More about bower vine
About Bower Vine
Pandorea jasminoides · also called Bower Vine, Bower of Beauty · tropical
An elegant, fast-growing evergreen twiner from eastern Australia bearing clusters of funnel-shaped white to pale pink flowers with a deep pink throat from spring through autumn. Ideal for pergolas, trellises, and fences in warm climates. Responds well to light pruning to maintain shape and promote repeat blooming.
Growth habit: Evergreen twining climber; stems twine around support
Watch for — Leaf drop in cool winters: May become semi-deciduous or lose leaves when temperatures drop below 10°C (50°F). This is normal dormancy behaviour; reduce watering and avoid fertilising until spring warmth returns.
What fertiliser bower vine actually wants — and why
Bower Vine 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 bower vine: 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 bower vine, 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 bower vine:
Feed with a balanced slow-release fertiliser (NPK 10-10-10) in early spring, then switch to a high-potassium liquid feed every 2–3 weeks through summer to promote flowering. Reduce feeding in autumn and stop in winter. Treat that as sparingly through the growing season 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 bower vine 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 bower vine
Half strength is the safe default for bower vine — 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 bower vine first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the bower vine watering schedule.
Signs you are over-feeding bower vine
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for bower vine:
- 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 bower vine
- 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 bower vine care brief covers soil, humidity and the common problems for this species.
Flushing and leaching the salts
Flush the pot of bower vine 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 bower vine
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 bower vine 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 bower vine 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 bower vine?
Flush the pot of bower vine 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.
