Planting and care

Sow Cosmos seeds in full sun or partial shade, in a moderately fertile, neutral, well-drained and humus-bearing soil. Sow the seeds from March to May for a flowering period from July to autumn. The cultivation of this plant is easy but they can be prone to aphids. Cosmos enjoys watering in the summer but it is still a fairly drought-tolerant plant.

Planting & care advice

  1. How to sow cosmos

Cosmos are easy-to-grow, long-flowering annuals (Cosmos bipinnatus, Cosmos sulphureus) ideal for borders, beds and pollinator-friendly gardens. Follow these steps for reliable results.

When to sow
- Sow under cover: 4–6 weeks before last expected frost.
- Sow outdoors: after all risk of frost has passed and soil has warmed.
- In mild climates: sow in autumn for early spring display.
- For continuous flowering: sow every 2–3 weeks until early summer.

Seed preparation and soil
- No special pre-treatment required; seeds can be sown dry.
- Choose well-drained, moderately fertile soil. Cosmos prefer lean to average soil; very rich soil encourages floppy growth.
- Position: full sun for best flowering.

How to sow
- Surface-sow or cover very lightly: press seeds into soil or cover with about 2–5 mm of compost or soil.
- Spacing: thin/plant out to 20–30 cm (8–12 in) for tall C. bipinnatus; 10–15 cm (4–6 in) for compact C. sulphureus.
- Germination: 7–21 days at around 18–24 °C; keep soil just moist until seedlings establish.

Practical care
- Watering: keep moist while seedlings establish, then water sparingly—cosmos tolerate drought and too much water reduces flowering.
- Feeding: little or no fertiliser; a light low-nitrogen feed encourages blooms without excessive foliage.
- Pinching: optional. Pinch growing tips when plants reach about 10–15 cm to encourage bushiness and more flowers, but note pinching delays first blooms slightly.
- Support: stake taller varieties in exposed sites to prevent flopping.

Maintenance and problems
- Deadhead spent flowers regularly to prolong bloom period.
- Pests/diseases: generally trouble-free. Watch for slugs on young seedlings and powdery mildew in humid, overcrowded conditions.
- To save seed: let heads dry on plant until brown, then collect seeds and store in a cool dry place.

Quick tips
- Sow directly where plants will flower to avoid root disturbance.
- Use succession sowing for long season of colour.
- Mix varieties for different heights and colours to create natural, airy displays.

With minimal attention, cosmos will reward garden with abundant, long-lasting flowers attractive to bees and butterflies. Tips
