Thompson & Morgan Cosmos Apricot Lemonade - 1 Seed Packet (40 Seeds)

Sow seeds indoors from March to May. For direct sowing outdoors, wait until after the last frost, typically May or June.

Cosmos prefer moist, well-drained soil. They are not overly fussy but avoid waterlogged conditions, which can lead to root rot.

When fully established, the plants typically reach a height of up to 70cm (28 inches) and a spread of up to 40cm (16 inches).

Yes, deadheading spent flowers regularly is recommended. This encourages the plant to produce more blooms throughout the season.

Yes, they can be grown in pots, provided the containers are large enough and have adequate drainage holes. Ensure they are placed in a sunny location.

Pinching out the growing tip of each stem encourages the plant to branch out, resulting in a bushier plant with significantly more flowers.

The plants will keep flowering until the first frosts, providing color for an extended period from early summer through to autumn.

Ensure consistent moisture, adequate warmth (18-25°C), and that light is not excluded. Check the age and viability of your seeds.

Provide more light. Ensure they are not overcrowded and are growing in suitable compost. Avoid excessive nitrogen feeding.

Confirm the plant is receiving full sun (at least 6 hours daily) and has adequate drainage. Avoid over-fertilizing with high nitrogen content.

This often indicates overwatering or poor soil drainage. Ensure the soil is well-drained and allow the soil surface to dry slightly between waterings.

Ensure the growing tip was pinched out after transplanting outdoors. Regular deadheading also encourages further blooming.
