FAQs

Please read our FAQs page to find out more.

When can I sow Zinnia seeds in the UK?

Sow Zinnia seeds indoors in spring, then plant them outside after all risk of frost has passed, usually from late May or early June. In warm, sheltered gardens, seeds can also be sown directly outdoors once the soil has warmed up.

Can I grow Zinnias in pots?

Yes. Zinnias grow well in pots and patio containers, provided they receive plenty of sun. Use a container with drainage holes, fertile compost and enough space for air to circulate around the plants.

How do I keep Zinnias flowering for longer?

Remove faded flowers regularly to encourage the plant to produce more buds. Keep Zinnias watered in dry weather, give them full sun and avoid high-nitrogen feeds, which can encourage leaves rather than flowers.

Why do Zinnia leaves have white powder on them?

This is usually powdery mildew, a common problem in crowded or damp conditions. Give plants good spacing, grow them in an open sunny spot and water the soil rather than wetting the leaves.

Do Zinnias come back every year?

Zinnias are usually grown as annuals in the UK. They grow, flower and set seed in one season, then are killed by the first frost. Sow fresh seed each spring for a new summer display.
