Bushgrass (Reed small-reed) care

Light

Bushgrass wants the spot a few feet back from a sunny window — bright enough to read a paperback at noon, but the sun never falls directly on the leaves. One of the most shade-tolerant ornamental grasses; performs well in dappled woodland shade or the dry shade beneath tree canopies where few other grasses thrive; tolerates full sun if moisture is adequate. A faint hand shadow at midday is the right amount; a sharp dark shadow means it's getting direct sun and probably too much.

Watering

Water bushgrass moderate — water regularly to establish, then largely drought-tolerant. 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. Once established (after the first growing season) it tolerates periods of drought, especially in shade; water young plants weekly during dry periods in the first year to encourage deep rooting.

Soil and pot

Bushgrass grows best in well-drained to moderately moist loam or sandy loam; tolerates dry soils. Adaptable to a wide range of soil types including dry, infertile soils under trees; good drainage is preferred as prolonged waterlogging is poorly tolerated. 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

Bushgrass sits happiest at around 40–70% humidity and -20 to 35°C (-4 to 95°F). Undemanding in terms of humidity; performs well under typical UK and northern US outdoor conditions without supplemental humidity. 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 bushgrass sparingly. Feed with a balanced granular fertiliser in early spring only if soil is poor; in fertile garden soils, no supplementary feeding is needed and excess nitrogen produces lax, floppy 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 bushgrass in the Growli community. Each is annotated with the most common cause so you know where to start.

• Powdery mildew on foliage — White powdery coating on leaves appears in warm, dry conditions with poor air circulation; improve spacing, avoid overhead watering late in the day, and remove severely affected foliage.
• Crown rot in waterlogged soil — Though tolerant of dry shade, this species dislikes prolonged waterlogging; if planted in heavy clay with poor drainage, crowns may rot — improve drainage with grit or raised planting.

Propagation

Divide established clumps in early spring as new growth emerges, splitting the rootball into sections with a sharp spade; replant promptly at the original depth. Can also be grown from seed sown in spring at 15–20°C (59–68°F), though cultivar selection requires vegetative propagation. 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

Bushgrass is pet-safe. Calamagrostis species are not listed on the ASPCA Toxic and Non-Toxic Plant database as toxic to cats or dogs; this grass is considered non-toxic to 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.
