Bloomsdale Spinach (Bloomsdale Long Standing Spinach) care

Light

Aim for at least 4-6 hours of direct sun on the leaves. Grows best in full sun (6+ hours daily) in spring and autumn. In late spring, light afternoon shade can extend the harvest window before heat triggers bolting. If your only bright window faces south, that's perfect for bloomsdale spinach — same window any aroid would fry on.

Watering

Crops like bloomsdale spinach reward consistent watering — 2–3 times per week. The mistake is the daily light sprinkle: it never reaches the deeper roots. A long soak twice a week beats a five-minute splash every day. Keep soil consistently moist but not waterlogged. Uneven watering stresses plants and accelerates bolting. Water at the base to reduce disease risk on the crinkled leaf surfaces.

Soil and pot

Bloomsdale Spinach grows best in rich, well-draining loam. pH 6.5–7.0 (spinach is sensitive to acidic soils — lime if below 6.0). Add compost before sowing. Loose, fertile soil encourages the deep taproot that supports Bloomsdale's vigorous frame. 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

Bloomsdale Spinach sits happiest at around 40–70% humidity and 2–18°C (35–65°F). Tolerates a range of outdoor humidity. Savoy (crinkled) leaves can trap moisture, increasing downy mildew risk in very humid conditions. Ensure adequate spacing and airflow. If you keep the room above 2–18°C 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 bloomsdale spinach sparingly. Work a balanced granular fertiliser (5-10-10) into the soil before sowing. Liquid nitrogen feed every 3 weeks promotes dark, lush growth. Avoid heavy feeding late in the season as it can encourage soft, disease-prone leaves. 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 bloomsdale spinach in the Growli community. Each is annotated with the most common cause so you know where to start.

• Bolting — Long days (14+ hours) and temperatures above 24°C (75°F) trigger premature flowering and bitter leaves. Bloomsdale's superior bolt resistance buys extra time, but spring sowing should target harvest before midsummer.
• Downy mildew — Yellow patches on leaf surfaces with grey mould beneath, most severe in cool, wet conditions. Bloomsdale has some tolerance; maximise airflow and avoid overhead irrigation. Remove affected leaves immediately.
• Leaf miner — White, winding tunnels on leaves caused by Pegomya hyoscyami fly larvae. Cover with fine insect mesh from sowing. Remove and destroy affected leaves; do not compost them.

Propagation

Direct-sow seeds 1–2 cm (½ in) deep in rows 30 cm (12 in) apart from early spring (as soon as soil reaches 4°C/40°F) or from late summer for an autumn crop. Thin to 8–10 cm (3–4 in) apart. Germination: 7–14 days. Does not transplant well; direct sowing is strongly preferred. 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

Bloomsdale Spinach is pet-safe. Spinacia oleracea is not listed as toxic to cats or dogs by the ASPCA. However, spinach contains oxalic acid — large quantities are inadvisable for pets with kidney disease or prone to urinary crystals. Occasional small amounts pose no risk to healthy animals. 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.
