Bob Gordon Elderberry (Bob Gordon Elder) care

Light

Bob Gordon Elderberry needs sun on the leaves, not just bright ambient room light. Requires full sun — minimum 6 hours of direct sunlight daily. Adequate light is directly correlated with flower density and therefore fruit yield. Avoid sites shaded by buildings or dense tree canopy. A south or west-facing windowsill in the northern hemisphere is the default; anywhere else, expect the plant to stretch and pale out within a season.

Watering

Outdoor bob gordon elderberry crops want weekly during dry periods, especially may through august. The single best habit is a finger-test before watering — push a finger 3-4 cm into the soil. Damp = wait a day; dust-dry = water deeply at the base of the plant. Consistent moisture through flowering and fruit development is essential for maximum berry yield. Drip irrigation is ideal for production settings. Mulch heavily around the base to conserve soil moisture and regulate root temperature.

Soil and pot

Bob Gordon Elderberry grows best in fertile, moist, well-drained loam; ph 5.5–6.5. Thrives in organically rich soils. Prepare planting holes with generous compost incorporation. Tolerates heavier clay soils if not persistently waterlogged. Avoid thin, sandy, drought-prone soils which significantly reduce yields on this cultivar. 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

Bob Gordon Elderberry sits happiest at around 40–80% humidity and -30–35°C (-22–95°F). Well-adapted to the temperate continental humidity ranges of the Midwest and similar climates. No special humidity management is required. Prune for open cane structure to reduce foliar disease risk in humid sites. 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 bob gordon elderberry sparingly. In early spring apply a balanced fertiliser (e.g. 10-10-10 at the label rate for shrubs). In productive stands, a supplemental potassium feed at flowering helps berry development. Avoid heavy nitrogen in late season. 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 bob gordon elderberry in the Growli community. Each is annotated with the most common cause so you know where to start.

• Low fruit set without a pollinator — Bob Gordon is not reliably self-fertile. Plant a second cultivar (Adams, Nova, or York) within 15–20 m to ensure cross-pollination and maximise berry cluster size and fruit set.
• Cane borer damage — Desmocerus palliatus (elderberry borer) larvae cause cane wilting from the crown down. Remove and destroy affected canes at ground level promptly. Vigorous, well-fed plants recover quickly.
• Leaf curl from aphids — Black bean aphids colonise new shoot tips, causing leaf curl and distorted growth. Treat early with insecticidal soap or neem oil. Established plants rarely suffer serious long-term damage.

Propagation

Hardwood cuttings 20–30 cm long taken in late autumn root reliably in free-draining compost over winter in a cold frame. Softwood cuttings in early summer root under mist with bottom heat. Rooted suckers can be detached and transplanted in early spring. 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

Bob Gordon Elderberry is mildly toxic to pets. Sambucus is listed by ASPCA as toxic to dogs and cats. Raw plant material including leaves, bark, unripe berries, and roots contains sambunigrin (a cyanogenic glycoside) that can cause vomiting, diarrhoea, and lethargy. Ripe, cooked berries are used in human food products, but the raw plant must be kept out of reach of 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.
