Growth Stages

1

Germination & Seedling

2-3 weeks

Seeds sprout within 7-10 days. First true leaves (cotyledons) appear, followed by serrated true leaves. Seedlings are delicate with thin stems.

Keep soil consistently moist but not saturated. Maintain soil temperature 50-70°F for best germination. Thin seedlings to proper spacing once they have 2-3 true leaves.

2

Vegetative Growth

3-4 weeks

Plant develops dense rosette of dark green, crinkled leaves. Leaf production accelerates as temperatures cool. Plant builds a strong root system.

Ensure consistent watering and adequate nitrogen for vigorous leaf growth. Remove any weeds competing for nutrients. Mulch to retain moisture and maintain cool soil temperature.

3

Mature Leaf Production

2-4 weeks

Plant reaches full size with maximum leaf density. Leaves are fully darkened and have excellent flavor and tenderness. Plant is ready for harvest.

Begin harvesting outer leaves to encourage continued production. Maintain consistent moisture. Monitor for bolting, especially if temperatures spike above 75°F.

4

Peak Harvest

2-3 weeks

Optimal window for harvesting mature leaves. Plant is productive and flavorful. Bolting has not yet begun (if conditions remain cool).

Harvest regularly to promote further leaf production and delay bolting. Pick outer leaves first, leaving inner growth point intact. Harvest in early morning for crispest texture.

5

Bolting/Maturation

Ongoing once initiated

Plant sends up flower stalk as temperatures warm or day length increases. Leaves become more bitter and plant energy shifts to seed production.

Once bolting begins, quality declines. Remove bolting plants to make room for new succession plantings. Waldmann's Green is slow-bolting, extending harvest compared to other varieties.

  • and

    Handpick in early morning or evening. Use beer traps or copper tape barriers. Keep area free of excessive debris and moisture.

  • Use row covers on young plants. Dust with food-grade diatomaceous earth. Plant trap crops nearby. Remove plant debris.

  • Control aphid vectors with organic sprays. Remove infected plants immediately. Maintain good plant spacing for air circulation.

Harvest Tips

Begin harvesting outer leaves when plant has 6-8 leaves, typically 40-50 days after planting. Harvest in early morning when leaves are crisp and hydrated. Pinch or cut outer leaves at the base, leaving the inner rosette to continue growing. For baby spinach, harvest entire small plants. Waldmann's Green continues producing through cool weather; succession plant every 2-3 weeks for continuous harvest. Stop harvesting once bolting begins.

Fun Facts

  • 🌱 Waldmann's Green was developed in Germany and is prized in European markets; it's also called 'Waldmannsspinach' in German-speaking countries and represents decades of breeding for cold hardiness and slow bolting.
  • 🌱 This variety is exceptionally cold-hardy and can survive temperatures down to 15-20°F (-9 to -7°C), making it one of the best choices for winter gardening in cold climates and fall-to-spring production.
  • 🌱 The popular claim that spinach is extremely high in iron originated from a decimal point error in 1870s research; however, spinach is still a very good iron source, and Waldmann's Green's tender leaves make iron absorption easier than tougher spinach varieties.
