Hydrangea aspera 'Villosa' (rough-leaved hydrangea) care

Light

Hydrangea aspera 'Villosa' 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. Grows best in dappled or partial shade with shelter from cold winds and hot midday sun, which scorches the soft foliage and flowers. Morning sun with afternoon shade is ideal; deep shade reduces flowering. A phone lux-meter at the leaf surface should read 1,500-3,000 lux at noon.

Watering

Water hydrangea aspera 'villosa' keep evenly moist; water deeply every 5-7 days in dry summer spells. The actual day count varies with pot size, light, and season — the finger test (or lifting the pot to feel its weight) is more reliable than a fixed calendar. Empty any drainage saucer afterwards so the pot isn't sitting in water. Needs consistently moist soil and dislikes drying out, wilting quickly in heat. Mulch to conserve moisture and water generously during droughts, but ensure the soil drains so roots never sit waterlogged.

Soil and pot

Hydrangea aspera 'Villosa' grows best in moist, humus-rich, well-drained loam. Prefers fertile, organic-rich soil. Unusually for a hydrangea it tolerates chalk and alkaline soils as well as neutral to acid ground. Enrich with leaf mould or compost and mulch to retain moisture. 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

Hydrangea aspera 'Villosa' sits happiest at around 50-70% humidity and -15 to 30°C (5 to 86°F). Appreciates the steady moisture of a sheltered woodland setting; thrives in typical UK humidity. In hot, dry, exposed positions the felted leaves scorch, so shelter matters more than misting. 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 hydrangea aspera 'villosa' sparingly. Feed in spring with a balanced slow-release fertiliser and an annual mulch of well-rotted compost or leaf mould. Avoid excessive feeding; steady fertility supports the large leaves and late flowers. 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 hydrangea aspera 'villosa' in the Growli community. Each is annotated with the most common cause so you know where to start.

• Leaf scorch and wilting — The soft, felted leaves brown and crisp in hot sun, wind or drought. Plant in sheltered dappled shade and keep the soil reliably moist.
• Frost damage to young growth — Late spring frosts blacken emerging shoots and can reduce flowering. Site in a sheltered spot and avoid frost pockets; it is less hardy than mophead hydrangeas.
• No flowers after wrong pruning — It blooms on old wood, so cutting back hard in spring removes the buds. Prune lightly, taking out only spent heads and dead stems.
• Aphids on soft growth — Tender new shoots attract aphids that distort growth and leave honeydew. Rinse off or use insecticidal soap; predators usually help control them.

Propagation

Propagate from softwood cuttings in early summer, taken from non-flowering shoots and rooted under cover. Semi-ripe cuttings in late summer also work; cuttings keep the named selection true to type. 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

Hydrangea aspera 'Villosa' is toxic to pets. The ASPCA lists Hydrangea as toxic to dogs, cats and horses. The toxic principle is cyanogenic glycoside (hydrangin) present in leaves, buds and flowers; ingestion can cause vomiting, diarrhoea, lethargy and depression. Keep pets from chewing the plant and contact a vet if a significant amount is eaten. 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.
