About Cercidiphyllum japonicum 'Pendulum'

Cercidiphyllum japonicum 'Pendulum' · also called Weeping Katsura · flowering

The weeping form of the katsura, forming a dramatic dome or cascade of arching, trailing branches clothed in rounded heart-shaped leaves. Foliage emerges bronze, matures blue-green and colours to yellow and apricot-pink in autumn, releasing the characteristic burnt-sugar scent as it falls. A graceful, sculptural specimen for moist, sheltered gardens, often top-grafted to control its height.

Growth habit: Strongly weeping deciduous tree; top-grafted plants form a fountain or mushroom of cascading branches to the ground, while non-grafted plants mound and sprawl.

Watch for — Chlorosis on chalk: Pale leaves on shallow alkaline soil indicate iron lock-out; grow on acid-to-neutral soil or correct with chelated iron and acidic mulch.

What fertiliser cercidiphyllum japonicum 'pendulum' actually wants — and why

Cercidiphyllum japonicum 'Pendulum' 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 cercidiphyllum japonicum 'pendulum': 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 cercidiphyllum japonicum 'pendulum', 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 cercidiphyllum japonicum 'pendulum':

An annual spring mulch of leaf mould or compost is usually enough; on poorer soils add a balanced slow-release feed in early spring. Maintaining cool, moist roots matters more than heavy feeding for this drought-sensitive tree. 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 cercidiphyllum japonicum 'pendulum' 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 cercidiphyllum japonicum 'pendulum'

Half strength is the safe default for cercidiphyllum japonicum 'pendulum' — 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 cercidiphyllum japonicum 'pendulum' first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the cercidiphyllum japonicum 'pendulum' watering schedule.

Signs you are over-feeding cercidiphyllum japonicum 'pendulum'

Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for cercidiphyllum japonicum 'pendulum':

Signs you are under-feeding cercidiphyllum japonicum 'pendulum'

If the symptoms point at watering, light or roots rather than nutrition, the full cercidiphyllum japonicum 'pendulum' care brief covers soil, humidity and the common problems for this species.

Flushing and leaching the salts

Flush the pot of cercidiphyllum japonicum 'pendulum' 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 cercidiphyllum japonicum 'pendulum'

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 fertiliser does cercidiphyllum japonicum 'pendulum' need?

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.

What does over-feeding cercidiphyllum japonicum 'pendulum' 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 cercidiphyllum japonicum 'pendulum' 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 cercidiphyllum japonicum 'pendulum'?

Flush the pot of cercidiphyllum japonicum 'pendulum' 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.
