cannot use the nutrients in low light and the surplus simply burns the roots and crusts the soil.
Should I flush the soil of cissus rotundifolia?
Flush the pot of cissus rotundifolia with plain water until it runs freely from the base every couple of months in the feeding season — it washes out the fertiliser salts that cause brown tips.
