Zinnia elegans 'Profusion Cherry' (Profusion Cherry Zinnia) care

Light

Aim for at least 4-6 hours of direct sun on the leaves. Full direct sun, 6+ hours daily, for peak flowering and best disease resistance. It thrives in heat; shade reduces blooms and weakens the plant. If your only bright window faces south, that's perfect for zinnia elegans 'profusion cherry' — same window any aroid would fry on.

Watering

Watering zinnia elegans 'profusion cherry': when the top 3-4 cm of soil is dry, about every 5-7 days. 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. Water deeply at the base and allow the surface to dry between waterings. Notably drought-tolerant once established, it dislikes constantly wet soil. Keeping foliage dry preserves its strong mildew resistance.

Soil and pot

Zinnia elegans 'Profusion Cherry' grows best in well-drained, average garden soil or quality container compost. Adaptable and undemanding; prefers free-draining soil at pH 5.5-7.5. It performs well even in lean soils, far more forgiving than tall florist zinnias. 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

Zinnia elegans 'Profusion Cherry' sits happiest at around 30-60% humidity and 18-32°C (65-90°F). An outdoor annual indifferent to ambient humidity. Its angustifolia parentage gives it strong tolerance of the humid, muggy conditions that usually trigger zinnia mildew. If you keep the room above 18 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 zinnia elegans 'profusion cherry' sparingly. Light feeder. A balanced feed worked into the bed at planting, plus a monthly half-strength liquid feed for containers, keeps it blooming. It flowers abundantly on little feed; avoid excess nitrogen. 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 zinnia elegans 'profusion cherry' in the Growli community. Each is annotated with the most common cause so you know where to start.

• Overwatering and root rot — Constantly wet or poorly drained soil rots the roots. Let soil dry between waterings and ensure containers drain freely.
• Fewer blooms in low light — Insufficient sun reduces flowering and the plant's natural vigour. Grow in full sun for nonstop bloom.
• Aphids — Aphids may gather on tender new growth and buds. Dislodge with a strong water spray or treat with insecticidal soap.
• Spider mites in heat — Prolonged hot, dry spells can bring mites that stipple leaves. Rinse foliage and use neem or insecticidal soap if needed.

Propagation

Grown from seed. Sow indoors 4-6 weeks before last frost in modules to avoid root disturbance, or direct-sow into warm soil afterwards. Germinates in 5-7 days at 21-24°C. As an F1 interspecific hybrid it is largely sterile and seed-saving is unreliable; buy fresh seed annually. 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

Zinnia elegans 'Profusion Cherry' is pet-safe. Zinnia is ASPCA-listed as non-toxic to cats, dogs and horses. At most, nibbling causes mild, short-lived stomach upset; the plant is not poisonous. 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.
