FAQs

Please read our FAQs page to find out more.

When can I grow Cosmos in the UK?

Grow Cosmos in spring, then move it outside after the risk of frost has passed. It needs warm conditions and a sunny position to grow strongly.

Where is the best place to grow Cosmos?

Cosmos flowers best in full sun and light, well-drained soil. Avoid very rich soil, which can produce lots of foliage but fewer flowers.

Why has my Cosmos grown tall but not flowered?

Too much shade, rich soil or high-nitrogen feed can cause leafy growth with fewer flowers. Give plants more sun and avoid overfeeding.

Should I deadhead Cosmos?

Yes. Remove faded flowers regularly to encourage a long display and prevent plants from putting energy into seed production.

Can I grow Cosmos in pots?

Yes, compact types grow well in large pots. Use free-draining compost, place in full sun and water during dry spells.
