Plump and fresh Australian Four‑Season coriander seeds maintain stable germination activity. Coriander (cilantro) is a widely‑loved aromatic culinary leafy herb, featuring upright sturdy stalks, dark‑green lush foliage and rich classic spice aroma. This special four‑season variety delivers fast growth performance, strong adaptability, tolerates partial heat and resists premature bolting compared with ordinary coriander strains. Both tender fresh leaves and mature seeds can be used for cooking, seasoning, pickling and herbal recipes. This 40‑gram small pack fits balcony container, home raised‑bed and large‑area field production. When building your culinary herb garden, you can pair it with 50gram organic caraway seeds to expand your spice‑herb planting selection. Coriander prefers full‑sun or partial‑shade location and loose fertile well‑drained loamy soil. Heavy water‑logged clay soil must be avoided to prevent root rot. Daily management focuses on moderate watering and timely harvesting of young leaves before bolting. It is a high‑yield beginner‑friendly leafy herb for home kitchen and commercial vegetable planting.
Planting Instructions Soil Preparation Choose sunny or light‑partial‑shade plot. Mix garden topsoil with decomposed organic fertilizer and fine river sand to form loose breathable substrate. For low‑lying areas, build slightly raised seedbeds to ensure rapid rainwater drainage. Compacted poor‑air‑permeability clay soil is not suitable.
Seed Pre‑treatment Coriander seed shell is hard. Crush whole seeds gently to split into two halves. Soak split seeds in clean cool water for 10‑14 hours to soften seed coat and boost germination. Discard floating bad seeds. No cold stratification needed.
Sowing Method Sow in spring, autumn or cool periods in summer. Broadcast evenly or drill in shallow rows, cover 0.5‑1 cm thin soil layer. Keep 10‑15 cm spacing between plants, 25‑30 cm row spacing. Thin seedlings after 2‑3 true leaves emerge.
Germination Condition Optimal germination temperature is 15‑22°C. Seedlings emerge within 10‑21 days under proper humidity. Keep soil consistently slightly moist, avoid water accumulation. High temperature above 28°C will suppress sprouting and trigger early bolting.
Daily Maintenance Water moderately, keep soil moist but not soggy. Remove surrounding weeds regularly. Apply diluted nitrogen fertilizer once or twice during leaf‑growing stage. Harvest young tender leaves 30‑45 days after sowing. Pick outer leaves progressively for repeated harvest. If you want to collect spice seeds, leave several plants to bolt and ripen.

FAQ Q1: Why should coriander seeds be crushed before sowing? A1: Coriander has hard round seed husk; splitting seeds helps water penetrate and greatly raises germination rate.
Q2: Can I grow this coriander in balcony pots? A2: Yes, it works perfectly for deep containers with drainage holes under sunny or light shade condition.
Q3: How soon can I harvest fresh coriander leaves? A3: You can start picking tender outer leaves 30‑45 days after sowing for continuous harvest.
Q4: What makes Australian Four‑Season coriander different from ordinary types? A4: It grows faster, better heat tolerance and slower bolting, suitable for longer‑season cultivation.
Q5: What causes coriander to bolt quickly? A5: Persistent high temperature, insufficient water and long daylight hours will trigger early bolting.
