About Humulus lupulus 'Aureus'

Humulus lupulus 'Aureus' · also called golden hops, yellow hops vine · flowering

Humulus lupulus 'Aureus', golden hops, is a fast herbaceous perennial climber grown for its luminous golden-yellow foliage rather than its cones. Vigorous twining bines clothe arches and trellis in lime-gold lobed leaves through summer before dying back in winter. It holds the RHS Award of Garden Merit for its dependable ornamental colour.

Growth habit: Herbaceous perennial bine that twines clockwise up supports with bristly stems; dies back to the rootstock each winter and regrows rapidly each spring.

Watch for — Loss of gold colour: Too much shade or excess nitrogen turns leaves green. Site in good sun and feed moderately to keep the bright colour.

What fertiliser humulus lupulus 'aureus' actually wants — and why

Humulus lupulus 'Aureus' 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 humulus lupulus 'aureus': 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 humulus lupulus 'aureus', 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 humulus lupulus 'aureus':

Apply a balanced feed in spring and mulch with compost to sustain vigorous growth; avoid excess nitrogen, which can dull the golden colour. A midsummer feed keeps foliage strong. 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 humulus lupulus 'aureus' 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 humulus lupulus 'aureus'

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

Signs you are over-feeding humulus lupulus 'aureus'

Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for humulus lupulus 'aureus':

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

Flushing and leaching the salts

Flush the pot of humulus lupulus 'aureus' 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 humulus lupulus 'aureus'

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.

Half strength is the safe default for humulus lupulus 'aureus' — houseplant feeds are formulated strong, and the diluted dose is gentler on the roots while still ample for foliage.

What does over-feeding humulus lupulus 'aureus' 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 humulus lupulus 'aureus' 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 humulus lupulus 'aureus'?

Flush the pot of humulus lupulus 'aureus' 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.
