🌱 How to Grow Coreopsis from Seeds

1️⃣ Seed Sowing

• Coreopsis can be directly sown where the plants are intended to grow.
• Prepare a fine, loose and well-drained seed bed.
• Scatter seeds evenly and cover them lightly with fine soil or growing medium.
• Keep the surface consistently moist.

RHS specifically recommends direct sowing Coreopsis tinctoria and lightly covering the seeds.

2️⃣ Germination

• Ideal temperature: approximately 15–20°C
• Keep the medium moist but not waterlogged.
• Provide bright light after sowing.
• RHS lists germination at around 30 days under the specified conditions, although actual results can vary with seed quality and environment.

3️⃣ Transplanting

Direct sowing is preferable where practical. If starting in seed trays, transplant young seedlings carefully once they are established and large enough to handle.

4️⃣ Spacing

Maintain around 20–30 cm spacing between plants, adjusting according to the variety and desired planting density.

5️⃣ Watering 💧

Water regularly during establishment.

Once plants are established, avoid keeping the soil continuously saturated. Coreopsis performs best in well-drained soil.

6️⃣ Soil Requirement

Use a fertile, loose and well-draining growing medium.

Recommended pot mix:

• 40% garden soil
• 30% compost/vermicompost
• 20% cocopeat
• 10% coarse sand/perlite

Good drainage is important for healthy root development.

7️⃣ Sunlight ☀️

Provide full sun for strong growth and flowering. RHS lists full sun as the preferred position for Coreopsis tinctoria.

8️⃣ Fertilization

Once plants are established, feed with a balanced liquid fertilizer at a mild concentration every 2–3 weeks during active growth.

Avoid excessive nitrogen, as it can encourage foliage growth over flowering.

🌿 Plant Care Tips

✔ Provide plenty of direct sunlight.
✔ Use fertile but well-drained soil.
✔ Keep young seedlings evenly moist.
✔ Avoid excessive watering and waterlogging.
✔ Maintain good air circulation.
✔ Remove faded flowers regularly to prolong the flowering display.
