Nandina Obsessed (Obsessed Nandina) care

Light

Aim for at least 4-6 hours of direct sun on the leaves. Full sun produces the strongest, most repeated red colour flushes. It tolerates partial shade but new growth is less intensely coloured; give at least 6 hours of direct sun where possible. If your only bright window faces south, that's perfect for nandina obsessed — same window any aroid would fry on.

Watering

Watering nandina obsessed: weekly while establishing, then every 10-14 days once mature. The number that matters isn't the day of the week — it's how dry the top 2-3 cm of the pot feels. A finger in the soil tells you more than a watering app. After every watering, tip the saucer. Maintain steady moisture during the first season to settle the roots. Once established it handles drought well; water deeply but infrequently, allowing the top of the soil to dry between waterings.

Soil and pot

Nandina Obsessed grows best in well-drained, moderately fertile loam. Tolerates a wide range of soils including clay, but grows best in slightly acidic to neutral, free-draining ground enriched with organic matter. Mulch to retain moisture and avoid soggy conditions. 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

Nandina Obsessed sits happiest at around Ambient outdoor humidity and -15 to 35°C (5 to 95°F). An outdoor shrub with no special humidity needs; copes equally with humid summers and dry-climate gardens. If you keep the room above 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 nandina obsessed sparingly. Apply a balanced slow-release shrub fertiliser once in early spring. Keep feeding light — over-fertilising mutes the signature red flushes and forces leggy growth. A spring compost mulch supports steady, colourful growth. 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 nandina obsessed in the Growli community. Each is annotated with the most common cause so you know where to start.

• Weak red flushes — Shade and excess nitrogen suppress the vivid new-growth colour. Move to full sun and limit feeding to restore the bright red flushes.
• Leaf scorch in winter — Cold, drying winds can brown leaf edges in exposed sites. Provide shelter and ensure plants are watered going into freezing weather.
• Chlorosis — Yellowed leaves with green veins signal iron deficiency on alkaline or waterlogged soil. Improve drainage and apply chelated iron.
• Legginess if neglected — Skipping pruning lets stems thin and stretch. A light spring trim of the tallest canes keeps 'Obsessed' compact and well-branched.

Propagation

Propagate by semi-hardwood cuttings in summer under mist, or by division of established clumps in spring. The cultivar is patented in some markets and does not come true from seed, so vegetative propagation is required. 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

Nandina Obsessed is toxic to pets. ASPCA lists Nandina (Nandina domestica) as toxic to dogs, cats, and horses. The toxic principle is cyanogenic glycosides; signs include weakness, incoordination, seizures, coma, and respiratory failure (death rare in pets). Although fruiting is sparse on this compact cultivar, all parts are toxic — keep away from pets. 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.
