Care at a glance
Light
Gollum Jade is what florists mean by "bright spot, no direct sun" — close enough to a south or east window to feel the brightness, with a sheer curtain or a few feet of distance keeping the sun off the leaves. Bright light with several hours of direct sun; a sunny window or full sun outdoors. Strong light keeps it compact and reddens the leaf tips. Low light causes stretching and leaf drop. A phone lux-meter at the leaf surface should read 1,500-3,000 lux at noon.
Watering
Water gollum jade when the top 3-5 cm of soil is fully dry, roughly every 2-3 weeks; less in winter. Succulent-style plants store water in stem and leaf tissue — they'd rather be slightly thirsty than slightly soggy, and the most common way to kill one is to water it on a fixed weekly calendar instead of by feel. Water thoroughly then let the soil dry out completely. Plump leaves store water, so err dry. Overwatering and wet soil are the main killers; cut back sharply in winter dormancy.
Soil and pot
Gollum Jade grows best in free-draining cactus/succulent mix. Cactus compost or a gritty blend with extra perlite, pumice or coarse sand in a pot with drainage holes. Never let it sit in saturated or water-retentive soil. A pot with a working drainage hole is non-negotiable for this species — even free-draining mix will turn soggy in a closed planter. If you love the look of a decorative pot without a hole, use it as a cachepot around an inner nursery pot you can lift out to water.
Humidity and temperature
Gollum Jade sits happiest at around 30-50% humidity and 10-27°C (50-80°F). Prefers average-to-dry household air. Indifferent to low humidity and dislikes damp, stagnant conditions, which encourage rot and fungal issues. If you keep the room above 10 year-round and avoid placing the plant near a cold draught, a hot radiator, or an air-conditioning vent, you have already handled the two biggest indoor stressors.
Fertilising
Feed gollum jade sparingly. Light. Feed with a dilute balanced or cactus fertiliser once a month during spring and summer growth only; none in autumn and winter. Skip fertiliser entirely on a stressed, recently-repotted, or actively wilting plant — fertiliser salts make damage worse, not better. Wait for a round of healthy new growth before resuming a feeding rhythm.
Common problems
Below are the issues we see most often on gollum jade in the Growli community. Each is annotated with the most common cause so you know where to start.
- Wrinkled, dropping leaves from overwatering — Counterintuitively, soft mushy leaves and stem rot signal too much water. Let soil dry fully and improve drainage.
- Stretching and leaf drop — Insufficient light. Move to a sunny window or supplement with a grow light to keep growth compact.
- Mealybugs — White cottony pests gather in leaf joints. Wipe off with alcohol on a cotton swab and treat repeatedly until clear.
- Black spots or soft trunk — Rot from cold, wet soil. Cut away affected tissue, dry out, and re-root healthy cuttings if needed.
Propagation
Easy from stem or leaf cuttings. Let the cut callus for a few days, then set in dry gritty mix and water sparingly once roots form. Best in spring and summer. Propagation is the cheapest, most satisfying way to expand a collection — and it doubles as insurance against losing a mature plant to an accident. Take a backup cutting once the parent is established and healthy.
Toxicity to pets
Gollum Jade is toxic to pets. ASPCA-listed as toxic to cats, dogs and horses (jade plant, Crassula ovata). Toxic principle is unknown; reported signs include vomiting, depression/lethargy and incoordination. Keep out of pets' reach. If you keep cats, dogs, or curious children in the house, weigh placement carefully — a high shelf or a hanging planter is enough for casual safety. For severe ingestion incidents, call your local vet and the ASPCA Animal Poison Control Center (in the US, 888-426-4435).
Pet-safety status is sourced from the ASPCA Toxic and Non-Toxic Plant List, which catalogues the most-asked-about plants for cats, dogs, and horses.
Gollum Jade care — frequently asked questions
What is the common name for Crassula ovata 'Gollum'?
Crassula ovata 'Gollum' is most commonly called Gollum Jade, but it is also known as Trumpet Jade, ET's Fingers. The names refer to the same species, so care instructions for Gollum Jade apply identically to anything sold as Trumpet Jade.
How much light does gollum jade need?
Gollum Jade grows best in bright indirect light (just back from a sunny window). Bright light with several hours of direct sun; a sunny window or full sun outdoors. Strong light keeps it compact and reddens the leaf tips. Low light causes stretching and leaf drop.
How often should I water gollum jade?
Water gollum jade when the top 3-5 cm of soil is fully dry, roughly every 2-3 weeks; less in winter. Water thoroughly then let the soil dry out completely. Plump leaves store water, so err dry. Overwatering and wet soil are the main killers; cut back sharply in winter dormancy. The finger-test (or lifting the pot to feel its weight) beats a fixed weekly calendar because pot size, light, and season all change how fast the soil dries.
Is gollum jade toxic to cats and dogs?
Gollum Jade is toxic to pets. ASPCA-listed as toxic to cats, dogs and horses (jade plant, Crassula ovata). Toxic principle is unknown; reported signs include vomiting, depression/lethargy and incoordination. Keep out of pets' reach.
