Growth Stages

1

Seedling

7-10 days

Tiny seedlings emerge with fine cotyledons and true leaves begin appearing. Foliage is delicate and light green.

Keep soil consistently moist. Provide bright light to prevent leggy growth. Thin seedlings to proper spacing once they have 2-3 true leaves.

2

Vegetative Growth

15-25 days

Plant develops multiple stems with feathery, deeply lobed leaves. Foliage becomes thicker and bushier with each passing week.

Begin light harvesting of outer leaves once plant has 6-8 leaves. Water consistently and fertilize every 2-3 weeks with balanced fertilizer. Pinch back growing tips to encourage bushiness.

3

Peak Harvest

20-30 days

Plant is full and lush with abundant tender leaves ready for harvest. Foliage is bright green with characteristic aromatic scent.

Harvest frequently (every 3-5 days) to promote continuous leaf production and prevent flowering. Remove outer leaves first, working from bottom up.

4

Bolting/Flowering

Variable; occurs in warm weather or after extended growth period

If not harvested regularly, plant sends up flowering stems with small yellow or white chrysanthemum-like flowers.

Once flowering begins, quality and flavor of leaves decline. Remove flowers if you want to continue harvesting leaves, or allow flowering to complete seed cycle.

5

Seed Production

30-40 days after flowering begins

Flowers develop into small seed heads. Foliage becomes coarser and less palatable.

Allow a few plants to complete flowering if you wish to collect seeds for next season. Leave seed heads on plant until fully dry before harvesting.

Harvest Tips

Begin harvesting outer leaves when plant has 6-8 leaves (typically 25-30 days after planting). Pinch or cut leaves 1-2 inches above soil level, removing from the outside in. Harvest frequently every 3-5 days to encourage continuous production and prevent flowering. Young, tender leaves are most flavorful. Leaves are best used fresh immediately after harvest but can be refrigerated in a plastic bag for up to 5 days.

Fun Facts

  • 🌱 Shingiku is also called 'tung ho' or 'Japanese greens' and is particularly popular in Japanese, Chinese, and Korean cuisines, where it has been cultivated for centuries.
  • 🌱 Unlike many chrysanthemums, this variety is bred specifically for consumption of its foliage rather than its flowers, though the flowers are edible and decorative.
  • 🌱 Shingiku is exceptionally fast-growing and cold-hardy, making it ideal for fall and winter gardens in temperate climates where many other leafy greens struggle.
