About Clematis tangutica
Clematis tangutica · also called golden clematis, Tangut clematis · flowering
A hardy species clematis from Central Asia, bearing nodding, lantern-shaped yellow flowers with thick lemon-peel petals from midsummer into autumn, followed by ornamental silky silvery seedheads. A Group 3 climber pruned hard in late winter, it is vigorous, drought-tolerant once established, and superb scrambling over fences, banks and through shrubs.
Growth habit: Vigorous deciduous twining climber clinging by leaf stalks; scrambles over fences, walls, banks and large shrubs, and can self-seed freely in suitable conditions.
What fertiliser clematis tangutica actually wants — and why
Clematis tangutica flowers best on poor soil — feed it and you get a lush leafy plant with very few blooms, the exact opposite of what you want.
Little or nothing. Rich, especially nitrogen-rich, soil pushes foliage at the expense of flowers in this plant — lean ground is the technique, not a deficiency.
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 clematis tangutica: 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 clematis tangutica, 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 clematis tangutica:
Undemanding; a single balanced feed and a mulch of compost in spring is usually enough. Over-feeding, especially with nitrogen, produces lush growth at the expense of flowers and seedheads. A light potassium feed can boost flowering on poor soils. In practice: no routine feeding at all for clematis tangutica — at most a thin compost mulch for soil structure, never a flowering or nitrogen feed.
The dormant-season rule matters more than the exact interval: skip feeding entirely when clematis tangutica 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 clematis tangutica
None is the correct answer for clematis tangutica. The flower-versus-foliage trade-off is the whole point: hold back and you get the display.
Feeding always goes onto already-damp soil, never dry roots — water clematis tangutica first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the clematis tangutica watering schedule.
Signs you are over-feeding clematis tangutica
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for clematis tangutica:
- Abundant leafy growth and very few flowers (the classic over-rich symptom).
- Soft, floppy stems and a sprawling, leafy habit.
- Scorched edges and salt crust if it has been fed in a container.
Signs you are under-feeding clematis tangutica
- Effectively never an issue — these plants flower on poverty.
- Only on genuinely dead soil: weak, thin growth and few blooms.
- A short-lived plant in completely spent container compost.
If the symptoms point at watering, light or roots rather than nutrition, the full clematis tangutica care brief covers soil, humidity and the common problems for this species.
Flushing and leaching the salts
If clematis tangutica has accidentally been fed and is all leaf, a plain-water flush plus a move to leaner soil resets it; otherwise no flushing is needed because you are not feeding it.
Organic vs synthetic feeds for clematis tangutica
Organic options
A thin compost mulch for soil structure is the absolute most; mostly, give it nothing. UK/US: leave it lean — no manure, no liquid feed. Poor soil is the active ingredient here.
Synthetic / liquid feeds
None. Synthetic feeds, particularly anything with appreciable nitrogen, directly suppress flowering in clematis tangutica.
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 clematis tangutica look like?
Abundant leafy growth and very few flowers (the classic over-rich symptom). Soft, floppy stems and a sprawling, leafy habit. Scorched edges and salt crust if it has been fed in a container. Feeding clematis tangutica at all — especially "to help it flower" — is the defining mistake. Rich soil gives you a big green plant and almost no blooms; restraint is what produces the flowers.
Should I flush the soil of clematis tangutica?
If clematis tangutica has accidentally been fed and is all leaf, a plain-water flush plus a move to leaner soil resets it; otherwise no flushing is needed because you are not feeding it.
