About Gollum Jade
Crassula ovata 'Gollum' · also called Trumpet Jade, ET's Fingers · houseplant
Gollum Jade is a sculptural jade cultivar with tubular, finger-like leaves flared into suction-cup tips, often rimmed red in bright light. A slow, woody, tree-like succulent, it can bloom with starry white-pink flowers when mature. Easy and long-lived but, like all Crassula ovata, ASPCA-listed as toxic to cats and dogs.
Growth habit: Slow-growing, branching, tree-like succulent with a thick woody trunk and upright fingered branches; develops a bonsai-like form with age.
What fertiliser gollum jade actually wants — and why
Gollum Jade is a light-feeding succulent — a gentle, low-nitrogen feed a few times in growth keeps it plump without forcing the weak, stretched growth over-feeding causes.
A cactus and succulent formula or a diluted balanced feed with modest, even numbers. Avoid high-nitrogen plant foods — they make a succulent etiolate and grow soft, fracture-prone tissue.
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 gollum jade: 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 gollum jade, 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 gollum jade:
Light. Feed with a dilute balanced or cactus fertiliser once a month during spring and summer growth only; none in autumn and winter. Keep that to once a month between spring through early autumn (roughly March to September) and stop entirely once growth slows for winter.
The dormant-season rule matters more than the exact interval: skip feeding entirely when gollum jade 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 gollum jade
Quarter to half strength at most for gollum jade. Succulents take up very little, and a strong dose burns the fine roots before the plant can use it.
Feeding always goes onto already-damp soil, never dry roots — water gollum jade first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the gollum jade watering schedule.
Signs you are over-feeding gollum jade
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for gollum jade:
- Stretched, leggy, pale growth with widely spaced leaves.
- A white salt crust on the soil or around the pot rim.
- Brown, crisped leaf tips and edges.
- Soft, mushy tissue at the base — over-feeding plus damp soil rots it.
Signs you are under-feeding gollum jade
- Uncommon — succulents tolerate lean conditions well.
- Very slow growth and dull, faded colour over a long period.
- Older leaves shed faster than new ones replace them in a tired old mix.
If the symptoms point at watering, light or roots rather than nutrition, the full gollum jade care brief covers soil, humidity and the common problems for this species.
Flushing and leaching the salts
Feed lightly enough and you rarely need to flush, but once a year run plain water through the pot of gollum jade until it drains clear, and refresh the gritty mix every 2-3 years.
Organic vs synthetic feeds for gollum jade
Organic options
A heavily diluted seaweed or worm-casting feed once or twice in summer. UK: a drop of Westland seaweed feed; US: quarter-strength Espoma Cactus! or Dr. Earth liquid. Fresh free-draining mix matters more than any feed.
Synthetic / liquid feeds
A dedicated cactus/succulent liquid at quarter to half strength — UK: Baby Bio Cacti & Succulent Drip Feeders or Westland; US: Miracle-Gro Succulent Plant Food or Schultz Cactus Plus.
Brand names are examples, not endorsements, and UK and US ranges differ — check the label’s own NPK and dilution rate, since formulations change.

Soft, mushy tissue at the base — over-feeding plus damp soil rots it. Feeding gollum jade like a leafy houseplant is the classic error — it produces a flush of pale, stretched, floppy growth that never firms up and is prone to rot at the base.
Should I flush the soil of gollum jade?
Feed lightly enough and you rarely need to flush, but once a year run plain water through the pot of gollum jade until it drains clear, and refresh the gritty mix every 2-3 years.
