Growth Stages

1

Germination & Seedling

7-14 days

Seeds sprout in 7-10 days; tiny cotyledons emerge followed by first true leaves with characteristic savoyed texture beginning to show

Keep soil evenly moist; thin seedlings when they develop 2-3 true leaves to prevent crowding and disease; provide bright light

2

Vegetative Growth

3-4 weeks

Plant develops multiple true leaves with distinctive wrinkled, dark green appearance; rosette expands; roots establish

Maintain consistent moisture and cool temperatures (50-70°F ideal); fertilize with nitrogen-rich fertilizer every 2-3 weeks; ensure good air circulation; mulch to retain moisture and keep soil cool

3

Pre-Harvest Maturity

1-2 weeks

Leaves reach full size and color intensity; plant develops 6-10 mature leaves; basal leaves are largest and most tender

Monitor for pest activity; continue consistent watering; this variety's bolt resistance allows slightly warmer temperatures than other spinach types; begin selective harvesting of outer leaves

4

Harvest Ready

2-4 weeks or more

Fully mature plant with abundant, deeply savoyed dark green leaves; plant is dense and productive; bolting is minimal due to variety characteristics

Harvest regularly to encourage continued leaf production; pick outer leaves first to extend harvest window; cooler fall temperatures extend harvest period; remove any flower buds immediately if they appear

5

Post-Harvest / Bolting

Variable; depends on temperature

If left unharvested in warm weather, plant develops flowering stems (bolts); leaves become tougher and bitter; 'Long Standing' trait delays this more than other varieties

Harvest before bolting occurs for best quality; once bolting starts, plant productivity declines; allow a few plants to bolt for seed collection if desired

Common Pests

  • Spray with insecticidal soap or neem oil; introduce ladybugs; use reflective mulches; strong water spray dislodges pests

  • Remove affected leaves immediately; use row covers to prevent egg-laying; remove weeds that harbor pupae; spinosad as organic option

  • Use row covers on seedlings; apply kaolin clay spray; neem oil spray; encourage natural predators

  • Maintain humidity and consistent watering; spray with water; neem oil or insecticidal soap; encourage predatory mites

  • Ensure good air circulation; avoid overhead watering; remove infected leaves; apply sulfur dust; choose resistant varieties when possible

Uses

🍳

Fresh Salads & Raw Consumption

Culinary

The deeply savoyed leaves of Bloomsdale Long Standing add visual appeal and tender texture to salads and fresh greens mixes. The dark green color indicates high nutrient density, making it a nutritious raw choice. [source]

🍳

Cooked & Wilted Dishes

Culinary

Mature leaves are ideal for cooking, as the crumpled texture softens beautifully when wilted into soups, stir-fries, casseroles, and pasta dishes. This variety is a traditional choice for creamed spinach and spinach souffle. [source]

💊

Iron & Micronutrient Source

Medicinal

Spinach is rich in iron, magnesium, calcium, and antioxidants including lutein and zeaxanthin, which support eye health and overall wellness. The dark green coloring indicates high chlorophyll content. [source]

🍳

Smoothies & Blended Beverages

Culinary

The tender leaves (especially baby leaf stage) blend smoothly into green smoothies and health drinks with minimal grittiness. High nutrient content makes this an excellent superfood addition. [source]

🏠

Seed Production & Saving

Household

As a 'Long Standing' heirloom variety, Bloomsdale can be left in the garden to bolt and produce seed for future seasons, offering cost savings and self-sufficiency in propagation. [source]

Harvest Tips

Begin harvesting outer leaves when plant reaches 3-4 inches tall (baby leaf stage at 30 days) or wait for full maturity at 40-50 days. Harvest in early morning when leaves are crisp and cool for best quality. Pick outer leaves first, leaving inner leaves to continue growing. Cut or pinch leaves 1 inch above soil line. The 'Long Standing' characteristic means this variety resists bolting longer than standard spinach, extending the harvest window by 2-3 weeks. Harvest regularly to encourage new leaf production. If temperatures exceed 75°F consistently, harvest all remaining leaves before plant bolts.

Fun Facts

  • 🌱 The 'Bloomsdale' variety was introduced in 1925 and remains one of the most popular heirloom spinach varieties over 100 years later, prized by gardeners for its reliability and flavor.
  • 🌱 The deeply savoyed (wrinkled) leaves of spinach are not just ornamental—they increase surface area, making the plant more efficient at photosynthesis and improving cooking texture.
  • 🌱 Spinach is technically a cool-season annual, but the 'Long Standing' trait means this variety can produce harvestable leaves 2-3 weeks longer into warming temperatures than other spinach types before bolting and flowering.
